Types of joints found in the human body: junction of two bones that permits movement.
Ribs and vertebrae = semi-mobile joints: ribs: bones of the thoracic cage. Vertebra: each of the bones of the spinal column. Semi-mobile joints: very restricted flexibility.
Vertebrae = cartilaginous joints: vertebra: each of the bones of the spinal column. Cartilaginous joints: flexibility due to cartilage, an elastic tissue.
Skull = immovable joints: skull: bony case of the brain. Fixed joints: joints that do not allow flexibility.
Elbow = hinged joint: elbow: joint connecting the forearm to the upper arm. Hinged joint: flexible in only one direction.
Hip = ball and socket joint: hip: part on the side of the body, between the waist and the top of the thigh. Ball and socket joint: flexibility due to a domed bone that turns in a cavity of the same shape.
