Femur
- Head of Femur - rounded, proximal end of the femur; articulates with the acetabulum of the hip bone to form the hip joint
- Neck of Femur - narrowed region inferior to the head of femur; a common area for fractures
- Linea Aspera - a roughened ridge; passes distally along the posterior surface of the mid-femur; place of attachment for multiple muscles of the hip and thigh
- Greater Trochanter - a large, upward projection located above the base of the neck; can be felt just under the skin on the lateral side of the upper thigh
- Lesser Trochanter - a small prominence located on the medial surface of the femur, just below the neck.
- Intercondylar Notch (or fossa) - a notch on the posteroinferior surface of the distal femur between the medial and lateral condyles of the femur
- Lateral Condyle - a projection on the lateral surface of the femur at its distal end; more prominent
- Medial Condyle - a projection on the medial surface of femur at its distal end; less prominent
- Lateral Epicondyle - a small, tuberculated eminence on the lateral surface of femur at its distal end; above the lateral condyle; less prominent than the medial epicondyle; attachment for the fibular collateral ligament of the knee-joint
- Medial Epicondyle - a larger tuberculated eminence on the medial side of the femur at its distal end; above the medial condyle
- Intertrochanteric Crest - a ridge that marks the transition between the neck of the femur and the shaft of the femur; located on the posterior surface of the head of the femur; stretches obliquely downward and medially from the greater to the lesser trochanter
- Intertrochanteric Line - a ridge that marks the transition between the neck of the femur and the shaft of the femur; located on the anterior surface of the head of the femur; stretches from the greater to the lesser trochanter
Tibia
- Tibial Tuberosity - an elevation on the proximal, anterior aspect of the tibia, inferior to where the anterior surfaces of the lateral and medial tibial condyles end.
- Anterior Crest - a prominence that begins at the tuberosity and ends at the anterior margin of the medial malleolus; it is sinuous and prominent in the upper two-thirds, but smooth and rounded below
- Medial Malleolus - a prominence on the medial side of the ankle, formed by the lower end of the tibia.
- Intercondylar Eminence - composed of the medial and lateral intercondylar tubercle; divides the intercondylar area (the separation between the medial and lateral condyle located toward the proximal portion of the tibia) into anterior and posterior part.
Fibula
- Head of Fibula - the small, knob-like, proximal end of the fibula; articulates with the inferior aspect of the lateral tibial condyle to form the proximal tibiofibular joint
- Lateral Malleolus - a prominence on the lateral side of the ankle, formed by the lower end of the fibula.
Patella - also known as the kneecap; a flat, rounded triangular bone which articulates with the femur and covers and protects the anterior articular surface of the knee joint.
Tarsals - a set of seven irregularly shaped bones; located distally to the leg and proximally to the metatarsals
Metatarsals - a set of five bones, connect the phalanges to the tarsals.
Phalanges - bones of the toes; each toe has three phalanges – proximal, intermediate, and distal (except the big toe, which only has two phalanges).
