A general term used to describe pain in muscles, tendons, bones, or joints.
symphysis
A fibrous amphiarthrosis, such as that between adjacent vertebrae or between the pubic bones of the coxal bones.
articular capsule
The dense collagen fiber sleeve that surrounds a joint and provides protection and stabilization; also called joint capsule.

flexion
A movement that decreases the angle between two articulating bones; the opposite of extension.
bursa

inversion
a turning inward
synovial fluid
The substance secreted by synovial membranes that lubricates joints.
intervertebral disc
A fibrocartilage pad between the bodies of successive vertebrae that absorbs shocks.
diarthrosis
a synovial joint
adduction
Movement toward the axis or midline of the body, as viewed in the anatomical position.
joint
An area where adjacent bones interact; also called articulation
suture
A fibrous joint between flat bones of the skull
meniscus
A fibrocartilage pad between opposing surfaces in a joint
dorsiflexion
Upward movement of the foot through flexion at the ankle
