Supratragal Tubercle

The human supratragus muscle is divided into two sections: the upper, the supratragus muscle is the middle part, which starts from the lower edge on the anterior surface of the occipital bone, passes through the upper sections of the mastoid process, the anterolateral surface of the pyramid and ends in the cleft between the styloid process and the lesser horn of the hyoid bone or attaches to the lesser horn of the hyoid muscle. The middle section is called the lateral section, the narrow section has strong muscle tissue, starting from the temporal scales and elongated, limiting the parotid groove. The lower section is present in humans in the form of the temporomastoid muscle, which follows the lateral edge of the external auditory canal. Its other end is located on the upper part of the medial surface of the neck. In mammals, the three sections of the muscle change places: the middle section is a thin muscular tubercle, and the lateral section is thicker and larger. The upper section, which begins to spread along the entire length from the body of the brain stem to the pilot of the carious groove, is a continuation of the body of the corpus callosum connected to the parietal bone. The muscle is located on the opposite side
