Functions and Attachments of the Femur

Dr. Morton provides an in-depth overview of the femur, the principal bone of the thigh. The video covers the femur's anatomy, including the head, neck, greater and lesser trochanters, intertrochanteric line and crest, gluteal tuberosity, Linea Aspera, condyles, and the patellar surface. Key muscle attachments and joint articulations are highlighted, emphasizing the femur's role in movement and weight transmission.

What is the primary function of the femur in the human body?

• To support the weight of the upper body

• To aid in digestion

• To protect the internal organs

• To facilitate breathing

Which structure does the head of the femur articulate with?

• The patellar surface

• The tibial plateau

• The glenoid cavity

• The acetabulum of the os coxae

What is the significance of the greater trochanter?

• It serves as a site for muscle attachment

• It connects to the knee joint

• It protects the femoral artery

• It articulates with the tibia

Where do the iliopsoas muscles attach on the femur?

• Lesser trochanter

• Greater trochanter

• Gluteal tuberosity

• Intertrochanteric line

What is the function of the intertrochanteric line?

• It connects the femur to the tibia

• It serves as an attachment for the anterior joint capsule

• It supports the patella

• It articulates with the acetabulum

Which muscle attaches to the gluteal tuberosity?

• Rectus femoris

• Sartorius

• Biceps femoris

• Gluteus maximus

What is the role of the Linea Aspera?

• It supports the femoral artery

• It articulates with the patella

• It connects to the fibula

• It provides attachment for several thigh muscles

What is the function of the intercondylar notch?

• It supports the femoral artery

• It provides space for ligament attachment

• It articulates with the fibula

• It connects to the patella

Which ligament attaches to the medial epicondyle?

• Lateral collateral ligament

• Medial collateral ligament

• Anterior cruciate ligament

• Posterior cruciate ligament

What is the significance of the patellar surface?

• It is where the patella sits

• It connects to the fibula

• It supports the femoral artery

• It articulates with the acetabulum
