Omohyoid muscle the body of the hyoid bone, lateral to the insertion of the sternohyoid. The central tendon of this muscle varies much in length and form, and is held in position by a process of the deep cervical fascia, which sheaths it, and is prolonged down to be attached to the clavicle and first rib; it is by this means that the angular form of the muscle is maintained. The tendon overlies the internal jugular vein, and can be used as a landmark for this vein during surgery. Doubling; absence; origin from clavicle; absence or doubling of either belly. The inferior
Stylohyoid muscle and superior direction. Stylohyoid muscle The stylohyoid muscle is a slender muscle, lying anterior and superior of the posterior belly of the digastric muscle. It shares this muscle's innervation by the facial nerve, and functions to draw the hyoid bone backwards and elevate the tongue. Its origin is the styloid process of the temporal bone. It inserts on the body of the hyoid . It arises from the posterior and lateral surface of the styloid process of the temporal bone, near the base; and, passing inferior and anterior, it is inserted into the body of the hyoid bone, at its
