What is the Job and function of the scapula?
The scapula, also known as the shoulder blade, is a flat bone located on the upper back. Its main function is to provide attachment points for muscles that control shoulder movement, such as the deltoid and rotator cuff muscles. Additionally, the scapula helps stabilize and support the shoulder joint, allowing for a wide range of arm movements.
The vertebral column is what to the scapula?
It is inserted into the medial border of the scapula, between the superior angle and the triangular smooth surface at the apex of the spine. THE MUSCLES CONNECTING THE UPPER LIMB WITH THE VERTEBRAL COLUMN.
What structure does the scapula move upon?
The scapula moves against the posterior aspect of the rib cage. There is also articulation of the scapula with the humerous at the glenoid fosa and with the clavical at the acromion.
How does serratus anterior function as an antagonist to the rhomboideus muscles?
The serratus anterior is responsible for the protraction of the scapula. It pulls the scapula forward and around the rib cage, like when someone throws a punch. Often referred to as the "boxer's muscle". It is also responsible for stabilizing the scapula and assisting in its rotation upward.
Bone that has an acromion and spine?
The acromion is the part of the scapula or shoulder blade that forms the tip of the shoulder. The acromion is an anatomical feature on the shoulder blade (scapula), together with the coracoid process extending laterally over the shoulder joint.

What do muscles that act on the shoulder originate?
Most originate on the Scapula (the Shoulder Girdle), not all though. The Pectoralis Major & Minor and the Latissimus Dorsi do not.
What is the origin and insertion of the shoulder muscles?
The shoulder muscles originate from the scapula (shoulder blade) and the clavicle (collarbone) and insert into the humerus (upper arm bone).
What bone do the muscles of the rotator cuff originate?
The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
