Stylohyoid
Stylohyoid
Stylohyoid (pronounced: sti-lo-hi-oid) is a term used in anatomy to refer to a slender muscle located in the neck. It is one of the muscles involved in the hyoid bone complex, which plays a crucial role in swallowing and speech.
Etymology
The term "Stylohyoid" is derived from the Greek words "stylos," meaning pillar, and "hyoeides," meaning shaped like the letter upsilon. This is in reference to the muscle's location and function, connecting the styloid process of the temporal bone to the hyoid bone.
Function
The Stylohyoid muscle functions to elevate and retract the hyoid bone, aiding in swallowing and speech. It is innervated by the facial nerve (cranial nerve VII).
