What are the 3 main joint classifications? -
\Fiborous, Cartiligeneous, Synovial
What is a fiborous joint? -
\bones joined by fiborous tissue, with no joint cavity present. Allow for very little
movement.
Ex: Cranial sutures, teeth and their sockets, tibiofibular joint
What is a cartiligeneous joint? -
\a type of joint where the bones are entirely joined by cartilage These joints generally
allow more movement than fibrous joints but less movement than synovial joints.
Ex: The pubic symphysis. Intervertebral discs
What is a synovial joint? -
\Prevents friction between the articulating bones of the joint cavity.
Types of synovial joints -
\plane, hinge, pivot, condyloid, saddle, ball and socket
Plane joint -
\short slipping or gliding movements; i.e. carpals
pivot joint -
\rotating bone turns around an axis. Allow for limited rotating movements.
i.e. elbow. neck joints.
Condloid Joint/ ellipsoid joint -
\Allow all types of movement except pivotal movements. (knee, wrist).
sadle joint -
\thumb bone
ball and socket joint -
\allow backward, forward, sideways, and rotating movements (shoulders and hips).
hinge joint -
