Either the sternocleidomastoid or the trapezius.... but because the sternocleidomastoid is not technically on the shoulders, nor the trapezius a "strap" I am a little confused by this question.... But I think the sternocleidomastoid is the best answer for this question aside from the reference to descent towards the shoulder. Hope this helps, a little ambiguous, I know.
Yes, it is. The external jugular passes over (superficially) to the sternocleidomastoid.
Infraspinatus.
Shoulder external rotation
The scientific name for the shoulder muscle is the deltoid muscle.
The deltoid muscle is located around the shoulder at the top. There is a deltoid muscle that is located on each shoulder.
The muscle that attaches to the external occipital protuberance is the trapezius muscle. This large, triangular muscle extends from the back of the skull and the cervical and thoracic vertebrae down to the spine of the scapula. Its upper fibers are particularly responsible for elevating the shoulder blades and extending the neck. Additionally, this attachment point plays a role in head and neck movement.
which shoulder muscle allows you to adduct your arm
Yes, the shoulder press machine is effective for building shoulder strength and muscle. It targets the deltoid muscles in the shoulders and can help improve overall shoulder stability and muscle development.
the shoulder muscle extends the arm
The shoulder muscle that is considered the strongest supinator is the biceps brachii.
The Deltoid muscle .
The trapezius muscle is a superficial muscle of the neck and upper back that acts at the shoulder. It is responsible for movements like shoulder shrugging, scapular elevation, depression, retraction, and rotation.
