35
Head of femur
spherical head of femur articulates with os coxae at acetabulum
36
Neck of femur
located distal to the head, elongated and constricted; joins the shaft of the femur at an angle
37
Fovea capitis
small depression within head of femur
38
Trochanter - greater/lesser
two massive, rough processes originate near the proximal end of the femur and serve as insertion sites for gluteal and thigh muscles greater: projects laterally from junction of neck and shaft lesser: located on femur's posteromedial surface
39
Intertrochanteric crest (posterior)
where the greater and lesser trochanters are connected on the posterior surface of the femur; a thick oblique ridge of bone
40
Intertrochanteric line (anterior)
on anterior side, a raised line that extends between the two trochanters and marks the distal edge of the hip joint capsule
41
Gluteal tuberosity continues posteriorly as Linea aspera
gluteal tuberosity marks the attachment of the gluteus maximus muscle and merges proximally to the linea aspera, elevated midline ridge located on posterior surface of shaft

distal posterior surface of femur, deep fossa that separates the two condyles
45
Patellar surface
articular surface can be seen from posterior aspect and articulates with the patellar surface of the femur
46
Medial and lateral condyles of tibia
two relatively flat surfaces on broad superior head that articulate with the medial and lateral condyles of femur
47
Intercondylar eminence
prominent ridge that separates the medial and lateral condyles of tibia
48
Tibial tuberosity
rough anterior surface of the tibia near the medial and lateral condyles; can be palpated just inferior to the patella and marks the attachment site for the patellar ligament
49
Fibular notch of tibia
located on distal posterolateral side of tibia; where the fibula articulates and forms the inferior tibiofibular joint
50
Medial malleolus
a large prominent process at the medial border of tibia
51

distal tip that extends laterally to ankle joint
54
Base of patella
located superiorly and broad appearance on patella
55
Apex of patella
located inferiorly of base; pointed
56
