Femur (Thigh Bone)

Femur (Thigh Bone): anatomy and functions

The femur bone, also known as the femur, is the longest and largest bone in the human body. This long bone plays a key role in maintaining the stability of the hip and knee joints, and also allows the movement of the leg.

Anatomy of the Femur

The head of the femur articulates with the acetabulum of the pelvic bone to form the hip joint. This hinge joint allows for a variety of movements, including leg lifting, rotation, and flexion. The greater trochanter and lesser trochanter are the protrusions on the femur to which the thigh muscles attach. The gluteus medius, minimus, and psoas major muscles attach to the greater trochanter, while the lesser trochanter serves as the attachment point for the muscles that control hip movement.

On the lower epiphysis of the femur there are two condyles: lateral (lateral condyle) and medial (medial condyle), which are connected to the tibia, forming the knee joint. This design allows the leg to bend and extend at the knee joint. The patellar surface on the anterior surface of the lower epiphysis is adapted to the shape of the patella and articulates with it.

The femoral neck, which connects the head of the femur to its shaft, is the most common site of hip fracture in older women. This is because as women age, bone density decreases, making the femur more susceptible to fracture.

Functions of the femur bone

The femur bone performs several important functions in the human body. First of all, it serves to maintain the stability of the hip and knee joints, allowing a person to move and perform various physical activities. In addition, this bone plays an important role in absorbing shock during walking and running, reducing the risk of injury and damage.

Partial displacement of the femoral epiphysis in the growth zone (metaepiphysis) at the upper end of the bone can lead to deformation of the femoral head and premature degenerative changes in the hip joint. Therefore, it is important to monitor the condition of your bones and your overall health in order to prevent possible problems with bone tissue.

In addition, the femur bone is an important source of hematopoietic tissue, producing red blood cells that carry oxygen throughout the body. The femur also contains yellow bone marrow, which is responsible for producing white blood cells necessary to protect the body from infection and disease.

Conclusion

The femur bone plays an important role in the human body, providing support and movement of the body. Its anatomy and functions are related to the hip and knee joints, as well as the hematopoietic system. Therefore, it is important to pay enough attention to the health of bones and joints to maintain their functionality throughout life.

The femur (Femur) is a long tubular bone that is found in the lower part of the body. It plays an important role in leg movement and maintaining balance.

The head of the femur connects to the acetabulum in the pelvic bone and forms the hip joint. The greater and lesser trochanters are projections that attach to the gluteus medius, minimus, and psoas major muscles.

On the lower epiphysis there are two condyles, which connect to the tibia and form the knee joint. The patellar surface on the anterior surface of the epiphysis is adapted to the shape of the patella, which articulates with it.

The femoral neck is the most common fracture site in older women and connects the head of the femur to its shaft. Fractures of the femoral epiphyses also occur, which can be caused by trauma or osteoporosis.

Overall, the femur bone is an important part of the musculoskeletal system and plays a key role in maintaining human health and functionality.

Femur bone is a word that many people do not know and they know little about it. For doctors, this topic is very important, because it belongs to the class of bones. You've probably noticed that the lower part of the thigh is slightly larger than the upper part. In fact, this is the femur bone. If we talk about its structure, then the femoral part has a head and a neck. Many people also know that it is taken at the base of the knee joint.

The tibia and femur also connect to form the knee joint. It has another name - blockade joint. The spiral ligamentous apparatus helps maintain it during active movements. But with age, deformation and degeneration of the hip joints appears. So-called degenerative arthrosis occurs, which threatens the disease if left untreated. Deforming arthrosis is so called because the joints themselves become deformed. At the same time, the bones are slowly destroyed. The hips experience increased stress due to excess weight and salt deposits.
