APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Ligaments connect bones together. Tendons. Tendons (another type of tough connective tissue) on each side of a joint attach to muscles that control movement of the joint. Tendons connect muscles to bones.

Detailed explanation-2: -Flexion/Extension The movement at a joint which decreases the angle between two adjacent body segments is know as flexion. The opposite action is extension, where the angle between body segments is increased.

Detailed explanation-3: -Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. In extension, the opposite of flexion, the angle between the bones of a joint increases.

Detailed explanation-4: -Joints are movable connections between two bones. Each joint is made up of the surfaces of the bones involved, a joint cavity and a joint capsule. The joint surfaces (articular surfaces) of the bones are covered with a layer of cartilage. This layer is between 0.2 and 0.5 mm thick, and up to 6 mm thick on the kneecap.
