- A A joint type that largely lacks any fluid-filled cavity between its two articulating bone surfaces, unlike most movable joints in routine practice overall in most cases under typical conditions
- B Articular cartilage covers bone ends; synovial cavity contains synovial fluid; synovial membrane lines the joint capsule; fibrous joint capsule and ligaments stabilize the joint
- C Two bones that are permanently fused directly together by largely ossified, rigid connective tissue with little movement possible according to standard textbooks in general practice
- D Mainly a thin layer of articular cartilage is present at this joint, with very little synovial fluid contained inside the cavity as frequently described in most textbook accounts
Correct answer: B. Articular cartilage covers bone ends; synovial cavity contains synovial fluid; synovial membrane lines the joint capsule; fibrous joint capsule and ligaments stabilize the joint
Explanation: Synovial joint structure: bone ends covered by hyaline articular cartilage (reduces friction); joint cavity filled with synovial fluid; synovial membrane (secretes fluid) lines inner capsule; outer fibrous capsule reinforced by ligaments. Bursae (fluid sacs) may reduce friction between tendons and bone.
