Question

in the classification of joints, which of the following is true?
immovable joints are called amphiarthroses.
all synovial joints are freely movable.
synarthrotic joints are slightly movable.
in cartilaginous joints, a joint cavity is present.
question 22 (1 point)
____ joints are classified as sutures, syndesmoses and gomphoses whereas ____ are classified as synchondroses and symphyses.
synovial; caritlaginous
cartilaginous; fibrous
fibrous; synovial
fibrous; cartilaginous

Explanation:

• For the first question:
• Immovable joints are called synarthroses, not amphiarthroses. Amphiarthroses are slightly movable joints.
• Synarthrotic joints are immovable.
• Cartilaginous joints do not have a joint cavity. Synovial joints have a joint cavity. And by definition, all synovial joints are freely movable.
• For the second question:
• Fibrous joints are classified as sutures (in the skull), syndesmoses (e.g., between tibia and fibula), and gomphoses (teeth in sockets).
• Cartilaginous joints are classified as synchondroses (e.g., epiphyseal plates in growing bones) and symphyses (e.g., pubic symphysis). Synovial joints have a different structure with a joint cavity, synovial membrane etc.

Answer:

• First question: All synovial joints are freely movable.
• Second question: Fibrous; Cartilaginous
