What is the anatomy of the femur?

femur, also called thighbone, upper bone of the leg or hind leg. The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament (ligamentum teres femoris) within the socket and by strong surrounding ligaments. The femur is the only bone in the thigh and the longest bone in the body. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal. In this article, we shall look at the anatomy of the femur – its attachments, bony landmarks, and clinical correlations. Two extremities of femur bone Femur bone articulates with hip bone above and form hip joint in animal. Again this bone articulates with tibia, fibula and patella below and form the stifle joint.The depression between the condyles is called the patellar groove. Inside the body of the femur is the medullary cavity, which contains bone marrow. At the ends of the femur are areas of compact bone, which is solid and does not contain marrow.



Where is the femoral anatomy?

The femur is found in the thigh. It is the largest bone in the body and is the only bone in the upper leg. The femur is known as a long bone.

What is the femur made of?

The femur is categorised as a long bone and comprises a diaphysis (shaft or body) and two epiphyses (extremities) that articulate with adjacent bones in the hip and knee.

What is the femur bone connected to?

The femur or thigh bone is one of the longest bones in the human body. The upper part of the thigh bone consists of the femoral head, femoral neck, and greater and lesser trochanters. The head of the femur joins the pelvis (acetabulum) to form the hip joint.

What muscle attaches to the femur?

The quadriceps include four large muscles, rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The quadriceps femoris is one of the strongest muscle groups in the body that covers the anterior aspect of the femur.

What is the femur bone?

The femur bone is the strongest and longest bone in the body, occupying the space of the lower limb, between the hip and knee joints.Femur anatomy is so unique that it makes the bone suitable for supporting the numerous muscular and ligamentous attachments within this region, in addition to maximally extending the limb during ambulation.

What are the two extremities of the femur?

The femur, like other long bones, is divisible into a body and two extremities. The Upper Extremity (proximal extremity, Fig. 243). —The upper extremity presents for examination a head, a neck, a greater and a lesser trochanter.

What cavities are in the femur?

Inside the body of the femur is the medullary cavity, which contains bone marrow. At the ends of the femur are areas of compact bone, which is solid and does not contain marrow. Surrounding the compact bone is spongy bone, which has lots of small cavities dispersed throughout it. The neck and head of the femur contain spongy bone.

Is the medullary cavity inside the femur?

Inside the body of the femur is the medullary cavity, which contains bone marrow. At the ends of the femur are areas of compact bone, which is solid and does not contain marrow. Surrounding the compact bone is spongy bone, which has lots of small cavities dispersed throughout it.
