The subscapularis is covered by a dense fascia which attaches to the scapula at the margins of the subscapularis' attachment (origin) on the scapula. [1] The muscle's fibers pass laterally from its origin before coalescing into a tendon of insertion. [citation needed] The tendon intermingles with the glenohumeral (shoulder) joint capsule. [1]
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The lower subscapular nerve contains axons from the ventral rami of the C5 and C6 cervical spinal nerves. [2] [3] It is the third branch of the posterior cord of the brachial plexus.
The body's shape is determined by a strong skeleton made of bone and cartilage, surrounded by fat (adipose tissue), muscle, connective tissue, organs, and other structures. The spine at the back of the skeleton contains the flexible vertebral column , which surrounds the spinal cord , which is a collection of nerve fibres connecting the brain ...
Gross anatomy has become a key part of visual arts. Basic concepts of how muscles and bones function and deform with movement is key to drawing, painting or animating a human figure. Many books such as Human Anatomy for Artists: The Elements of Form, are written as a guide to drawing the human body anatomically correctly. [4]
The scapula is a thick, flat bone lying on the thoracic wall that provides an attachment for three groups of muscles: intrinsic, extrinsic, and stabilizing and rotating muscles. The intrinsic muscles of the scapula include the muscles of the rotator cuff (SITS muscle)—the subscapularis, supraspinatus , infraspinatus and teres minor. [ 3 ]
The scapulohumeral muscles are a group of seven muscles that connect the humerus to the scapula. They are amongst the muscles that act on and stabilise the glenohumeral joint in the human body. They include: coracobrachialis muscle deltoid muscle rotator cuff muscles: infraspinatus muscle subscapularis muscle supraspinatus muscle teres minor muscle teres major muscle See also Other muscles ...
The muscles shown are subscapularis muscle (at right), infraspinatus muscle (at top left), teres minor muscle (at bottom left) The movement of the scapula across the rib cage in relation to the humerus is known as the scapulohumeral rhythm , and this helps to achieve a further range of movement.
