siniylev [52]

Answer:

Spinous process

Explanation:

The rhomboideus minor muscle originates on the <u>spinous processes</u> of vertebrae T2-T5

The rhomboideus minor muscle forms part of the superficial group of back muscles. The muscles in the superficial group are immediately deep to the skin and superficial fascia. They attach the superior part of the appendicular skeleton (clavicle, scapula, and humerus) to the axial skeleton (skull, ribs, and vertebral column).

These muscles are sometimes referred to as the appendicular group, since they are primarily involved with movements of part of the appendicular skeleton.

The rhomboideus minor is located deep to the trapezius in the superior part of the back. It inserts on the medial border of the scapula, is innervated by the dorsal scapular nerve its function is to adduct and elevate the scapula.
