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…
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 Teres Major Muscle? The teres major is a broad muscle of the shoulder joint. It starts from the inferior aspect of the scapula to the proximal part of the humeral shaft. Unlike the teres minor, the teres major muscle will not attach to the glenohumeral joint capsule. Thus it is not considered as part of the rotator cuff muscles….
What is Sternocleidomastoid Muscle? The sternocleidomastoid muscle is a 2-headed neck muscle, true to its name bears joining to the manubrium of the sternum (Sterno), the clavicle (cleido), & the mastoid process of the temporal bone (mastoid). It is a lengthened, bilateral muscle of the neck, which functions to flex the neck both laterally & anteriorly, as well as rotate the head opposite…
What is Pectoralis Minor Muscle? The pectoralis minor muscle is triangular in shape & is located under the pectoralis major, & both formed the anterior wall of the axilla. The pectoralis minor muscle is one of the most surfaced muscles on the anterior aspect of the chest or thoracic wall, situated deeply only to the pectoralis major muscle. It is…
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…
What is Subscapularis Muscle ? The subscapularis is a triangular shoulder muscle situated in the subscapular fossa of the scapula. Attaching between the scapula & the proximal humerus, it is one of the 4 muscles of the rotator cuff, along with supraspinatus, infraspinatus, & teres minor. Rotator cuff muscles act to combine work for stabilization & steer the humeral head within the glenoid cavity during…
What is Supraspinatus Muscle? Supraspinatus is 1 of the rotator cuff muscles, along with infraspinatus, teres minor & subscapularis muscles. Supraspinatus is situated deeply to the trapezius muscle in the posterior scapular region, extending from the supraspinous fossa of the scapula to the proximal humerus. Together with the other rotator cuff muscles, supraspinatus work as a stabilization of the glenohumeral (shoulder) joint during the movements of the upper extremity. Additionally, it…
What is Latissimus dorsi Muscle? The latissimus dorsi muscle (‘the lats muscle’ or ‘the lats’) is the broadest muscle in the human body. It is relatively thin & covers almost all back muscles at the posterior trunk, rather than the trapezius muscle. Together with the levator scapulae, trapezius & rhomboid muscles, the latissimus dorsi relates to the superficial layer of the extrinsic…
What is Neck muscle tightness? Neck muscle tightening refers to the feeling of heaviness around the neck or tightness that occurs mainly in the posterior of the neck muscles. when the muscles in the neck will not fully relax, which will lead to soreness, muscle spasms, & headaches. It has more possible causes, ranging from…
