It is situated in the tympanic cavity in the middle ear, connecting the pyramidal eminence of the petrous part of the temporal bone to the posterior aspect of the neck of stapes. its purpose is to stabilize the smallest…
Introduction The sternohyoid muscle is a flat muscle located on both sides of the neck.The sternohyoid muscle is a strap-like infrahyoid muscle that connects the hyoid bone with the clavicle and sternum. Along with the omohyoid muscle, it comprises the superficial plane of infrahyoid muscles, while the sternothyroid and thyrohyoid muscles belong to the deep…
Introduction The stylohyoid muscle is a paired muscle located in the anterior triangle of the neck.Stylohyoid muscle is a small slender muscle, that lies on the upper border of the posterior digastric muscle. It is part of the suprahyoid group of the muscle which connects the hyoid bone to the mandible and skull. There is…
Introduction Geniohyoid muscle is a short and narrow muscle that lies above the medial part of the mylohyoid muscles. The Geniohyoid muscle is a short, paired muscle that belongs to the suprahyoid muscle group of the neck. Together with the digastric, stylohyoid, and mylohyoid muscles, it makes the floor of the oral cavity. The geniohyoid…
Introduction of the Spinalis Cervicis The Spinalis group of the muscle is part of the erector spinae (ES) group (the intermediate layer of the intrinsic back muscles). Spinalis Cervicis muscle is the cervical portion of the spinalis muscle with spinalis capitis muscle superiorly and spinalis thoracis muscle inferiorly.The Spinalis Cervicis muscle is variably present. Origin:…
Introduction of the suprahyoid muscles The suprahyoid muscles are the digastric, the stylohyoid, the mylohyoid, and the geniohyoid. They all are pharyngeal muscles, with the exception of the geniohyoid muscle.They are described below. The digastric muscle The digastric muscle lies below the body of the mandible, and extends, in a curved form, from the mastoid…
