8.14 The Femur
What are the seven surface structures found on the proximal epiphysis?
- Femoral head - Fovea capitis - Femoral neck - Greater trochanter - Lesser troachanter - Intertrochanteric line - Interochanteric crest
What are the names of the two bones that the femur articulates with?
- Hip bone - Tibia
What are the names of the two joints that the femur is involved with?
- Hip joint - Knee joint
What are the six surface structures on the distal epiphysis?
- Medial epicondyle - Lateral epicondyle - Medial condyle - Lateral condyle - Intercondylar fossa - Patellar surface
What are the three major regions that the femur can be divided into?
- Proximal epiphysis - Shaft - Distal epiphysis
What is the fovea capitis?
A small pit in the center of the femoral head
What is the function of the patellar surface?
Forms a smooth articular surface over which the patella glides
What is the function of the femoral head?
It articulates with the acetabulum of the hip bones
What is the function of the anterochanteric line?
It marks the edge of the articular capsule
What is the function of the femoral neck?
It separates the femoral head from the shaft of the femur
What is the function of the fovea capitis?
It serves as the attachment site for the ligament that connects the acetabelum to the femoral head
Is the greater trochanter considered medial or lateral when a person is in the anatomical position?
Lateral
What is a surface structure found on the shaft of the femur?
Linea aspera
Is the femoral head considered medial or lateral when a person is in the anatomical position?
Medial
Is the lesser trochanter considered medial or lateral when a person is in the anatomical position?
Medial
Where is the anterochanteric line located?
On the anterior surface of the proximal epiphysis
Where is the anterochanteric crest located?
On the posterior surface of the proximal epiphysis
What is the function of the greater and lesser trochanters?
Serve as attachment sites for large tendons
What is the function of the linea aspera?
Serves as an attachment site for the hip muscles
What are the two condyles separated by on the posterior side of the femur?
The intercondylar fossa
What are the two condyles separated by on the anterior side of the bone?
The patellar surface
What is the function of the medial and lateral condyles?
They form part of the knee joint
