  • Front
  • Back
articulation
the sites where two or more bones meet
amphiarthosis
slightly moveable joints
suture
seams that occur only between the bones of the skull
syntosis
fibrous tissue that ossifies with age
synchondrosis
bar or plate of cartilage
synovial joints
joints where bones are seperated by a fluid filled joint cavity
synarthroses
immovable joints
diarthroses
freely movable joints
syndesmoses
bones are connected by a liament, a cord or a band of fibrous tissue
gomphoses
peg in socket fibrous joint. the only example is the articulation of a tooth with its socket
symphysis
articular surface of the bones are covered with articular (hyaline) cartilage
bursa
bags of lubrican that act to reduce friction between joint structures during joint activity
insertion
attached to movable bone
origin
attached to least movable bone
extension
reverse of flexion, increases the angle between the articulating bones.
adduction
"moving toward" opposite of abduction. Toward the midline
"digits toward hand or foot"
flexion
decreases the angle of the joint and brings the articulating bones closer together. "head down on chest"
abduction
"moving away" away from midline "raising the arm laterally"
rotation
turning of a bone one its long axis " common at the hip and shoulder joints"
supination
"turning backward" refer to the movement of the radius aroud the ulna "hand anterior or superior"
pronation
"turning forward" refer to the movement of the radius aroud the ulna "hand posterior or inferior"
circumduction
using flexion,extension, abduction and adduction in a wide arch.
inversion
sole of the foot turns medially
eversion
sole of the foot turns laterally
protraction
protracted when you stick out your jaw
retraction
when you move your jaw back to original position
elevation

depression
moving a body part superiorly

moving a body part inferiorly
luxation

subluxation
dislocation, toatally apart

loss of use of the joint
opposition
opposition of the thumb, makes the human hand a fine tool for manipulating objects
tendon
rope like tendon that anchors the muscle to the connective tissue
aponeurosis
sheet like tendon that anchors the muscle to the CT
sarcolemma
plasma membrane of the muscle cell
sarcoplasm
similar to the cytoplasm of other cells but contains an unusually large amount of glycosomes and myoglobin
sarcoplasmic reticulum
elaborate smooth endoplasmic reticulum
myoglobin
red pigment that stores O2 and is similar to hemoglobin
neuromuscular junction
each muscle fiber has only one neuromuscular junction
synapse
gap between the axon terminal and the muscle fiber
