Question

question 36

most of the bones of the skull are connected by immovable joints called ______.

a sinuses
b syndesmoses
c symphyses
d fissures
e sutures

Explanation:

Identify the core anatomical question

The question asks for the term that describes the immovable joints connecting most of the bones of the skull. This relates to Skeletal Anatomy and Joint Articulation.

Analyze the given options

• A. sinuses: Air-filled cavities within certain bones of the skull, not joints.
• B. syndesmoses: Slightly movable fibrous joints (amphiarthroses) where bones are joined by connective tissue ligaments (e.g., distal tibiofibular joint).
• C. symphyses: Cartilaginous joints where bones are joined by fibrocartilage (e.g., pubic symphysis).
• D. fissures: Narrow, slit-like openings between adjacent parts of bones through which blood vessels or nerves pass.
• E. sutures: Immovable fibrous joints (synarthroses) unique to the skull that tightly bind the skull bones together.

Determine the correct term

The immovable fibrous joints that connect the bones of the skull are anatomically defined as sutures.

Answer:

• (A) sinuses
• (B) syndesmoses
• (C) symphyses
• (D) fissures
• (E) sutures (Correct answer)
