A&P 1 Spring 08

Published

Hi y'all! Anybody taking A&P 1 this coming spring semester? I'm trying to get as many pre-req's out of the way as possible and could use a study buddy or 2! Thanks! :)

Our lab quizzes are actually super easy. I think the teacher has made them easy on purpose because we've missed some class due to really bad ice around here lately, so rather than make us have to learn whole chapters on our own, he made the quizzes a bit easier than he normally would have. But I still study for them like they're going to be impossible!

I got an 84 on my second exam in A&P! I was really hoping for an A, but I'll take an 84 (considering I got a 70 on my first one!) Nothing substitutes for just good-old fashioned studying, studying, studying!

Hello Everyone,

I just wanted to share my excitement with you...I got a 100% on both my lecture and lab tests last week!!! WOOHOO!!! :yeah:Thank you to all who've posted helpful tips and links. I have utilized them and it paid off!! :twocents:

Good luck to everyone else....

Lab practical is tonight...kinda freaking out! I've studied and studied, so all I can do is my best right? I just wish it wasn't 45% of my total grade.:chair:

Hey I think you'll do fine! All you can do is YOUR best. Remember that...sounds like you've studied a lot and you'll probably do fine. At this point I would suggest getting your mind off the exam by drinking some tea, watching your favorite show. If not you'll freak your self out. I recommend that you don't open your book at all because that just builds the anxiety level. You'll do fine!;)

OK this might seem silly...

With neurons, I wanted to know what is the best way to differentiate unipolar, bipolar, and multipolar neurons. I am confused when it comes to the processes and do all three (uni, bi, & multipolar) have Schwann cells or is this only for the unipolar and multipolar neurons?

My book does not really go into detail, but does show pictures but it is hard to understand when unipolar and bipolar look exactly the same...can anyone suggest something for this?

Thanks!

Not silly at all! I had a really hard time with that, too. Bipolar neurons are simple - they're uncommon and are only found in the special senses, like the retina of the eye, auditory and olfactory systems. Unipolar neurons are the sensory or afferent neurons, most common in the dorsal root ganglia. Multipolar neurons are the most common neurons in the body - they are association neurons. Found in the CNS, they link motor and sensory neurons together.

Here's a good link that has a lot of animations and information on the nervous system. I found it really helpful with figuring out the CNS and PNS, looking at all the neurons and support cells, and in figuring out action potentials (the animation for that one was a life saver!)

I got my lab practical back last night and got a 76. Not great but my professor said not to worry that a 76 is good, so I'm not going to worry. We took our lecture exam last night an I feel that went very well. We will get our grade on the lecture exam on Thursday. :bugeyes:

what about when it comes to the 'drawings' of all three?

1. ** [color=#3366ff]where i am confused is when it comes to the 'drawings' of the unipolar, bipolar, and multipolar neurons. i noticed that multipolar and unipolar are the same looking-wise when it comes to having axons, which from what i gather the only that have axons are only unipolar and multipolar neurons...is this correct?

2. ** [color=#3366ff]my book says that unipolar only have one process but from the drawings in the book it seems like they have more than just one...am i wrong?

3. ** [color=#3366ff]i am also confused because on my book it seems that they all have many dendrites, does it vary on how many dendrites they have when it comes to each (uni, bi, and multi)?

4. ** [color=#3366ff]unipolar neurons have t-like processes but then again when i look into the book (to me) they look like they all have the t-like process.

sorry for all the questions, i am just so confused on all these!

THANK YOU GOD!!!!! Got my lab practical grade back today and it's a 92!!!!!:w00t:One down, one to go! I couldn't have done it without ya'll!

types of neurons - the three main types of neurons are:

multipolarneuron.gifmultipolar neuron

unipolarneuron2.gifunipolar neuron

bipolarneuron.gifbipolar neuron

multipolar neurons are so-named because they have many (multi-) processes that extend from the cell body: lots of dendrites plus a single axon. functionally, these neurons are either motor (conducting impulses that will cause activity such as the contraction of muscles) or association (conducting impulses and permitting 'communication' between neurons within the central nervous system).

unipolar neurons have but one process from the cell body. however, that single, very short, process splits into longer processes (a dendrite plus an axon). unipolar neurons are sensory neurons - conducting impulses into the central nervous system.

bipolar neurons have two processes - one axon & one dendrite. these neurons are also sensory. for example, biopolar neurons can be found in the retina of the eye.

not sure if this helped but i pulled it from http://people.eku.edu/ritchisong/301notes2.htm, maybe this will help. i already filed all of my notes from a & p i so i don't have anything on hand. does your text book have a companion site or maybe try searching here, i know there is one post that had lots of helpful links for a & p i.

:yeah: I got my results back for my first test (CH 1-4) I got a 100% in both my lecture and lab I know that with the :bowingpur Lords help and all that studying paid off:bugeyes:

Now I need to start on my my next test (Bones).
