Figure 6–15. Types of joints. For each type, a specific joint is depicted, and a simple

diagram shows the position of the joint surfaces. (A) Ball and socket. (B) Hinge. (C) Pivot.

(D) Gliding. (E) Symphysis. (F) Saddle.

QUESTION:Which of these types of joints is most movable? Which is least movable?

Table 6–5 TYPES OF JOINTS

Category Type and Description Examples

Synarthrosis (immovable)

Amphiarthrosis (slightly

movable)

Diarthrosis (freely movable)

Suture—fibrous connective tissue

between bone surfaces

Symphysis—disc of fibrous cartilage

between bones

Ball and socket—movement in all

planes

Hinge—movement in one plane

Condyloid—movement in one plane

with some lateral movement

Pivot—rotation

Gliding—side-to-side movement

Saddle—movement in several planes
