Which of the Following Functional and Structural Characteristics are Associated

Question

Which of the following functional and structural characteristics are associated with each other?
A) synovial and diarthroses
B) cartilaginous and diarthroses
C) fibrous and diarthroses
D) synovial and synarthroses

Accepted Answer

Synovial joints are characterized by a synovial cavity and are classified as diarthroses, which are freely moveable joints. Therefore, synovial and diarthroses are associated with each other. 
Cartilaginous joints are typically amphiarthroses, which are slightly moveable, while fibrous joints are typically synarthroses, which are immovable. Therefore, B and C are not associated with each other. D is also incorrect because synovial joints and synarthroses are opposite types of joints.
