How Do You Spell STERNOCLEIDOMASTOID?

1. The sternocleidomastoid is a prominent muscle located in the front of the neck on both sides. Its name is derived from the Latin terms "sternum" for breastbone, "cleido" for clavicle, and "mastoid" for a bony prominence behind the ear. This muscle is unique in that it has two distinct attachments and actions.

   Originating from the sternum and clavicle, the sternocleidomastoid muscle has a narrow, elongated shape. It then ascends vertically on each side of the neck toward the head, where it inserts into the mastoid process of the temporal bone.

   The primary function of the sternocleidomastoid muscle is to rotate and tilt the head. When only one side is contracted, it causes ipsilateral rotation of the head and contralateral tilt. Simultaneous contraction of both sides flexes the neck forward. Additionally, this muscle aids in elevating the sternum during forced inhalation.

   The sternocleidomastoid muscle is innervated by the accessory nerve (cranial nerve XI) and receives blood supply from the superior thyroid artery. It is an important landmark for medical professionals to evaluate neck pathology as it is visible and palpable. Swelling or muscle tension in this area can indicate injury, inflammation, or other underlying conditions.

2. Relating to sternum, clavicle, and mastoid process, noting the origins and insertion of the muscle so named.
