The lower limb Flashcards
What is the sacral promontory?
Where L5 meets S1
Where does the head of the femur go into?
Acetabulum
Why is extension of the leg limited?
Because of the ligaments and their fibers direction
What happens to the ischiofemoral ligament during flexion?
They are completely relaxed
What can be used to distinguish left and right femur?
The head as it looks medial
What is the area on the back of the knees called?
The popliteal region
Are the condyles at the end of the femur large or small?
Large
Why are the condyles of the femur more developed/rounded on the posterior side?
Flexion of the knee is much more extended than extension so there is need for more surface of the condyle of the posterior
What can vary a lot from person to person in the femur?

Coxa vara
Latin name for hip
Coxa
What effect does the angle of the head of the femur have?
