The sternocleidomastoid muscle originates from two locations: the manubrium of the sternum and the clavicle. [4] It travels obliquely across the side of the neck and inserts at the mastoid process of the temporal bone of the skull by a thin aponeurosis. [4] [5] The sternocleidomastoid is thick and narrow at its center, and broader and thinner ...
Anatomical terms of bone. [edit on Wikidata] The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Its rough surface gives attachment to various muscles (via tendons) and it has openings for blood vessels. From its borders, the mastoid part articulates with two other bones.
Conservative, surgical excision. A branchial cleft cyst or simply branchial cyst is a cyst as a swelling in the upper part of neck anterior to sternocleidomastoid. It can, but does not necessarily, have an opening to the skin surface, called a fistula. The cause is usually a developmental abnormality arising in the early prenatal period ...
The platysma muscle is a broad sheet of muscle arising from the fascia covering the upper parts of the pectoralis major muscle and deltoid muscle. Its fibers cross the clavicle, and proceed obliquely upward and medially along the side of the neck. This leaves the inferior part of the neck in the midline deficient of significant muscle cover.

The lower sternocleidomastoid branch passes infero-external to the hypoglossal nerve before descending into the substance of the muscle to which its name is derived. The upper sternocleidomastoid branch diverts from the main trunk at the deep border of the proximal end of the posterior digastric muscle belly, coursing with the spinal accessory ...
Superficial dissection of the left side of the neck, showing the carotid and subclavian arteries. The fascia and middle thyroid veins. (Superior thyroid artery labelled at upper left.) The superior thyroid artery arises from the external carotid artery just below the level of the greater cornu of the hyoid bone and ends in the thyroid gland.
Myofascial pain is associated with muscle tenderness that arises from trigger points, focal points of tenderness, a few millimeters in diameter, found at multiple sites in a muscle and the fascia of muscle tissue. Biopsy tests found that trigger points were hyperirritable and electrically active muscle spindles in general muscle tissue.
Sternocleidomastoid branch may refer to: Sternocleidomastoid branch of superior thyroid artery; Sternocleidomastoid branches of occipital artery
