Stylohyoid muscle

From WikiMD's Wellness Encyclopedia

Stylohyoid muscle is a slender muscle in the human anatomy that belongs to the suprahyoid muscles group. It is named for its two attachments: the styloid process of the temporal bone and the hyoid bone.

Etymology[edit | edit source]

The term "stylohyoid" is derived from the Greek words "stylos" meaning pillar and "hyoeides" meaning shaped like the letter upsilon.

Structure[edit | edit source]

The stylohyoid muscle originates from the back of the styloid process of the temporal bone and inserts into the body of the hyoid bone. It is innervated by the facial nerve (cranial nerve VII).

Function[edit | edit source]

The primary function of the stylohyoid muscle is to elevate and retract the hyoid bone, aiding in swallowing and speech.

Clinical significance[edit | edit source]

Anomalies of the stylohyoid muscle can lead to a condition known as Eagle's syndrome, characterized by recurrent pain in the throat and difficulty swallowing.
