What is an immovable joint that connects the bones of the skull?

• A. Suture
• B. Joint
• C. Syndesmosis
• D. Glenoid

Answer: (A)

Sutures are immovable fibrous joints that connect the bones of the skull. They are synarthroses, providing a strong, fixed connection to protect the brain. In infants, fontanelles are flexible areas that allow skull growth and passage during birth; as you grow, these areas ossify and the sutures become solid and essentially fuse shut. The other terms either describe joints in general or different types of connections (a syndesmosis is a fibrous joint with some movement, and the glenoid is a shoulder socket), so they don’t describe the skull’s immovable connections.
