Bio was awesome

Hey guys, it's shereen, just wanted to drop a last post and say how much fun it was to spend biology class with all of you, it was a blast and i hope to see you guys around next semester. PEACE OUT all!!!!!! :-) now, i will leave with some pics from class for memory's sake.

Big-ass study guide

Ok, so I posted MOST, not all of the study guide (some questions I am still working on) on zohowriter because it would be too big for this blog and it would knock all the other good stuff down to the way bottom.

Click here: Study Guide

Also, some stuff to help you guys out.

Scans from my sister's book on fascial tissue and muscle groupings, etc.

Here are some websites too

Diagramatic (sp?) layout of the brain

http://upload.wikimedia.org/wikipedia/en/f/f3/EmbryonicBrain.png

This is a very cool site that explains the ear and the basic differences between perilymph and endolymph fluids

http://thalamus.wustl.edu/course/audvest.html

That is all I have for now. Have fun and e-mail or comment with any suggestions you guys have.

Much to do about anatomy.

Ok, here are some videos from our last dissection session. Special thanks to Melissa for doing the narrative on some of these.

If you guys need any videos for your study purposes, let me know before Sunday so I can make some while I am in lab (don't be shy, it helps me study too, you know!)

Enjoy, fellow bio nerds!

Ductus Arteriosa Stuff

OK Navid....

So I did some of the questions per Navid's taunt, but there are more to come as I had to skip around and juggle some time. I will be answering more later and I am open to corrections and comments as this blog is for the class. Let the games begin.

192) What is ethology?

a. The study of instinctual behaviors.

193) Describe sign stimuli and give examples.

a. Sign stimuli are stimuli that initiate an IRM (Innate Response Mechanism), which then triggers an FAP (Fixed Action Pathway, or action)

194) What are innate releasing mechanisms (inn's)?

a. A pre-programmed response to a certain stimulus.

195) Describe and give examples of the following types of learning: habituation, conditioning, classical and operant conditioning, generalized and discriminating conditioning, latent learning, insight learning, imprinting.

a. Habituation: Not responding to stimuli (grass under the feet, etc)

b. Conditioning: learned response to a stimulus that is reward based.

i. Classic: one stimulus substitutes for the natural one. No reward needed.

ii. Operant: present the behavior, get the reward.

iii. Generalized: similar stimuli generate the same response (Think baby Albert and the white rabbit)

iv. Discriminatory: only specific stimuli generate a response. (gunshot vs. popping a paper bad)

c. Latent learning: Experience that leads to faster problem solving (exposure to a maze will give one a better chance of completing it faster than one who has not.

d. Insight learning: Mental problem solving.

e. Imprinting: Fast learning done at certain times in life (ducks associating first thing they see as “mother”

196) What is the relationship between memory, engram, retrieval, and long-term memory, short-term memory.

a. Memory: retainment of facts, etc.

b. Engram: New/Permanent circuitry in the brain.

c. Retrieval: ability to recall memories stored in LTM.

d. Long term memory: Memories that a hardwired into the brain. Happens in 1^st hour of STM.

e. Short term memory: memory that exists only in existing circuitry. Will break down if not transferred to LTM.

197) Describe the role of the following in communication: coloration, tags, posture, eye contact, sound, pheromones, and chemicals.

a. Coloration: communicates gender

b. Tags: Communication without compromising silence (like tigers and cubs)

c. Posture: Body Language

d. Eye contact: dominance/submissiveness,

e. Sound: Distance communication

f. Pheromones: Chemical communication

g. Chemicals: communicates location, reproductive ability, etc.

198) How is behavior related to the genetic isolation that forms a species?

a. Because most species cannot intercommunicate (e.g. polar and grizzly bears). Different languages mean that one does not understand the other, limiting or nixing the chances of interbreeding.

199) Describe the role of aggression between and among species.

a. Intraspecific aggression: Protecting harems, protecting territory, etc.

b. Interspecific aggression: Protect food supplies, territory, take out aggression (wolves killing coyotes?)

200) Give examples of social behaviors.

a. Mutually beneficial behaviors, such as preening, caring for another’s young, moving as a herd.

201) Describe and give examples of the following: intraspecific and interspecific cooperation, altruism.

a. Intraspecific cooperation: Pack hunting

b. Interspecific cooperation: “Tick birds” that warn their “favorite” animals of immediate danger.

c. Altruism: Taking a bullet for someone to protect them.

Eye and Brain Anatomy.

So here is the Eye Anatomy.



Brain anatomy explained by our good Professor Sourbeer.

No more messing around

In an attempt to study better than I have been, I took it upon myself to download a demo version of Readiris (text recognition software,) scan in the lecture study guide outline and convert it to text so I (or other students) can type in answers, space out the questions so you can handwrite answers, etc.

As it turned out, there are some typos (hey, it is text recognition, not perfection) and some missing questions that I cant seem to find but I am sure are in the text but they are simply hidden (I ended up with 130 of the 133 questions... 97.7% success rate!)

I will be posting video and eye videos later. For now, here are the questions (I started them off at their original number, 192, so that you guys could reference the questions easier.) Enjoy!

The very long and somewhat humorous animal classification...

Hi and welcome to the classification of animals you shall see in our lab exam this tuesday! I'm going to try to condense it down (and add a bit of wittiness!) so it is easier for you all to get...and it helps me remember it as well. ready or not, here it comes...

KINGDOM: Metazoa (animals)

Subkingdom: parazoa: the "p" category--only two phyla

• Phylum Porifera--sponges (sponges have PORES!), acoelomic, have choanocytes which flow water through the sponge through porocytes and out the osculum (the mouth of the sponge at the top). there are three body types: asconoid, which is just a big single cavity, syconoid, which have side chambers, and leuconoid, which have side chambers coming off the other side chambers...geez..
• Class Calcerea, made of calcium carbonate (no DUH); scypha/grantia are examples. this is an actual picture of it from the lab--if you see a jar of these, it is scypha/grantia. the purple blob is a widthwise slice.
  
• Hexactinellida (hexa--six pronged) has six pronged spicules...looks like two mercedes benz logos stuck together. it is a long white delicate tube thing in lab.
• Desmospongidae--spongy sponges. the ones in your house.
• sclerospongidae--hard sponges. not sure what they look like...google says this:
• Phylum Placozoa: (small multicellular animals found in aquariums...like, placozoa, the ugly plaque on the wall or something?) ;-)

Mesozoa: they are tiny little things we really shouldn't care about...
Eumetazoa: "eu-" means real--these are real animals. there are two superphyla (its a bird! its a plane! NO! its superphyla!) Radiata, and Bilatera.

• Superphyla Radiata: diploblastic (only endo and ectoderm) show radial symmetry (hence the name).
• Phylum Cnidaria--jellyfish, anemones, corals. have ocelli (light sensitive yet not quite an eye), mesoglea (the gooey stuff in jellyfish!) and cnidocytes to sting prey. these hurt...trust me. there are polyps (looking up, an anemone) and medusa (looking down, a jellyfish). There are three classes to know:
  
• Class Hydrazoa, polyp dudes..which include hydra, obelia, Portugese man-o-war. the man o war is NOT a medusa, the top part is an air bladder.
  
• Class Scyphozoa, jellyfish.
• Class Anthozoa (remember last exam, anthophyta, the flowers? antho- means flower) corals and anemones.
• Phylum Ctenophora; lack cnidocytes
• 

• Superphylum Bilatera includes everything else.
• (Acoelomic) Phylum Platyhelminthes;
the flatworms. triploblastic beauties! hermaphroditic! squishy! Classes:

• Class Turbellaria, a Dugesia (planarian). its head looks like a bell...TURBELLARIA! ONWARD!
• Class Trematoda, which has two subclasses, Digenea, the disgusting worms that live in your liver and intestines (Chinese liver fluke and Schistosoma mansoni--know life cycles) and Monogenea (parasitic of fish gills).
• Class Cestoda, tapeworms. they have a scolex (attachment part to host) a strobilus composed of proglottids (reproductive units that make eggs)Examples are Taenia saginata (human beef, sheep, pork, fish) tapeworm and Dipyllidium caninum (dog tapeworm). know the life cycles!
  

• (Acoelomic) Phylum Nemertea (proboscis worms)
• (Pseudocoelomic) Phylum Nematoda, dioecious, free living and parasitic, some parasitic examples include Trichinella (pork worms), Enterobius (pinworms), Ascaris (we dissected these, the white worms), and Ancylostoma (hookworms)
• There are some other phylums of these worms, you should read about them in the study guide.
• (Eucoelmic) Phylum Mollusca; they have a well developed circulatory system and heart; all members (almost!) posses a radula, a plate in their mouth that scrapes food...like a spatula...lol. a mantle which is a bunch of cells that secrete a shell and a cavity with gills and siphons. a foot for moving around. and well developed organs. the classes are:
• Class Gastropoda (snails and slugs)
• Class Pelecypoda/Bivalvia: Clams, oysters, etc.
• Class Polyplacophora: chitons, eight overlapping plates
  
• Class Scaphopoda:they look like worms in an elephant tusk.
• Class Cephalopoda: Octopus, squid, cuttlefish.
• KNOW LIFE CYCLES.
• Phylum Annelida; segmented worms. triploblastic, protostomates, septa separate each segment, have setae (WORM HAIR!!!!)
  
• Class Oligochaeta, earthworms; (oligo- means few, chaeta means setae, oligochaetea means FEW SETAE wow i'm impressive); the clitellum is the reproductive part, closer to the head, is lighter colored. Know life cycle! (and no, i did not draw this awesome diagram)
  
• 
• Class Polychaetes (many setae, many hairs); the little legs are called parapodia.
• 
• Class Hirudinea, leeches; have posterior sucker. no photo, you should know what a leech looks like. :-)
• Phylum Onychophora (walking worms); nothing really to say more about them.
• 
• Phylum Arthropoda (joint footed animals). Have chitin in exoskeleton; some external segmentation; many are social (party animals...he he)
• Subphylum Trilobitaall members extinct.
• Subphylum Chelicerata; lack antennae, with two oral appendages (like fangs, pinchers, etc.), have book gills/lungs; typically four pairs of walking legs; two body regions, the cephalothorax (cephalo- means head, thorax- means thorax..uh..) which is the head and thorax joined together, and the abdomen.
• Class Merostomata, horseshoe crabs there is one of these in lab...it looks like a gigantic cockroach underneath..actually....here.they are harvested for blood.
• Class Arachnida; spiders, ticks, scorpions, mites. you won't forget the arachnids!
  
• Subphylum Crustacea; cephalothorax and abdomen, two pairs of antennae.
• Class Branchiopoda, fairy shrimp and water fleas.
  
• Class Copepodahave one very long antennae, held at right angles...this poor thing has to cope with his long antennae. poor copepoda.
• Class Cirripedia, barnacles. Very serious creatures they are indeed.
• Class Malacostraca; they have a rostrum, carapace, abdomen, and telson (i don't think you need to worry about these parts of the animal).
• Order Decapoda; shrimp, lobster, crab...
• Order Isopoda; no carapace, no distinction from thoracic and abdominal segments...and they're flat. but can roll up. an example: a pill bug.
• Order Amphipoda:there, just think flat shrimp. the first few segments are fused with the head.
• Subphylum Uniramia; in other words, lovely insects.
• Class Insecta; head, thorax, abdomen; one pair of antennae; three pairs of walking legs; spiracles which allow air to flow through to have gas exchange occur (they are like lungs, but not). Metamorphosis is either complete (egg > larva > pupa > adult) or incomplete (egg > nymph [which is a small adult] > adult)
  
• Please, please, look at the orders yourself.
• Class Chilopoda, centipedes. They are chillin. They have one leg on each segment of their body.
• Class Diplopoda, millipedes. they have two legs on each segment of their body. (di- two, diplopoda, two legs a segment? yeah? we good? jk/jk)

Ah, yes. I have been madly typing for hours, and now I need rest. otherwise i might mislead you into thinking millipedes are a member of the nematoda phylum, and i know you know better than that. i will try to post the rest beyond protostomates tomorrow. goodnight all..sweet dreams.

Sheep Heart Dissection Stuff

I have decided not to post a video for the sheep heart dissection for several reasons, some of which are that the heart I have isn't the best "fileted" one and I have found a very good video explaining a lot of what we need to know. The intro to the video is not applicable but everything else is. Link is here:

http://www.zerobio.com/videos/sheep_heart_anatomy.html

Enjoy! See you guys Thursday!

Shereen's Clade-o-gram

Whoops! Shereen reminded me about her chart so I posted as soon as I got home. I had to split it in 2 so that you could actually read the page. Just put the images into Word and print it off as a joined page or something.

Part 1: http://i13.photobucket.com/albums/a276/pullnshoot25/biology/scan1part2.jpg
Part 2: http://i13.photobucket.com/albums/a276/pullnshoot25/biology/scan1part1.jpg

I will be posting videos on the lamb heart later, but right now I have to head down to my lame econ class. Ciao people.

-Nate

Shereen here!

okay everybody, just posting really quick to say that i made comments able to be made by all, it will be anonymous. and i am working on writing the entire classification system of all the species we have learned since exam 1, but alas...nate took my paper and didn't give it back. lol! see you tomorrow.

Skeletal, Muscle and Comparative Anatomy

Ok, I took a bunch of pictures of various displays in the lab for all you guys who couldn't make it to look at. I have pictures of the "muscular mannequins" (for lack of a better description), most of the animal skeletons and the forelegs of the cow and horse. Link here: http://s13.photobucket.com/albums/a276/pullnshoot25/

Here are 2 videos that I shot today for Arm and Upper Back/Shoulder muscles.

Arm:

Upper Back/Shoulder

No video for this one because I found 2 sites with some decent photos on them for you guys to look at.

Horse Anatomy


Cow Anatomy


I also found this site which I thought was pretty cool. These guys paint watercolors on this one white horse and then film/take pictures while it is in motion. The pictures arent too big as they want to maintain the rights to them but it is quite interesting to see.

http://www.anatomyinmotion.com/vhorse.htm

There you guys go. I will post more pictures later.
