MUSCULUS CLEIDOMASTOIDEUS Meaning and
Definition
-
The musculus cleidomastoideus, commonly referred to as the sternocleidomastoid muscle, is a vital muscle found in the neck region of the human body. It is a paired muscle, with one located on each side of the neck. The term "musculus cleidomastoideus" is chiefly used in the anatomical context.
The sternocleidomastoid muscle originates from two specific points on the chest wall: the top of the sternum (sterno-) and the clavicle (-cleidomastoid). It then extends upwards toward the base of the skull (mastoid process). This muscle can be easily identified, as it forms a distinct diagonal division along the anterior-lateral portion of the neck.
The muscle plays a significant role in the movement of the head and neck. When only one side contracts, it slightly rotates the face towards the opposite direction and tilts the head sideways. However, when both sides are activated, it causes bilateral neck flexion or forwards bending of the neck. Additionally, the sternocleidomastoid muscle aids in the elevation of the ribcage during deep inhalation.
Despite its apparent anatomic implications, the sternocleidomastoid muscle also has clinical significance. It serves as an essential landmark for various medical procedures in the neck region, such as injections or surgical interventions. Furthermore, certain medical conditions can affect the functioning of this muscle, resulting in decreased range of motion or contracture, which can lead to restricted head and neck motion, pain, or cosmetic abnormalities.

Etymology of MUSCULUS CLEIDOMASTOIDEUS
The term "musculus cleidomastoideus" is a combination of Latin and Greek words.
1. "Musculus" comes from the Latin word for "muscle".
2. "Cleido" is derived from the Greek word "kleis" meaning "clavicle" or "collarbone".
3. "Mastoideus" comes from the Greek word "mastoidēs" meaning "breast-shaped" or "breast-like" due to its shape resembling a female breast.
So, "musculus cleidomastoideus" can be translated as the "muscle of the collarbone-breast shape" or "muscle of the collarbone-breast-like shape". This term is used to refer to the sternocleidomastoid muscle, which is a paired muscle located in the neck.
