Ok, Let’s review
joints in a little
more detail
Types of Synovial Joints
Ball-and-Socket Joint
• hip
• shoulder
Condyloid Joint
• between metacarpals
and phalanges
8-9
Types of Synovial Joints
Gliding Joint

• between tarsals
Hinge Joint
• elbow
• between phalanges
8-10
Types of Synovial Joints
Pivot Joint
• between proximal
ends of radius and
ulna
Saddle Joint
• between carpal and
metacarpal of thumb
8-11
Sprain: injury to ligament
Strain: injury to muscle or tendon
Synovial Joints: Friction-Reducing
Structures
• Bursae – flattened, fibrous sacs lined with
synovial membranes and containing synovial
fluid
• Common where ligaments, muscles, skin,
tendons, or bones rub together
• Tendon sheath – elongated bursa that wraps
completely around a tendon

encircles the shoulder joint and blends
with the articular capsule
