Sternocleidomastoid Branch

Greeting is a part of every person's daily life, but what do we know about it and its branches?

The sternocleidomastoid branch (SGMA) is classified as a thyroglossal branch that arises from the ascending cervical artery. GRKVSV ​​is formed by its departure from the anterolateral wall of the lateral part of the external carotid artery. It runs down over the mastoid process in the inversion near the midline of the neck. On its way, it gives off two branches: the posterior and anterior cardiac branches, the upper cutaneous branch, as well as the branch that innervates the anterior teeth and upper cervical lymph nodes. The humerus is attached to the upper depths of the clavicle.

The sternocleidomastoid branch is located in the neck and connects the sternum and clavicle. It is a long branch of the side of the neck. Its continuation is the dorsal part of the ear. The sternocleidomastoid branches are represented by two muscles - ventral and dorsal. Muscle fibers determine the different location and structure of the sternocleidomastical branch. Muscles may be smooth or discontinuous. In the anterior part of the sternoclavicular branch there is a bundle of the sternal nerve and a large thyroid gland. The interosseous vein can arise from this branch; it participates in the development of the cervical artery, which is classified as a subclass of bone marrow branches. Most often, the thoracic sternum touches other parts of the neck.
