An example of a slightly movable joint or amphiarthrosis is

synchondrosis or the cartilage between the ribs and the sternum and the pubic symphysis

In a synovial joint, _________ tie muscles to bones

tendons

An example of a cartilaginous joint is...

the pubic symphysis or the discs between verebrae

Fibrous joints...

do not have a joint capsule and are composed of fibrous connective tissue

Skull bones are joined by tight connections representing a fibrous joint are called

sutures

An example of an immovable joint or synarthroses is

sutures in the skull

Joints can also be classified by movement. The 3 categories of joints cased on movement are

synarthrosis (immovable), amphiarthrosis (slightly movable), and diarthrosis (freely movable)

Cartilaginous joints are

Fibrous cartilage discs that act as shock absorbers in joints are called ______

menisci

________ is a movement that occurs in the anterior-posterior plane and increases the angle between the articulating bones. An example would be straightening your elbow.

An example of a freely movable joint or diarthroses is

a synovial joint

A movement away from the longitudinal axis of the body in the frontal plane

abduction

A movement toward the longitudinal axis of the body in the frontal plane (toward the middle of the body) is termed

adduction

Typical movements at a hinge joint include
