Chap. 9: Joints
sutures
Synarthrotic fibrous joints between the bones of the skull are called
synovial
a joint in which bones are separated by a narrow, fluid-filled encapsulated space is a __________ joint.
symphysis
a joint in which fibrocartilage binds together is a
biaxial
a joint that can move in two planes is
flexion
a movement that decreases a joint angle
extension
a movement that straightens a joint, returning t to zero position is
joint
a point where two bones meet
joint inflammation
arthritis is a disorder that involves
meniscus
crescent- shaped piece of fibrocartilage that functions to absorb shock and stabilize the joint
stabilize joint, absorb shock, and guide bones across each other
functions of the menisci of the knee
synovial membrane
inner layer of joint capsule
hip and shoulder
examples of ball-and-socket joints
synarthroses
fibrous joints are also called
bursa
fibrous sac filled synovial fluid
synostinosis
a suture is an example of bony, immovable joints called
based on the names of bones involved in the joint
how are individual joints typically named?
rheumatism
the broad term that describes any pain in the body including bones, ligaments, tendons, and muscles is
synovial membrane and fibrous capsule
the components of a joint capsule
stabilize joint and attach muscle to bone
the functions of a tendon
diarthroidial
the most familiar type of joint hat is generally freely moveable are _______ joints.
gomphosis
the socket for your tooth
syndesmosis joint
the type of fibrous joint in which the bones are held together by only a ligament or band of fibrous tissue and the length of fibers give these joint more mobility is called
osteoarthritis
they type of arthritis you would expect from years of wear on the joints is
articular cartilage
layer of hyaline cartilage on the surface of the articulating bones
depression
lowering mandible and opening mouth
hinge
monaxial joint with a convex surface that fits into a concave depression
pivot
monoaxial joint in which a bone spins on its longitudinalaxis
tendon
a strip or sheet of tough collagenous tissue attaching muscle to bone is called a
protraction
moving mandible forward so incisors meet
ball and socket
multiaxial joint with a hemispherical head that fits into a cuplike depression
ligament
a strip of collagenous tissue attaching bone to bone
fibrous capsule
outer layer of joint capsule continuous with the periosteum
symphyses, synchondroses
types of cartilaginous joints
plane
usualla a biaxial joint between flat surfaces or surfaces that are only slightly concave and convex
