l l

Types of Joints Joint : where two or more bones meet Joints and Movement: Different joints have varying degrees of movement Three types of joints fibrous joints cartilaginous joints synovial joints

Fibrous Joints Fibrous joints: Bones that are connected together without gaps. Fibrous joints, movement: Not mobile

Cartilaginous Joint Cartilaginous joints: Bones connected by a small cushion of cartilage. This cartilage acts as a shock absorber, protecting the joint from impact. Cartilaginous joints and Movement: Restricted movement

Synovial Joints Synovial joints: Joints where the surface of the bone is covered with a layer of slippery cartilage. Found in the arms and legs Synovial joints and movement: Joints that move freely Synovial Membrane: Found in the joining surface. Secretes a slippery fluids onto the surface of the joint

Types of Movement Hinge A hinge joint allows extension and retraction of an appendage. Found in: Elbow and knees

Ligaments and Tendons Ligaments: Connective tissue that joins bones to other bones.

Found in: Ankles, wrists, knees, and hands

Ligaments and Tendons Ligaments: Connective tissue that joins bones to other bones.

Found in: Ankles, wrists, knees, and hands Tendons: Connective tissue that joins bone to muscle. Found in: Where ever muscle and bone connect .

Tendons Brusae: Fluid filled sacs between bone and tendon. Function of the brusae: Reduce the rubbing of the tendon on bone
