A lot of the upper back muscles use a scapula for support.
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.
Protraction of the scapula, produced by actions of both the serratus anterior and pectoralis minor muscles.
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.
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.

Most originate on the Scapula (the Shoulder Girdle), not all though. The Pectoralis Major & Minor and the Latissimus Dorsi do not.
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.
Your scapula is your shoulder-blade. The scapula only connects at the clavicle and is held in place by muscles.
Function of the ScapulaThe scapula is the mobile bone to which most of the shoulder muscles are attached. It is attached to the back by other muscles. It serves as a broad plate for the strong anchoring of muscles of the upper extremity.
Pectoralis Minor

Pectoralis Major
It is the shoulder blade. It connects the arm bone to the collar bone. It connects to many shoulder muscles to move your arms and shoulders.
Many muscles are attached to shoulder girdle. You have trapezius, deltoid muscles attached to spine of the scapula and clavicle. Rhomboid major and minor muscles and serratus anterior muscle attached to the medial border of the scapula. You have subscapularis, supraspinatus, infraspinatus muscles attached to the inner and outer surfaces of the scapula. You have teres minor and major muscles attached to lateral border of the scapula. You have pectoralis major muscle (clavicular head) attached to clavicle. You have biceps muscle attached to coracoid process and supraglenoid tubercle of the scapula. you have long head of triceps attached to infraglenoid tubercle of the scapula. you have pectoralis major muscle attached to coracoid process of the scapula.You have subclavius muscle attached to clavicle.
The main function of the shoulder blade is that it is an attachment area for many muscles. Some of the muscles include the Pectoralis Minor, Coracobrachialis, and Serratus Anterior.
