Ligments: the fibrous connective tissue that connects bones to bones.
Primary stabilizers
3 types
Capsular: capsule
Intra-capsule – inside joint capsule
Extra capsule – outside joint capsule
Fiber direction is specific to function
Slightly more elastin than tendons
Synovial joint: articulation of two bones surrounded by a joint capsule lined with synovial
membrane and lubricated with synovial fluid.
Ligaments provide primary stabilization and tendons cometimes provide dynamic stability.
The articulation ends of bones are lined with hyaline or artcular cartilage.
Fibrocartilage discs sometimes provide shock absorption and additional stability.
Bursae are pieces of synovial membrane that contain a small amount of fluid. Movement occurs
in one or more places
Peripheral nerve endings
Mechanoreceptors: provide information on proprioception.
Proprioception: the sense of relative position of neighboring parts of the body and
strength of effort in movement.
The unconsious perception of movement and spatial orientation arising from stimuli
within body.
Classification system:
1st degree ligament sprain signs and symptoms
Ligament damage: mild tearing
Point tenderness: yes
