2. WHO-DEY?! How did Carson Palmer’s knee injury impact his life?

3. Articulations
Dictionary definition: a joint in the body; a point of contact between two or more bones
Examples: ankle, knee, hip, shoulder, elbow, carpal, vertebral

4. Synovial Joints (freely moveable joints like the knee)
7 structures:
1. Joint Capsule: connective
tissue connecting bones on
the outside
2. Synovial Membrane: moist,
slippery membrane lining
the inner surface of the
joint capsule (lubricates
and nourishes surfaces)
3. Articular Cartilage:
connective tissue covering
joint surfaces of the bones

5. Synovial Joints Continued...
4. Joint Cavity: small space between bones allowing movement
5. Menisci: pads of cartilage located between the ends of bones which help prevent bones from grinding
6. Ligaments: strong cords of dense, white fibrous tissue connecting bones
7. Bursae: closed pillow-like structures filled with synovial fluid to cushion

6. Knee Joint AKA-tibiofemoral joint uniaxial, hinge joint
largest in the body
main weight bearing joint
very prone to injury because it is unprotected by surrounding muscle

7. Latin Prefixes ante- (anterior): in front of post- (posterior): behind
med- (medial): middle
lat- (lateral): side
cruc- (cruciate): cross
trans- (transverse): across
