Joint Classification
What are the three structural classifications of joints?
Fibrous, cartilaginous, synovial
What fluid lubricates synovial joints?
Synovial fluid
Which joint type allows rotation (e.g., neck)?
Pivot
What movement decreases the angle between bones?
Flexion
What is a sprain?
Ligament injury
Which type of joint is immovable?
Synarthrosis
What structure encloses the joint cavity?
Joint capsule
What joint is found in the elbow?
Hinge
What movement increases the angle between bones?
Extension
What is arthritis?
Joint Inflammation
What type of joint allows slight movement?
Amphiarthrosis
What is the function of articular cartilage?
Reduces friction / absorbs shock
Which joint allows movement in all directions (shoulder)?
Ball and Socket
What is rotation?
Movement around an axis
Which type of arthritis is wear-and-tear?
Osteoarthritis
What classification includes joints with a joint cavity?
Synovial
What produces synovial fluid?
Synovial membrane
What type of joint is the wrist?
Condyloid
What movement moves a limb away from midline?
Abduction
What happens in a dislocation?
Bone forced out of joint
What is the functional classification of a freely movable joint?
Diarthrosis
What is the role of bursae in joints?
Reduce friction between tissues
Which joint type allows gliding movements (carpals)?
Plane (gliding)
What is circumduction?
Circular Movement
What is the difference between a sprain and strain?
Sprain = ligament, Strain = muscle/tendon
