What is Platysma Muscle? The platysma is a thin sheet-like muscle that is situated superficially within the anterior aspect of the neck. It begins in the upper thoracic & shoulder regions from a fascia that covers the pectoralis major & deltoid muscles. Its fibers ascend upper medially over the anterolateral aspect of the neck, to join to the mandible & the skin & subcutaneous tissue of the lower face. Unlike…
What are Infrahyoid Muscles? Infrahyoid muscles are also termed “strap muscles” which connect the hyoid, sternum, clavicle, & scapula. They are situated under the hyoid bone on the anterolateral surface of the thyroid gland & are involved in motions of the hyoid bone & thyroid cartilage during vocalization, swallowing, & mastication. They are composed of 4 paired muscles, organized into 2 layers as follows:…
What are Suprahyoid Muscles? There are numerous muscles in the neck. One of the classifications of the muscles of the neck is significant to the hyoid bone. Those muscles which are above the hyoid bone are termed supra-hyoid muscles, & those below it are known as infra-hyoid muscles. This group of muscles takes part in the…
Introduction The Adductor Brevis is the flat, triangular muscle that is found in the inner thigh. This muscle runs from the pubis to the medial aspect of the femur. Together with the adductor Longus, adductor Magnus, gracilis & pectineus muscles, it comprises a group of muscles called the adductor muscles of the thigh. These inner…
What is Teres Minor Muscle? Teres minor is a posterior muscle of the shoulder that enlarges between the scapula & the head of the humeral bone. It is one of the 4 muscles of the rotator cuff, along with the supraspinatus, infraspinatus, & subscapularis. Rotator cuff muscles act combine to control the movements of the humerus head & work as stabilizing it within the glenoid cavity…
What is adductor tendinopathy? Adductor tendinopathy describes a number of conditions that develop in & around of Adductor tendon in response to chronic overuse. At a histopathological level, there are changes in the molecular structure of the tendon, typically collagen separation & collagen degeneration & at a macroscopic level typically see tendon thickening, a loss…

What is Infraspinatus Muscle? The infraspinatus is a broad triangular muscle that takes the majority of the dorsal surface of the scapula. It arises mostly from the infraspinous fossa of the scapula,& joins it to the proximal humerus. The infraspinatus is one of the 4 rotator cuff muscles, alongside subscapularis, teres minor & supraspinatus muscles. As a portion of the rotator…
