Another name for articulations
joints
sites where 2 or more bones meet
joints
What are the 2 fundamental functions of joints
skeleton mobility and hold it together (protective role)
how are joints classified
structure and function
what are the structural joints

which joint has a joint cavity
synovial joint
what are the functional joints
synarthroses
amphiarthroses
diarthroses
immovable joints
synarthroses
slightly movable joints
amphiarthroses
freely movable joints
diarthroses
freely moveable joints are predominately where
limbs
immovable and slightly movable joints are where
restricted to axial skeleton
are fibrous joints immovable
yes
are synovial joints freely movable
yes
T or F. Cartilaginous joints have both rigid and slightly movable examples
true
Every skeletal muscle of the body is attached to bone or other connective tissue structures at no fewer than how many points
2
what is attached to the immovable part of the muscle
origin
in the other end, it is attached to the movable bone
insertion
slipping movement away
nonaxial movement
movement in one plane
uniaxial movement
movement in two planes
biaxial movement
movement in or around all three planes
multiaxial movement
what are the three general types of movement
gliding, angular movements, rotation
occurs when one flat or nearly flat bone surface glides or slips over another (back & forth, side to side)
gliding movement
increase or decrease the angle between two bones and includes flexion, extension, hyperextension, abduction, and curcumduction
angular movements
bending movement, usually sagittal plane, that decreases the angle of the joint and brings articulating bones closer
flexion
reverse of flexion and occurs at same joint; movement along sagital plan that increases angle between articulating bones (strainghtens a flexed limb or body part)
extension
movement of a limb away from midline or median plane of body
abduction
opposite of abduction; movement of a limb toward the body, midline, or toward the midline of the hand or foot
adduction
turning of a bone around its own long axis; only movement allowed between the first 2 cervical vertebrae; common at hip
rotation
refer to the movements of the radius around the ulna
supp\ination and pronation
spination is
turning backward
pronation is
turning forward
Lifting the foot so its superior surface approaches the shin; corresponds to wrist extension
dorsiflexion
depressing the foot (pointing the toes); corresponds to wrist flexion
plantar flexion
sole of the foot turns medially
inversion
the sole of the foot faces laterally
eversion
nonangular anterior in a transverse plane
protraction
posterior movements in a transverse plane
retraction
lifting a body part superiorly
elevation
moving the elevated part inferiorly
depression
the saddle joint between metacarpal I and the trapzium allow a movement called what?
opposition
Examples of synovial joints
knee, shoulder, elbow, hip, temporomandibular joint
Plane joint has what kind of movement
nonaixal movement-gliding
hinge joint has what kind of movement
uniaxial movement-flexion and extension
pivot joint has what kind of movement
uniaxial movement-rotation
condylar joint has what kind of movement
biaxial movement-flexion and extension; adduction and abduction
saddle joint has what kind of movement
biaxial movement-flexion and extension; adduction and abduction
ball and socket joint has what kind of movement
multiaxial movement-flexion and extension; adduction and abduction; rotation
