Superior longitudinal muscle of tongue Anatomy The superior longitudinal muscle is one of the intrinsic muscles of the tongue. It is responsible for various movements and changes in the shape of the tongue. The tongue is primarily composed of skeletal muscle, and the intrinsic muscles are responsible for its fine motor movements. origin : Insertion:…
Styloglossus Muscle Anatomy The styloglossus muscle is one of the intrinsic muscles of the tongue, playing a role in the movement and positioning of the tongue. It is part of a group of muscles responsible for the fine motor control of the tongue’s movements. The Styloglossus muscle is the shortest and smallest of the three…
Chondroglossus muscle: a muscle sometimes described as a part of the hyoglossus but is separated from it by fibers of the genioglossus, which pass to the side of the pharynx. One of the tongue’s muscles is the chondroglossus. It emerges from the hyoid bone’s medial side of the lesser horn before merging with the intrinsic…
The genioglossus muscle is a muscle of the tongue that plays a crucial role in various functions such as speech, swallowing, and breathing. The genioglossus is a bilateral tongue muscle that is in the part of the extrinsic muscles of the tongue. The palatoglossus, styloglossus, and hyoglossus (chondroglossus) are the additional extrinsic muscles of the…
Thyroarytenoid muscle is a broad, thin muscle that forms the body of the vocal fold and that supports the wall of the ventricle and its appendix. It functions to relax the vocal folds. It is part of the intrinsic musculature of the larynx and plays a crucial role in vocal production and control. origin :…
Arytenoid Muscle Anatomy Arytenoid muscle is a single muscle, that fills up the posterior concave surfaces of the arytenoid cartilages. The arytenoid muscle, also known as the interarytenoid muscle, is a composite intrinsic muscle of the larynx that is made up of two parts: an unpaired transverse arytenoid muscle and a bilaterally paired oblique arytenoid…
The cricothyroid muscle is the only tensor muscle of the larynx aiding with phonation. The cricothyroid muscle is a little muscle located deep in the anterior compartment of the neck that is bilaterally paired. It is one of the six intrinsic laryngeal muscles, along with the other six: The cricothyroid muscle’s primary job is to…
Salpingopharyngeus Muscle Anatomy The salpingopharyngeus muscle is a thin and elongated muscle located in the pharyngeal region of the human body. It is a component of the pharyngeal constrictor muscle group, which is essential to swallowing. Origin: Insertion: Nerve: Blood Supply The pharyngeal branch of the ascending pharyngeal artery, the larger palatine artery, and the…
Stylopharyngeus Muscle Anatomy The stylopharyngeus muscle is a long, slender muscle located in the pharynx, which is the muscular tube connecting the nasal and oral cavities to the larynx and esophagus. The stylopharyngeus is a muscle in the head that stretches between the temporal styloid process and the pharynx. The stylopharyngeus is a long, slender…
Shoulder Joint Anatomy ~The shoulder joint (glenohumeral joint) is a ball and socket joint between the scapula and the humerus. It is the major joint connecting the upper limb to the trunk. ~t is one of the most mobile joints in the human body, at the cost of joint stability. In this article, we shall…
