Supraspinatus Muscle Anatomy The supraspinatus is a relatively small muscle of the upper back that runs from the supraspinatous fossa superior portion of the scapula (shoulder blade) to the greater tubercle of the humerus. Supraspinatus with the other three muscles join to grouping rotator cuff and abduction of the shoulder joint is done. The spine…
Rhomboid Major Muscle Anatomy The Rhomboid major muscle is a skeletal muscle on the back that connects the scapula with the vertebrae of the spinal column. In human anatomy, it acts together with the rhomboid minor to keep the scapula pressed against thoracic wall and to retract the scapula toward the vertebral column. Origin :…

It is situated at the back and the side of the neck, and as its name suggests – its main function is to lift the scapula. The position of the muscle defines its supportive role in the vertebral column….
