Question 20

Greater Trochanter

Answer 20

D
Location: Large, lateral prominence on the proximal femur
Attachments: Gluteus medius, gluteus minimus, piriformis, and other hip muscles
Other info: Palpable, sits on the same plane as the symphisis pubis
(GT = falling off the mattress in the tent, very sore)

Question 21

Angle of Inclination

Answer 21

Where the femoral neck joints the shaft at an angle of approximately 125º

Question 22

Neck of the Femur

Answer 22

C
Location: Narrow region connecting the head to the shaft

Question 24

Fovea

Answer 24

A
Location: A small depression in the head of the femur
