The knee is a mobile trocho-ginglymus (i.e. a pivotal hinge joint), which permits flexion and extension as well as a slight medial and lateral rotation. It has more movement that a basic hinge (like a door) this is needed to walk properly
The knee is not a pure hinge joint. The knee is classified as a trocho-ginglymus (a pivotal hinge joint). The knee has primary motions in the sagittal plane into flexion and extension, but will allow some frontal plane motion into abduction/adduction as well as some internal and external rotation in the transverse plane. In addition the femur rotates and slides on the tibial plateau.
Hinge joints allow movement in one direction, as seen in the knees and elbows and fingers.
FUNCTION: The purpose of joints is to provide movement for the body. Different types of joints move in different ways. The hinge joint is shaped to restrict movement to one plane. It has strong collateral ligaments that aid and restrict movement. The ends of the bones are covered with tough cartilage and are lined with the synovial membrane.
Each joint contains a small amount of synovial fluid which lubricates it. Synovial fluid provides protection for the hinge joint and allows for its stress-free movement.
The hinge joint provides a connection that allows articular surfaces to be closely molded together. This molding together permits extensive motion in one plane. The joint has stabilizing ligaments that limit the directions and extent to which the bones can be moved. The hinge joint moves back and forth with some rotation allowed.
-->*Pivot joints allow a rotating or twisting motion, like that of the head moving from side to side.The rotation of the skull is made possible by a pivot joint.
FUNCTION: A pivot joint allows movement in one plane, such as rotation about an axis. Pivot joints, for example, permit one, after bending the elbow, to turn the palm of one's hand upward or downward by rotating the forearm. The two bones of the forearm (the ulna and the radius) twist around each other using a pivot joint.
STRUCTURE: Pivot joints hold the two bones of the forearm together. That is, a pivot joint, located near the elbow, joins the bones of the forearm (called the ulna and the radius) to each other. These two bones are also joined to each other near the wrist by another pivot joint. A different pivot joint, located at the base of the skull, joins the first vertebra of the spine to the second vertebra and thus permits the head to rotate (since the first vertebra is joined to the skull).
If the bony surfaces of two bones that meet at a joint actually touched each other, then motion would cause friction, which would soon produce wear and tear on the touching ends of the bones. An engineer designing a mechanical counterpart would arrange for lubricating oil to prevent such wear and tear and facilitate smooth movement between the two metal "bones." A joint thus holds bones together (it is called a "joint" because it "joins" them) but also keeps them slightly separated to prevent their damaging each other in motion.
it only opens one way
The four movable joints are- 1. Ball and Socket joint(between humerus and pectoral girdle) 2. Hinge joint(Knee joint) 3. Pivot joint(between atlas and axis) 4. Gliding joint(between carpals).The four kinds of movable joints are hinge joint, ball-and-socket joint, pivot joint ,and gliding joint.~ A. K. =)four types of movable joints are hinge joint , ball-and-socket joint , pivot joint , and gliding joint.Ball-and-socket, Hinge, Pivot, and Gliding joints.The four types of the movable joints are the ball and socket joint, hinge joint, pivot joint, and gliding joint.
No, knee joint is a compound joint (condyloid joint between tibia and femur and saddle joint between femur and patella).Yes, there is a pivot joint in the knee. Pivot joints can also be found in a person's neck, forearms, and other parts of the body. This is because the pivot joint moves by rotating.The knee is mainly a hinge joint not a pivot joint.
The knees, toes, and fingers are all hinge synovial joints.
Elbow joint consists of three joints:Joint between trochlea of Humerus and Ulna is hinge joint (ginglymus joint).Joint between capitulum of humerus and head of radius is also a hinge joint.Joint between Upper ends of radius and ulna is pivot joint.
Part of the elbow is a ball and socket joint, but the elbow is made up of three different kinds of joint.The first joint is between the Humerus (bone of the upper arm) and the Ulna (the larger of the two forearm bones) which is a Hinge Joint. Hinge joints allow for movement along one plane. In the arm, this allows the movement used when a person touches their shoulder with the hand of the same arm.The second joint is between the Humerus and the Radius (the smaller of the two forearm bones) and this is a ball and socket joint.The third joint is between the Radius and the Ulna and this is a pivot joint. A pivot joint allows rotation of a joint, in the arm this allows the movement used when turning the palms upwards or downwards.

A hinge point opens or closes in one angle direction only. A pivot joint could angle in several different directions.A hinge in your home can be found at the door. When a person opens or closes the door, that is the motion of a hinge. A hinge joint in the body is the same way. You find a hinge joint in the elbow, the knee, and the lower jaw.A pivot joint is found between the first two vertebrae in the neck and allows you to shake your head "no" or look to the left or right. Another pivot joint is found in the wrist. When you turn your hand up to to accept a coin, you are using a pivot joint.
