ANATOMY

Detailed explanation-1: -Functionally the three types of joints are synarthrosis (immovable), amphiarthrosis (slightly moveable), and diarthrosis (freely moveable). The two classification schemes correlate: synarthroses are fibrous, amphiarthroses are cartilaginous, and diarthroses are synovial.

Detailed explanation-2: -The three types of fibrous joints are sutures, syndesmoses, and gomphoses. Sutures are immobile joints in the cranium. The plate-like bones of the skull are slightly mobile at birth because of the connective tissue between them, termed fontanelles.

Detailed explanation-3: -There are three types of joints in the human body: fibrous, cartilaginous, and synovial. Fibrous joints are held together by dense connective tissue, cartilaginous joints are held together by cartilage, and synovial joints are free-moving and enclosed in a capsule.

Detailed explanation-4: -Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements. Hinge joints. Hinge joints, such as in the fingers, knees, elbows, and toes, allow only bending and straightening movements. Pivot joints.
