What is the general anatomy of the hip?
General Hip Anatomy. The hip is a ball-and-socket joint, similar to the joint in the shoulder. Part of the reason for the hip’s stability is that there is a very deep socket, called the acetabulum, in the hip joint. A strong capsule joint supported by ligaments and muscles also provides extra stability to the hip.
What provides stability to the hip joint?
A strong capsule joint supported by ligaments and muscles also provides extra stability to the hip. The hip has different layers to it, with the deepest layer being the bones that comprise it. On top of these bones are the ligaments that surround the joint capsule.
What is the function of the hip bone?
The hip helps the body maintain balance and assists in ambulation. The bones of the hip include the femur, the ilium, the ischium, and the pubis. The pubis, ischium, and ilium together constitute the pelvis while the thigh bone is the femur.
Why is the hip important?
The hip is a joint that is responsible for supporting the body’s weight during both movement and rest periods. The hip helps the body maintain balance and assists in ambulation. “As you get older, you can suffer from painful hips, and our joints wear a lot quicker than for people of average height.”. — Warwick Davis.
Why is the hip so stable?
Part of the reason for the hip’s stability is that there is a very deep socket, called the acetabulum, in the hip joint. A strong capsule joint supported by ligaments and muscles also provides extra stability to the hip. The hip has different layers to it, with the deepest layer being the bones that comprise it.
What are the ligaments that surround the hip?
There are a variety of ligaments which encircle the hip and give it support. These ligaments found within the hip include the pubofemoral ligaments, the ischiofemoral ligaments, and the iliofemoral ligaments. These three ligaments together make up the extracapsular ligaments. These ligaments form the joint capsule and encircle the entire hip joint. The strongest out of the three ligaments is the iliofemoral ligament. A condition known as avascular necrosis results from the damaging of the ligamentum teres. The condition results when the small artery that supplies blood to the femur is damaged.
What are the muscles and tendons in the hip joint made of?
Finally, on the top layer are the blood vessels and nerves. The hip joint is made out of fibrous, dense tissue – and these tissue groups include the ischiofemoral, pubofemoral, iliofemoral ligaments.
Which bone is the longest?
The longest bone in the body is the femur. The femoral head is connected to the shaft by the femur ’s neck. The hip joint is attached to the posterior surface of the femoral neck via the capsular ligament. The neck of the femur terminates at the lesser and greater trochanter prominences.
What are the structures that make up the hip?
Those are the joints and bones which make up the hip, but to understand the role these joints/bones play in the body, a closer look at these structures is necessary.
How do the muscles of the hip work together?
The muscles work together to enable movement and keep the hip in alignment. The hip muscles work together to carry out 4 different types of movement: extension, flexion, adduction, and abduction. The muscles of the hip can be divided into three different groups.

Where is the articulation of the C1?
These are found at the articulation between the C1 (atlas) and the dens of the C2 (axis) vertebrae, which provides the side-to-side rotation of the head, or at the proximal radioulnar joint between the head of the radius and the radial notch of the ulna, which allows for rotation of the radius during forearm movements.
What are the structural classifications of joints?
Structural classifications of the body joints are based on how the bones are held together and articulate with each other. At fibrous joints, the adjacent bones are directly united to each other by fibrous connective tissue. Similarly, at a cartilaginous joint, the adjacent bones are united by cartilage. In contrast, at a synovial joint, the ...
What is the classification of a joint?
The functional classification of body joints is based on the degree of movement found at each joint. A synarthrosis is a joint that is essentially immobile. This type of joint provides for a strong connection between the adjacent bones, which serves to protect internal structures such as the brain or heart. Examples include the fibrous joints of the skull sutures and the cartilaginous manubriosternal joint. A joint that allows for limited movement is an amphiarthrosis. An example is the pubic symphysis of the pelvis, the cartilaginous joint that strongly unites the right and left hip bones of the pelvis. The cartilaginous joints in which vertebrae are united by intervertebral discs provide for small movements between the adjacent vertebrae and are also an amphiarthrosis type of joint. Thus, based on their movement ability, both fibrous and cartilaginous joints are functionally classified as a synarthrosis or amphiarthrosis.
Which joint allows for flexion and extension?
Each of the different structural types of synovial joints also allow for specific motions. The atlantoaxial pivot joint provides side-to-side rotation of the head, while the proximal radioulnar articulation allows for rotation of the radius during pronation and supination of the forearm. Hinge joints, such as at the knee and elbow, allow only for flexion and extension. Similarly, the hinge joint of the ankle only allows for dorsiflexion and plantar flexion of the foot.
Which joints allow for bending and straightening of the joints?
Hinge joints, such as at the elbow, knee, ankle, or interphalangeal joints between phalanx bones of the fingers and toes, allow only for bending and straightening of the joint. Pivot and hinge joints are functionally classified as uniaxial joints.
How do synovial joints work?
Synovial joints are strengthened by the presence of ligaments, which hold the bones together and resist excessive or abnormal movements of the joint. Ligaments are classified as extrinsic ligaments if they are located outside of the articular capsule, intrinsic ligaments if they are fused to the wall of the articular capsule, or intracapsular ligaments if they are located inside the articular capsule. Some synovial joints also have an articular disc (meniscus), which can provide padding between the bones, smooth their movements, or strongly join the bones together to strengthen the joint. Muscles and their tendons acting across a joint can also increase their contractile strength when needed, thus providing indirect support for the joint.
