Joints room the areas where 2 or an ext bones meet. Most joints space mobile, allowing the bones come move. Joints covers the following:

Cartilage. This is a form of organization that covers the surface ar of a bone at a joint. Cartilage helps minimize the friction of activity within a joint.

Synovial membrane. A tissue called the synovial membrane lines the joint and also seals it right into a share capsule. The synovial membrane secretes a clear, sticky fluid(synovial fluid) approximately the joint to lubricate it.

Ligaments. Strong ligaments (tough, elastic bands the connective tissue) surround the share to give support and limit the joint"s movement. Ligaments connect bones together.

Tendons. Tendons (another form of hard connective tissue) on each side the a joint attach to muscle that manage movement that the joint. Tendons affix muscles come bones.

Bursas. Fluid-filled sacs, dubbed bursas, in between bones, ligaments, or other nearbystructures. They aid cushion the friction in a joint.

Synovial fluid. A clear, sticky liquid secreted by the synovial membrane.

Meniscus. This is a curved part of cartilage in the knees and also other joints.

What room the different types of joints?

There are many species of joints, including joints the don’tmove in adults, such as the suture joints in the skull. Joints that don’tmove are called fixed. Other joints might move a little, such as the vertebrae. Examples of mobile joints incorporate the following:

Ball-and-socket joints. Ball-and-socket joints, such together the shoulder and also hip joints, allow backward, forward, sideways, and also rotating movements.

Hinge joints. Hinge joints, such as in the fingers, knees, elbows, and also toes, enable only bending and straightening movements.

Pivot joints. Pivot joints, such as the neck joints, allow limited rotating movements.

Ellipsoidal joints. Ellipsoidal joints, such together the wrist joint, permit all species of movement other than pivotal movements.
