The coracoid process acts as an attachment and origin for a large number of muscles (attached muscles not labeled here). The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; [2] it runs at first upward and medially; then, becoming smaller, it changes its direction, and projects forward and laterally.
Synergist muscles also called fixators, ... The connective tissue of the attachment is called an enthesis. Origin. The origin of a muscle is the bone, ...
The outer gives attachment to the adductor magnus; The inner to the sacrotuberous ligament; The upper portion is subdivided into two areas by an oblique ridge, which runs downward and outward: From the upper and outer area the semimembranosus arises; From the lower and inner, the long head of the biceps femoris and the semitendinosus
Thus the words (enthesis and insertion [of muscle]) are proximal in the semantic field, but insertion in reference to muscle can refer to any relevant aspect of the site (i.e., the attachment per se, the bone, the tendon, or the entire area), whereas enthesis refers to the attachment per se and to ligamentous attachments as well as tendinous ones.
Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the others being cardiac muscle and smooth muscle. They are part of the voluntary muscular system [ 1 ] and typically are attached by tendons to bones of a skeleton .
The biceps is a particularly powerful supinator of the forearm due to the distal attachment of the muscle at the radial tuberosity, on the opposite side of the bone from the supinator muscle. When flexed, the biceps effectively pulls the radius back into its neutral supinated position in concert with the supinator muscle. [14]: 346–347
Alternatively, the term may have been influenced by the Greek τροχαντήρ (trochantḗr), which referred to the protrusions on the stern of triremes that served as attachment points for ropes and sails. In a similar manner, the anatomical trochanters are prominent bony projections that serve as key attachment sites for muscles. Later ...
The lateral epicondyle of the humerus is a large, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow joint, and to a tendon common to the origin of the supinator and some of the extensor muscles.
