Basic Joint Anatomy Worksheet

1.Why is there little to no movement in a fibrous joint?Because the bones making up the joint are united with strong fibrous tissue.

2.What is an example of a fibrous joint? sutures which hold the bones in the skull

3.Describe a cartilaginous joint and give an example. where bones are united by intervening fibrocartilage- vertebrae of the spinal column are joined by intervertebral discs

4.What type of joint essentially allows free movement? synovial joints

5. What lubricates a joint cavity? Synovial fluid.

6.For the following joint types please list the name of the joint type, the type of movement of the joint, the shape of the joint and an example.

7.Plane joint- synovial, gliding or slipping, slighlty curved articular surfaces, carpal bones in the hand

8.Hinge joint- synovial, movement is limited to rotate around a single axis, irregular cylinder and a concave groove, elbow joint

9.Condylar joint-synovial, similar to hinge but also as other movements, has 2 aticular surfaces, the knee joint

10.Ball and Socket joint- synovial, spherical articulation, movement in variety of directions, the shoulder joint

11.Ellipsoidal joint- synovial, oval ball and socket, variety of direct, wrist jointPivot joint- synovial, bony peg, rotate with respect to the other, joints between the radius and ulna

Saddle joint- synovial, 2 western saddles, articulating surfaces concave in one direction and convex in the other, movement in variety of directions, joint at base of the thumb.
