Question

what is the functional classification of the intervertebral disc joint?
answers: a - e
a synovial
b diarthrosis
c fibrous
d amphiarthrosis
e synarthrosis

Explanation:

Amphiarthrosis joints allow a small amount of movement. Intervertebral disc joints fall into this category as they permit limited motion between vertebrae. Synovial (A) and fibrous (C) are structural classifications, not functional. Diarthrosis (B) is a freely movable joint (e.g., shoulder), and synarthrosis (E) is immovable (e.g., skull sutures).

Answer:

D. Amphiarthrosis
