Human Anatomy / A&P I Club for Fall 2007

Published

I'm starting human anatomy next week, and would love to get a sticky started to keep each other sane. I'm a bit nervous about starting this class, as I really need an A, but work full-time and will also be taking abnormal psych. It's going to be a lot of work! :uhoh3:

Let's help each other out through this forum! :welcome:

So, when are you starting, where are you taking it, and how are you feeling?

Hi everyone...I'm new here and just wanted to introduce myself. BTW I take my AnP final next thursday, and the cranial nerves will surely be on it!!;)

(I also have a Chem final that monday, Sociology final tuesday, AnP LAB final on wed, and a foreign culture final on friday.......FUN WEEK AHEAD:uhoh3:)

Hello everyone here on Allnurses! Count me in on this endeavour of Human A & P. I found a great link that will be helpful to anyone on here. It is a BBC site and I find it to be very informative and helpful. http://www.bbc.co.uk/science/humanbody/ check it out and I hope it serves everyone well. I start my A&P classes Jan 14, in the mean time I'll be studying and preparing myself during this holiday break. My best of wishes to everyone. Lets tackle this course head on!

This question is on a take-home test, and I can't find the answer anywhere...HELP!

Stimulation of a neuron that terminates in the superior portion of the left postcentral gyrus would produce:

A. a muscle twitch in the face

B. a muscle twitch in the leg

C. both sensations and muscle twitches in the right leg

D. a sensation in the leg

E. a sensation in the face

MissRNstudent,

What I have been able to find so far is that the postcentral gyrus is in the parietal lobe of the brain and is a primary sensory area. So, I wouldn't think that it would cause an action, but it would cause sensation. I hope this helps!!

according to the sensory and motor homunculus...sensory and motor sensation for the legs is in the superior postcentral gyrus....look up sensory homunculus or motor homunculus in google to make sure.

hello there, i was a bit confused to see the question be on superior postcentral gyrus. if you are looking at it in a sensory homunculus picture it would be considered on a medial or lateral side. but anyways i guess superior would be medial and inferior would be more to the lateral side. so if that was the case then d would be my answer. i read the previous post and the motor homunculus is not in the postcentral gyrus. it's in the primary motor cortex or anterior central gyrus. don't want you to get confused. all that homunculus means " the little man in our brain" it's just a pic to tell you if something happen to a certain part of your brain, what would be affected. you have to find a pic of it is really cool.

keep in mind that we have two major (elevation called convulsions or gyrus). if you are looking at a pic of a lateral side of a brain you will be able to see them next to each other. what devides them is a 'sulcus" which is a crease that we have all over our brain that are usually 1/2 cm in depth. called: central sulcus. we have even more deeper creases in our brain called fissure.

the two main gyrus:

1. anterior central gyrus (primary motor cortex)

2. posterior central gyrus (primary sensory cortex)

you can see it has two names. the 1st is the anatomical name and the second is the name for it's function.

1. is the one that immediately runs your muscles if something happens to this area you will be paralyze.

2. creates your perception of tactile sensation if something happens to this area then the area of your body that is affected will cease to exist from your consciousness. so you will not know where it is but if you look at your foot for example you can see is there but one you don't look at it, in your mind it doesn't exist.

the motor or sensory homunculus determines if the injury occurs on a medial side (superior) it affects the lower part of your body. if it happens more on a lateral side then is more upper. this is why i was a bit confused but if inferior mean lateral then i would say the sensation of the legs.

sorry kind long but is hard to explain it good luck!
