Styloid

Styloid

Styloid (pronounced: /ˈstaɪ.lɔɪd/) is a term used in anatomy to describe a long, slender, pointed structure. The term is derived from the Greek word "stylos", meaning pillar.

Etymology

The term "styloid" comes from the Greek word "stylos", which means pillar. This is due to the pillar-like shape of the structures that are referred to as styloid in the human body.

Anatomy

There are several structures in the human body that are referred to as styloid:

• Styloid process of the temporal bone: This is a thin, pointed piece of bone that extends down from the bottom of the temporal bone at the base of the skull. It serves as an attachment point for several muscles and ligaments of the neck.

• Styloid process of the ulna: This is a bony prominence found at the distal end of the ulna, one of the two bones in the forearm. It helps stabilize the wrist joint.

• Styloid process of the radius: This is a sharp, conical projection at the distal end of the radius, the other bone in the forearm. It is an important stabilizer of the wrist joint.

Related Terms

• Styloidectomy: This is a surgical procedure to remove a part of the styloid process when it is causing pain or discomfort, a condition known as Eagle's syndrome.

• Styloid ligament: This is a fibrous band that extends from the styloid process of the temporal bone to the lesser horn of the hyoid bone.

• Stylohyoid muscle: This is a small muscle that runs from the styloid process to the hyoid bone, and aids in swallowing and speech.
