The hip joint: structure, ligaments, muscles, nerves, anatomy, blood supply, movement in the femoral joint. What bones are involved in the formation of the hip joint?

From this article you will learn the anatomy of the hip joint.

The hip joint is a body consisting of cartilage fabric in the form of a ball or cup. It is formed by the head of the femoral bone and the hollow of the pelvis.

• The head of the joint consists of cartilage fabric, and the swivel is covered with such a fabric only on top, its remaining surface consists of synovial membrane tissue.
• The swivel has a sovereign lip, due to which this hole is deeper.
• You will find a detailed anatomy of this cartilage body below.

Hip joint: structure

Building, anatomy: The articular capsule cup of the femur is considered one of the most dense due to the weaving, consisting of a special ligamentous hardware structure. This microcapsular shell is attached to the pelvic bone from the edge of the swivel lip and on the bone of the thigh along the interverter strip. At the back, such a microcapsular shell is in contact with 2/3 of the entire surface of the femur, but it does not apply to an intervering crest.

Links of the femoral joint

Blues: The dense ligament is iliacly naked. It can withstand weight up to 300 kilograms. This node is attached to the anterior iliac spine. It continues to the interverter strip, expanding around the edges. There are still such nodes in this area:

• Pubic. Its beginning on the lane bone strip, the sequel goes down to the interverter strip, and the end in the form of weaving in the articular microcapsular shell. This node is weaker than the previous one, but it serves as a limiter for the movements of the femoral part of the leg.
• Sedidic-packed. The beginning is on the sciatic bone. Continuation in the area of \u200b\u200bthe vertical pit, with weaving into the microcapsular membrane of the node. The main function of this nodal plexus is the limitation of the pronation of the femoral part of the leg.
• Circular knot. It is located inside the microcapsular membrane of the node. Outwardly similar to a circle. It is attached to the iliac spine, covering the transitional bone at the thigh.
• The hip unit. Its main task is to protect the blood supply to the inside. It is located on the inside of the node. It begins on the transverse node and attaches to the hole of the spherical femoral bone.

Muscles near the femoral joint

Muscles: This joint has many different groups of muscles. All of them are responsible for the motor function, flexion and extension of the body in this area. The hip joint consists of several axes of rotation:

• Transverse
• Anteroposterior
• Vertical

The movement of the hip joint

Motor function: In rotation, in each of the axes, the joint involves its muscular group. For example, the transverse axis is responsible for the extension and flexion of the node. Thanks to this muscle, a person can sit down. Here are the muscles participating in the process of bending, extension and abduction:

Blood supply to the tissues of the node

Blood supply of tissue nodules: Provides the medial and lateral arteries. They are located around the femoral part of the leg. Such enlarged vessels make it possible to supply nodes with a blood flow and lymphatic fluid. There are also cutting and gluteal arteries.

For blood outflow, a iliac and deep venous pipe of the femoral part is used. The blood supply to this area of \u200b\u200bthe body depends on physical training. Thanks to sports and constant movement, the joint is established, which helps to prevent the appearance of various diseases.

The nerves of the femoral joint

Nerves of the hip joint Located along the femur.

• The locking nerve is located in the antero-alarm region of the thigh.
• The lower-berry nerve is in the buttock.
• There is also an external skin nerve in this area.

Each of these nerve endings can be pinched with muscles or thigh joints. Therefore, it is important to constantly live in motion so that the joint, muscles, blood supply and other systems function normally.

What bones are involved in the formation of the hip joint?

The anatomy of the bones of the femoral node is this:

• Pubic bone - It consists of a branch of bones located above the other at a slight angle. The vertical pubic symphysis, which fastens the two branches, is also called the Long joint. The body of the pubic bone is determined by the front department of the swivel. The connection in the form of a branch creates a locking valve-this is a hole-membrane.
• Ischium. The lower part of the pelvis. It is connected to the pubic bone. In appearance, it resembles a branch and body. The branch resembles a S-shaped line, which is directed to the pubic bone.
• Ilium - It is located on top of the pelvis. Connects pubic and sciatic bones. As a result of such a joint, ridges are obtained, the surfaces of other small bones. It forms a swivel.
• The thigh bone. Large, resembles the phone. It connects the femoral part, lower leg and pelvis, forming a hip large node. Such a connection is possible using complex ligaments that were described above.

The hip joint is a complex part of the body, consisting of bones, cartilage, many ligaments and other elements. To study the anatomy of this joint thoroughly, you will need a little time, but thanks to this you will know the structure of the femoral bones.
