The nurse is caring for a patient in the emergency department with an injured shoulder. Which type of joint will the nurse assess?

A) Fibrous
B) Synovial
C) Synergistic
D) Cartilaginous

Synovial joints, or true joints, such as the hinge type at the elbow, are freely movable and the most mobile, numerous, and anatomically complex body joints. Fibrous joints fit closely together and are fixed, permitting little, if any, movement such as the syndesmosis between the tibia and the fibula. Synergistic is a type of muscle, not joint. Cartilaginous joints have little movement but are elastic and use cartilage to unite separate bony surfaces such as the synchondrosis that attaches the ribs to the costal cartilage.
