In a study on iliotibial tract the tract was attached to the femur along the linea aspera from the greater tronchanter to and including the lateral epicondyle of the femur by coarse fibrous bands7 linea aspera has important prominence which protects the femur against bending when bearing the stresses and loads.

Function of linea aspera the main function of the la is the support and stabilization of the femur during walking and running as it serves as the attachment site of several muscles.

Linea aspera anatomy. This unlabeled quiz of the femur will test your knowledge on how to label the structures of this bone. Proximally the medial border of the linea aspera fits the pectineal line. Above the linea aspera is prolonged by three ridges.

The linea aspera is a longitudinally oriented ridge on the posterior aspect of the femur to which several muscles of the thigh attach. The lateral ridge is very rough and runs almost vertically upward to the base of the greater trochanter. The linea aspera is a prominent longitudinal ridge or crest on the middle third of the bone presenting a medial and a lateral lip and a narrow rough intermediate line.

You will be required to label the fovea capitis lateral epicondyle linea aspera intertrochanteric line intertrochanteric crest adductor tubercle greater trochanter lesser trochanter etc. Distally the linea aspera increases and forms the floor of the popliteal fossa the medial and lateral borders form the medial and lateral supracondylar lines. Femur quiz for anatomy and physiology.

Because of its involvement in daily activities la develops due to the use and strengthening of the muscles. The linea aspera is a prominent longitudinal ridge or crest on the middle third of the bone presenting a medial and a lateral lip and a narrow rough intermediate line. It is an important insertion point for the adductors and the lateral and medial intermuscular septa that divides the thigh into three compartments.

It is comprised of medial and lateral lips which diverge at both its superior and inferior ends. The lateral border enhances the gluteal tuberosity where the gluteus maximus attaches.
