Synarthroses Joint
a type of joint that is immovable or nearly immovable, and is characterized by a strong union between the bones that make up the joint
Diarthrosis Joint
a freely movable joint, also known as a synovial joint, that allows for a wide range of movement in the body
Fibrous Joint

Cartilaginous Joint
a joint where bones are connected by cartilage, a tough but flexible connective tissue
Gomphosis
a type of joint that attaches the roots of teeth to their sockets in the upper and lower jaw bones
Non-axial Joint Movement
a type of joint movement that does not involve bending along an axis of movement

Capsule (Capsular Ligament)
a thickened area of a joint capsule that surrounds synovial joints
Synovial Membrane
a thin layer of connective tissue that lines the inside of joints, tendon sheaths, and bursae
Synovial Fluid
a thick, viscous liquid that lubricates and protects your joints
Cartilage
A tough, flexible tissue that lines joints and gives structure to the nose, ears, larynx, and other parts of the body
Hyaline Cartilage (Articular)
a type of hyaline cartilage that covers the ends of bones in joints
Fibrocartilage
a type of connective tissue that is tough, strong, and inflexible, and is made up of a combination of cartilage and fibrous tissue
