Ball-and-socket joints, found in the hips and shoulders, allow movement across multiple planes, including rotational movement.
Pytanie 5: Which bone does not articulate directly with any other bone in the body?
Poprawna odpowiedź: CHyoid bone
The hyoid bone is suspended by muscles and ligaments in the neck and serves as an anchoring structure for the tongue.
Pytanie 6: What is the primary role of osteoclasts in bone biology?
Poprawna odpowiedź: BBreaking down bone tissue
Osteoclasts dissolve old or damaged bone matrix during remodeling, whereas osteoblasts build new bone tissue.
Pytanie 7: How many vertebrae make up the normal adult cervical spine?
Poprawna odpowiedź: B7
The human neck contains 7 cervical vertebrae, labeled C1 through C7, which support the skull and permit head rotation.
Pytanie 8: What tissue covers the ends of bones where they meet to form movable joints?
Poprawna odpowiedź: BHyaline cartilage
Hyaline cartilage, specifically articular cartilage, provides a smooth, low-friction surface that absorbs shock within synovial joints.
Pytanie 9: Which anatomical structure produces red blood cells within long and flat bones?
Poprawna odpowiedź: ARed bone marrow
Hematopoiesis occurs in red bone marrow, while yellow bone marrow is composed primarily of fat cells that store energy.
Pytanie 10: Which pair of bones forms the human forearm?
Poprawna odpowiedź: BRadius and ulna
