What are the 3 articulations of the knee?

The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or “kneecap”, and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations …

Do knees hinge or twist?

The knee is a hinge joint but it also has the ability to rotate slightly as it moves. The contraction of muscles at the front of the thigh (quadriceps) straightens the leg, while contraction of the muscles at the back of the thigh (hamstrings) allow the leg to bend at the knee.

Is the knee a hinge or Condyloid joint?

The knee and ankle joints are hinge joints that also allow some rotary movement. See illustration. Called also ginglymus. hip joint the synovial joint formed at the head of the femur and the acetabulum of the hip.

Why is the knee classified as a modified hinge joint quizlet?

Why is the knee classified as a modified hinge joint? Because of the action of the rotation of the fibula. The popliteus is responsible for what action in the knee? Which of the following movements is the peroneus longus capable of performing?

What structure contributes to the knee joint?

The knee joint is formed by the thighbone, or femur, and the tibia, the larger of the two lower leg bones. The fibula, the smaller of the lower leg bones, fits into a depression of the tibia. The knee joint permits both a hinge-like motion between the upper and lower leg and a slight side-to-side motion.

What are intra-articular structures of knee joint?

Menisci and cruciate ligaments are intra-articular structures of knee, and injury to these structures is common.

Is the knee a hinge joint?

Is patella intra-articular?

Intra-articular dislocations of the patella are rare and are of two types, horizontal and vertical. The most common type is a horizontal intra-articular dislocation of the patella. Horizontal dislocation has two types. In one type, the articular surface of the patella is directed toward the tibial articular surface.

What are articular structures?

27669. Fig. 4.42 B Intra-articular structures and their importance to functional integrity of joints: menisci, articular disks, and articular labra – a Crescent-shaped structures, wedge-shaped in cross section, formed regularly in the knee only, which consist of collagen fibers, connective tissue, and fibrous cartilage …

Is knee joint a pivot joint?

The knee joint is a hinge joint. Like a door hinge, a hinge joint allows backward and forward movement. The pivot joint (Figure below) only allows rotating movement. An example of a pivot joint is the joint between the radius and ulna that allows you to turn the palm of your hand up and down.

Which joints are ball and socket?

The hip joint is known as a ball-and-socket joint. The rounded head of the femur articulates with the acetabulum, which is formed by the junction of the ilium, ischium, and pubis. The nature of the joint and its innervations may result in primary pain conditions of the hip.

Is the knee a pure hinge joint?

The knee functions as a modified hinge joint, allowing flexion and extension of the leg. This action is generated by both rolling and gliding motions of the femur on the tibia. In addition, some rotation of the leg is available when the knee is flexed, but not when fully extended.
