Anatomy B/C

[2win]

OMG THANK YOU SO MUCH. No wonder you got first in anatomy! You're amazing!
So, for clarification: origin, insertion, and function for each?

Insertion: The point or mode of attachment of a skeletal muscle to the bone or other body part that it moves
Origin: The point of attachment of a muscle that remains relatively fixed during contraction

Well, its only 1st at regionals. Thanks
I am glad I helped. When is your state exam? I am personally freaking out

States for me is April 30th, Whens yours? And I'm actually not competing in anatomy at states. But that's ok.
However I got 4th in anatomy at regionals... :/

Its nice to see that somebody is studying just for the sake of learning...not to win first prize.
Mine is on April 24th. well, goodluck to you.

Ok, I understand your concern. Think of it this way: the frontalis is part of the occipitofrontalis. The frontalis is the section over the forehead but the occipitofrontalis is at the back of the forehead. It originates in the occipital bone. When you frown, notice that the pressure is applied on the forehead. There isn't much that your back of the head is doing which is why the frontalis PRIMARILY aids in frowning and raising your eyebrows.

The frontalis and occipitofrontalis is attached with layer of fibrous connective tissue called the aponeurosis. The occipitofrontalis is divided into two sections at the front and at the back of the scalp. The frontalis is the section over the forehead, arising from the skin, overlying the eyebrow and passing back to become continuous with the aponeurosis.
I have added a visual for you to understand.

Hope this helps

I have a question though...
If asked to label these 2 muscles then where exactly would each one be?
If the frontalis is part of the occiptofrontalis, then couldn't you possibly label the frontalis as occipitofrontalis?
i ask this because i haven't been able to find a single decent diagram with the occiptiofrontalis on it.

That one's not the best, but I don't know what to tell you.

I have just discovered that there is apparently: the extensor digitorum (hand), the extensor digitorum brevis (foot), and the extensor digitorum longus (foot).
I just want clarification that the one we need to learn is the one in the hand?

Also, is there such thing as origin, insertion, and function for the Thoracolumbar Fascia? I have that it:
-covers deep muscles of back
-attaches medially to spines of vertebrae - inferiorly to ilium (pelvic bone)
-Provides for muscle attachments

But that's not necessarily origin, insertion, and function.

Ohh ok so the epicranius is the occipitofrontalis

Ohh ok so the epicranius is the occipitofrontalis

Yes, they are the same thing.
