Study Notes
Elbow Joint
- Hinge joint
- Involves the humerus, radius, and ulna
Joints of the Elbow
- Humero-ulnar joint
- Largest and strongest joint at the elbow
- Between the trochlea of the humerus and the trochlear notch of the ulna
- Limited movement
- Humeroradial joint
- Smaller joint
- Between the capitulum of the humerus and the head of the radius
Structures of the Elbow
- Biceps brachii muscle
- Attaches to the radial tuberosity
- Controls elbow motion
- Elbow ligaments
- Radial collateral
- Anular
- Ulnar collateral
Knee Joint
- Complex hinge joint
- Transfers weight from the femur to the tibia
- Three articulations
- Two femur-tibia articulations (at the medial and lateral condyles)
- One between the patella and patellar surface of the femur
Knee Joint Capsule and Structures
- Joint capsule and joint cavity of knee
- Medial and lateral menisci
- Fibrocartilage pads
- Cushion and stabilize the joint
Supporting Ligaments of the Knee
- Seven major supporting ligaments
- Patellar ligament (anterior)
- Two popliteal ligaments (posterior)
- Anterior and posterior cruciate ligaments (inside joint capsule)
- Tibial collateral ligament (medial)
- Fibular collateral ligament (lateral)
