Human Muscle Anatomy 1

Correction: The muscle I called the Lats are actually part of the Trapezius! The lats are along the sides, which I didn't point to in this video. The lats are sometimes called the "wings" that swimmers often develop.

Another bit of correction caught by one of the viewers: "at 7:32 you made a mistake.The rectus abdominus is actually not the most superficial muscle. Its located in the second layer, just medial to the internal obliques. Also, the muscle you identified as the external oblique are actually the internal obliques.

The most superficial muscle in the abdominal region is the external obliques. The part the covers the majority of the rectus abdominus is the abdominal aponeurosis."

I'm sorry about the mistakes and any confusion they may have caused!

So the Platysma covers the anterior portion of the cervical that's not shown in this video? Is it considered a superficial or deep skeletal muscle? I'm guessing it's a superficial muscle but I want to clarify.

@ReinaDelAcordeonMimi You got it. The platysma that covers the neck region is a superficial muscle. It overlaps the sternocleidomastoid muscles located laterally to where you would find the atom's apple. Hope that helps!

@jetlex1 Thanks =) A few more question... Is there a suprahyoid (superior to hyoid) and infrahyoid (inferior to the hyoid) muscle? What are their purposes? Sorry, I have a lab practical and lecture exam next week and I want to make sure I have everything down. It's very stressful lol

@ReinaDelAcordeonMimi I guess the hyoid is a bone that's somewhere below the floor of the oral cavity and north of the larynx and the supra/infrahyoid muscles helps you swallow among other things. I'm not sure if my model shows the supra/infrahyoid, but there's a good video that focuses just on the hyoid muscles. It won't let me copy/paste the link but search on youtube for "Head and Shoulder Model - Suprahyoid Muscles" Check it out . I think it'll help you.

Hi, i have a question about the rotator cuff. I had 2 teacher who taught me anatomy and they said different things. One said whats in the video, and the other said that the rotator cuff's parts are the infraspinatus, the teres minor, the subscapularis muscle and the teres mayor. He stated that the supraspinatus is not part of the rotator cuff cause it doesnt rotate the humerus, it only helps in the abduction of the arm, but the teres mayor rotate the humerus inward.

So who do i believe now?

[jetlex1]

@Hordleran Sorry ran out of room. What does your text book say?  Maybe he meant teres major isn't one of the rotator cuff muscles?

[myrddinistheshit]

i could fucck you for this great video

[ulujm]

where hi can you buy this model and is it possible to move part and see how muscle move?

thanks

[jchristolin]

@6:36 is wrong, the latissimus dorsi is lower, its under the teres major.

Thx this will help me study 4 my bio test

@Hordleran Teres major is not part of the rotator cuff. the Rotator cuff consists of the infrapinatus, subscapularis, teres minor, and the supraspinatus

@jetlex1 Ok thank you =)
