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 :…
Levator scapulae Muscle Anatomy The levator scapulae muscle is a long muscle of the shoulder girdle. 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….
Latissimus dorsi Muscle Anatomy Latissimus Dorsi is a large, flat triangular muscle that covers a large area of the lower back and is overlapped by the trapezius. It is also known as the Broadest muscle of the back. The muscle runs between the trunk, via an extensive attachment and the humerus by a narrow tendon….
Trapezius Muscle Anatomy The trapezius (or trapezoid) is a large paired surface muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae of the spine and laterally to the spine of the scapula. It moves the scapula and supports the arm. The descending (superior), ascending (inferior), and middle sections make up the…
Subclavius Muscle Anatomy The subclavius is a small triangular muscle, placed between the clavicle and the first rib. Along with the pectoralis major and pectoralis minor muscles, the subclavius muscle makes up the anterior wall of the axilla. Origin The subclavius muscle originates from the first rib. Specifically, this muscle begins in the area between…
Pectoralis minor muscle Anatomy The pectoralis minor muscle is triangular in shape and is located under the pectoralis major, and both form the anterior wall of the axilla. Origin It originates from the, Insertion It inserts on the medial border and upper surface of the coracoid process. Nerve supply It is supplied by the medial…
