what are joints referred to
articulations
what are articulations
where two bones meet
how are joints classified structurally
fibrous or cartilaginous
joints can be classified functionally as
synarthroses, amphiarthroses, diarthroses
what are synarthroses joints
immovable (skull)
what are amphiarthroses joints
slightly moveable (pubic sympthasis)
what are diarthroses joints
freely moveable
what are fibrous joints
no movement
no joint cavity
fibrous joints
fibrous tissue present between the bones
fibrous joints
synarthroses is considered a __________ joint
fibrous
what are the three type of fibrous joints
sutures, syndesmoses, gomphoses
where can you find sutures
between the skull bones
where can you find syndesmoses
connected by ligaments
interrosseous membrane connecting the radius and ulna
where can you find gomphoses
tooth attached to the socket in the alveolar process of the maxilla and mandible by the periodontal ligament
do cartilaginous joints have joint cavity
no
cartilaginous joints have cartilage present where
between two bones
what kind of joints is an amphiarthroses joint
cartilaginous
types of cartilaginous joints
synchondroses, symphyses, and synovial
examples of synchondroses joints
first rib and sternum
growth plate (epiphyseal cartilage)
hyaline cartilage between two bones
which joints are slightly moveable
amphiarthroses and symphses
example of symphyses
public symphses, and fibrocartilage
when joint cavity is present it is called a
synovial joint
which joints have no tissue attaching the two bones
synovial
which joints are moveable
synovial
joint types are based on what
the shape of the opposing bone surfaces
plane or gliding joint definition
opposing surfaces are flat and equal
what is the movement of plant or gliding joints
nonaxial
examples of plane or gliding joints
intercarpal joints, intertarsal, joints between vertebra articular surface
define hinge joint
one opposing surface is concave while the other one is convex
movement of hinge joint
monoaxial or uniaxial
examples of hinge joint
elbow, knee and interphalangeal joints
pivot joint define
one opposing surface forms a ring through which the other opposing surface goes through
pivot joint movement
monoaxial
example of pivot joint
atalantoxial joint (joint between c1 and c2)
condylar joint define
one opposing surface forms a cup, the other surface fits in it
movement of condylar joint
biaxial
examples of condylar joint
metacarpal phalangeal joint
define saddle joint
one opposing surface forms both concave and convex and the other one does too
movement of saddle joint
biaxial
examples of saddle joint
carpometarpal joint of the thumb
define ball and socket joint
one opposing surface forms a socket and the other forms a ball
movement of ball and socket joint
multiaxial
examples of ball and socket joint
shoulder joint and hip joint
the bones are connected exclusively by ligaments
syndesmoses
