Question

synarthrotic joints ______.

a - characterize all cartilaginous joints
b - have large joint cavities
c - are found only in adults
d - are immovable joints

Explanation:

Define synarthrotic joints

Synarthroses are functional classifications of joints. They are defined as immovable joints.

Evaluate option A

Cartilaginous joints can be synarthrotic or amphiarthrotic (slightly movable). They do not all share this single classification.

Evaluate option B

Synarthrotic joints lack a joint cavity. Large joint cavities are characteristic of diarthrotic (synovial) joints.

Evaluate option C

Synarthrotic joints, such as sutures in the skull, are present in infants and children, not only in adults.

Evaluate option D

By definition, synarthrotic joints are immovable joints. This matches the functional definition of a synarthrosis.

Answer:

• (A) characterize all cartilaginous joints
• (B) have large joint cavities
• (C) are found only in adults
• (D) are immovable joints (Correct answer)
