triceps
trapezius
lateral rotation
The long head from infra-glenoid tubercle, the medial convers most of the posterior area of humerus and the lateral from a ridge above the spiral groove. That is for the brachii Or do you mean Surae?
A flexor muscle is a muscle which bends or flexes a limb. Most flexor muscles are located on the anterior aspect of the body.
The primary muscle attached at the point of insertion is the muscle that undergoes the most movement when the muscle contracts. For example, in the bicep curl exercise, the bicep muscle is the primary muscle attached at its point of insertion on the radius bone in the forearm.
Latissimus Dorsi
Lateral epicondyle of the humerus.
The medial epicondyle is the most medial structure of the humerus. The trochlea is the second.
The occipital bone is most posterior.
none as the joint ca[sule is an inert structure meaning no contractile tissue
The anatomical neck is the one that looks like the neck from an anatomy point of view-it is between the head (that goes into the shoulder) and the tubercles. The surgical neck is the site where most fractures occur. It comes just after the tubercles. Remember that the humerus is kind of in the shape of a "7" going into the shoulder joint, so the anatomical neck is like if you cut from the top with a knife, and the surgical neck is if you cut from the side.
Most polite people would sit on their posterior.
