Joints and movements
Which joint type can perform rotation movements?
ball and socket
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
composed of cartilage and are slightly movable
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.
Extension
The 3 categories of joints based on structure are
Fibrous, cartilaginous, and synovial
Movement in the anterior-posterior plane that decreases the angle between articulating bones is which movement?
Flexion
The knee is an example of a (n)
freely movable, synovial joint
The special movement of the thumb that allows it to grasp an object and hold onto it is called
opposition
Moving the arm in a loop is an example of which angular movement?
Circumduction
Which of the following is a function of synovial fluid?

A synovial joint structurally has
a joint cavity and movement
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
extension and flexion
Movements of the vertebral column are limited to
flexion and extension, lateral flexion, and rotation
Found outside or inside a joint capsule, structures that join bone to bone are called
