Biceps brachii muscle Anatomy Biceps brachii is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. Both heads arise on the scapula and join to form a single muscle belly which is attached to the upper forearm. “Capulets breve” is another term for the short head, and “capulets longum”…
Coracobrachialis Muscle Anatomy The coracobrachialis muscle is the smallest of the three muscles that start from the coracoid process of the scapula. It is located at the upper and medial part of the arm (superomedial part of the humerus- Anterior Compartment of the Arm). Muscle details The contraction of the coracobrachialis leads to two movements…
Subscapularis Muscle Anatomy A large triangular-shaped muscle which fills the subscapular fossa. The term “subscapularis” means under (sub) the scapula. It is largest and strongest muscle of the rotator cuff muscle. Origin It originates from the medial two-thirds of the subscapular fossa. Insertion It inserts into the lesser tubercle of the humerus and the front…
Teres major Muscle Anatomy The teres major muscle is one of the six muscles within the scapulohumeral muscle group. This muscle is commonly confused as a rotator cuff muscle, but it is not because it does not attach to the capsule of the shoulder joint, unlike the teres minor muscle. Origin : It originates from…
Teres Minor Muscle Anatomy The teres minor is a slim, narrow muscle within the rotator cuff, located in the shoulder. It also contributes to the rotator cuff, a capsule of muscles and tendons that collectively stabilize the glenohumeral joint. Origin It originates from the lateral border and adjacent posterior surface of the scapula. Insertion It…
Muscle details : The infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa. It is one of the muscles of rotator cuff. Origin : It originates from the medial two -thirds of the infraspinous fossa of the scapula . Insertion : It inserts into the middle impression on…
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 Minor Muscle Anatomy The Rhomboid minor is a small skeletal muscle on the back that connects the scapula with the vertebrae of the spinal column. Along with the Rhomboid major, it keeps the scapulae pressed against the thoracic wall. Origin It originates from, Insertion It inserts into a small area of the medial border…
What is an Interferential Therapy (IFT)? ~Interferential therapy is a type of electrical stimulation that uses four surface electrodes (two pairs of electrodes) that are placed in an “X” pattern surrounding a painful area that deliver two separate pulsed, high-frequency signals. One pulsed signal, typically around 4000 Hz, is delivered between one pair of electrodes….
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 :…
