Anatomy & Physiology B/C

Do you think we would need to know the bone markings of the bones in the appendicular and and axial skeleton at a regional/state level?

I would say that you might need to know the types of bone markings and be able to identify them on a diagram, but you wouldn't need to know specific bone markings on specific bones. Someone else might disagree with me, though. Basically it comes down to how you interpret rule 3.b.i. in terms of "label the basic surface anatomy of a bone". Maybe an FAQ should be submitted.

I'd suggest you know them, sicne you never know what proctors will ask for this event (plus I've actually seen them on a test, and not knowing them cost me a medal).

Not yet, but I will this year! (fingers crossed)

Am I right in assuming that you were in B division last year? I saw that you were from Interlake and was just wondering, because I thought I saw Interlake at Nats last year.

Haha well I'm a senior, so it's my last chance to go to Nats as a competitor, but I was there in spirit watching the opening/awards ceremonies on livestream!

Oh, oops. Guess I was wrong.

How in-depth do you guys think I should go on excitation-contraction coupling, action potentials, etc? I'm so confused. Right now I'm studying from Human Anatomy & Physiology by Marieb and Hoehn. It seems to have a whole chapter dedicated to that kind of stuff, and I'm not sure how much I should read, considering I have a tryout test for this event in 8 days and still haven't finished my cheat sheet.

Edit: What about muscle metabolism?

Hmm.. I would think to go pretty in-depth with those first two topics since they're included within the topic "Physiology of the skeletal muscle contraction system." For muscle metabolism, that would probably be included more in classes of muscle fibers in the nationals topics. So you'd probably have to know only the basics unless the tryout test includes national topics.

Also, has anyone studied parallel and series elastic components of skeletal muscle? I'm having trouble understanding it/finding resources about it

Thanks for the response!!
I haven't studied that yet, but this looks good for basic info: http://www.kean.edu/~jeadams/docs/Biome ... ap%206.pdf

There was a new test that was posted on the Test Exchange for Anatomy by the user Sanjanakonda2002. The test was very well written, but I think that I found some errors in the answer key. If anyone is willing to check them out and reply to me about them, I would greatly appreciate that.

The errors were in the first 20 questions of Section 1.

Question #3 (on the anterior view of the body): The answer key said that the muscle was the pectoralis major, but I am pretty sure that it is the serratus anterior. Also, the answer key said that Question #8 is also the pectoralis major.

Question #6 (on the posterior view of the body): The answer key said that the muscle was the gluteus maximus, but I am certain that the muscle is the triceps brachii. The gluteus maximus is located on the butt, and the arrow is pointing to the arm, so...

Question #7 (on the posterior view of the body): The answer key said that the muscle was the gluteus medius, but I am sure that the muscle is the teres major. Again, the gluteus medius is located on the butt, and the arrow was pointing to the upper thorax.

Question #8 (on the posterior view of the body): The answer key said that the muscle was the triceps brachii, but I am certain that the muscle is the teres minor. The arrow was pointing the thorax, and the triceps brachii is located on the upper arm.

Thanks!

I just took that test for practice yesterday, and noticed the same things. I found the 2nd image on google images though. They look to be the same image; and according to the diagram, the answers are the following.

3. I think it is the serratus anterior.

6. Definitely not the gluteus maximus. I think it is the triceps brachii.

7. Yeah, not the gluteus medius. Teres major looks right though.

8. I put teres minor for that one.

EDIT: Actually, looking back at my test, I put infraspinatus for #3 on anterior view. I could be wrong though!! (I am really bad at labeling )

Edit 2: I'm stupid... I put infraspinatus for #3 on POSTERIOR VIEW, I put PECTORALIS MINOR for #3 on anterior view.

[sciolyFTW_aku]

Thanks for clarifying. I am pretty sure that #3 on the anterior view is the serratus anterior because the muscles are serrated (look like teeth) and the muscle is located in the front of the body (hence the name serratus anterior (front teeth)).

Edit: Does anyone have any websites/resources for muscular and skeletal diseases?

Edit #2: Actually, forget what I said above. I think that the muscle is the pectoralis minor.

[watermydoing14]

Serratus anterior is a little lower and more on the side of the body, covering the ribs. I noticed that some of the muscles on that test are not included in official 2016 muscle list (teres minor, pectoralis minor). How likely is it that a test at an actual competition will have you label muscles that are not on the official list?

Serratus anterior is right (just for a second opinion). I could see that some muscles that are not on the list being used as some ES might completely disregard it. For example if some is making an A&P exam they might just pick muscles that they know or like and not even look at the list. Again it depends on the ES.
