STERNOHYOIDEUS Meaning and
Definition
-
The sternohyoideus refers to a specific muscle in the human body that is located in the neck region. It is part of the infrahyoid muscle group, which consists of several muscles situated below the hyoid bone. The word "sternohyoideus" is derived from its anatomical location and Latin origins, with "sterno" referring to the sternum and "hyoideus" pertaining to the hyoid bone.
The sternohyoideus muscle originates from the posterior surface of the medial end of the clavicle (collarbone) and extends upwards towards the body of the hyoid bone. It acts as a depressor muscle, aiding in the movement of the hyoid bone and larynx downwards. This muscle plays a crucial role in swallowing and speaking by regulating the movement and position of the hyoid bone during these functions.
It is important to note that the sternohyoideus muscle works in conjunction with other infrahyoid muscles, including the sternothyroideus, thyrohyoideus, and omohyoideus, to achieve its functions. The innervation of the sternohyoideus muscle is provided by the ansa cervicalis, which is a nerve structure formed by fibers from the first, second, and third cervical spinal nerves.
Understanding the anatomy and function of the sternohyoideus muscle is essential for medical professionals, particularly surgeons and speech therapists, in diagnosing and treating conditions related to the neck, swallowing difficulties, or speech disorders.

Etymology of STERNOHYOIDEUS
The word "sternohyoideus" is composed of two parts: "sterno-" and "hyoideus".
The prefix "sterno-" is derived from the Latin word "sternum", which refers to the breastbone, and is related to the Greek word "sternon". The sternum is a flat bone located in the center of the chest that connects the ribcage and provides support for the thoracic cavity.
The suffix "-hyoideus" is derived from the Greek word "hyoeidēs", which means "shaped like the letter upsilon (Υ)". In anatomy, "hyoid" refers to a U-shaped bone situated at the base of the tongue, between the jawbone and the larynx. It plays a crucial role in speech production, swallowing, and supporting the tongue.
