skeletal system Flashcards
tissue found at the end of long bones (epiphysis)
spongy
responsible for reabsorption or the breakdown of the bone
osteoclasts
bones stop growing in length around the age of
late teens or early 20’s
list functions of bones
framework for body, protects organs, serves as levels to produce movement, stores calcium salts, and produces blood cells (hemopoiesis)
a hole that allows a vessel or nerve to pass through is a
foreman
an air space found in some skull is a
sinus
the short channel or passageway that leads into the portions of the inner ear
meatus
the last 4-5 fused vertebrae in an adult spine

radius
the ischium is found on the

7
a congenital deformity in the roof of the mouth
cleft plate
paget’s disease is also known as
osteitis deformans
an excessive lumbar curve (swayback)
lordosis
what are the results of the aging process
loss of calcium salts, decreased production of collagen, thinning of intervertebral disks
a fracture where one side of the bone is bent and the other side is broken
greenstick
type of fracture where bond is twisted apart
spiral
a joint that is classified as synarthrosis (fibrous)
a suture between bones of the skull
fluid filled sacs near joints
bursae
allows for movement in many directions
ball and socket
allows movement in one direction
hinge
the shoulder joint is a
ball and socket joint
movement away from the midlineof the body
abduction
twisting of a bone on its own axis
rotation
turning the palm backwards
pronation
pointing the toes downward
plantar flexion
bending motion that decreases the angle between bones
flexion
derangement of the parts of the joint
dislocation
wrenching of a joint
sprain
