The rhomboid muscles are a pair of muscles located in the upper back region. They are primarily responsible for retracting the scapulae (shoulder blades), which means pulling them together towards the spine. Major and minor rhomboids comprise the rhomboids, a collective group of muscles. The stability of the scapula the shoulder girdle and all upper limb movements…
The longus capitis muscle is one of the four deep muscles of the anterior neck. It originates from the transverse processes of the third to the sixth cervical vertebrae and inserts onto the basilar part of the occipital bone. What Is The Longus Capitis Muscle? A deep anterior neck muscle that runs in front of…
The extensor carpi ulnaris muscle is a prominent anatomical structure located in the forearm, essential for various t is situated on the ulnar side of the forearm, running along the posterior aspect. The posterior edge of the ulna and the lateral epicondyle of the humerus are the origins of this muscle. It extends distally, inserting…
The serratus anterior muscle is a crucial anatomical structure located on the lateral aspect of the rib cage, extending from the first to ninth ribs. Often referred to as the “boxer’s muscle” due to its prominence in fighters, this muscle plays a vital role in various arm and shoulder movements, contributing significantly to upper body…
The levator scapulae muscle is a key anatomical structure located in the posterior region of the neck. As its name suggests, this muscle is responsible for elevating the scapula, or shoulder blade, hence playing a crucial role in shoulder movement and stabilization. What Are Levator Scapulae Muscles? The levator scapulae can extend and laterally flex…
The pronator teres muscle is a key anatomical structure located in the forearm region of the upper limb. It plays a vital role in forearm pronation, which is the movement of turning the palm downwards or towards the posterior aspect of the forearm. This muscle is part of the superficial layer of the anterior compartment…
The brachioradialis muscle is a forearm muscle that plays a significant role in both the flexion and extension of the forearm. It is located on the lateral side of the forearm, running from the distal end of the humerus (upper arm bone) down to the radius (one of the two bones of the forearm). Additionally,…
The sternocleidomastoid muscle, often abbreviated as SCM, is a prominent muscle located in the neck. Its name is derived from its points of origin and insertion: the sternum (sterno-), clavicle (cleido-), and mastoid process of the temporal bone (mastoid). This large, superficial muscle plays a crucial role in various head movements, including rotation, flexion, and…
The large, flat latissimus dorsi muscle occupies the majority of the lower posterior thorax. Although the muscle’s main job is to move the upper limb, it also serves as an auxiliary muscle for breathing. Owing to this muscle’s extensive attachment to the thoracolumbar fascia and several vertebral spinous processes, research on the muscle’s function in…
The teres minor muscle is a small yet vital muscle located in the posterior shoulder region. Together with the infraspinatus muscle, it forms part of the rotator cuff, a group of muscles and tendons crucial for stabilizing and providing mobility to the shoulder joint. The rotator cuff’s teres minor is an elongated, thin muscle. The…
