Memmler's Chapter 6 UPDATED ACTUAL
Questions and CORRECT Answers
function of bones - CORRECT ANSWER - form a sturdy framework. protect delicate
structures, such as the brain and the spinal cord. work as levers with attached muscles to produce
movement. store calcium salts. produce blood cells.
flat bones - CORRECT ANSWER - ribs, cranium
short bones - CORRECT ANSWER - carpals of the wrist, tarsals of the ankle
irregular bones - CORRECT ANSWER - vertebre, facial bones
long bones - CORRECT ANSWER - makes up most of the appendicular skeleton
diaphysis - CORRECT ANSWER - long, narrow shaft of the long bone
medullary cavity - CORRECT ANSWER - center of the diaphysis of a long bones,
contains bone marrow
epiphysis - CORRECT ANSWER - long bone also has two irregular ends, a proximal and
a distal
osseous tissue - CORRECT ANSWER - bone tissue. is the hardest form of connective
tissue
matrix - CORRECT ANSWER - bones hardness and strength reflect the components of
this. It is the material between the living bone cells. Rich in the protein collagen and in calcium
salts.
, minerals - CORRECT ANSWER - calcium salt. with out this substance, bones would bend
easily.
collagen - CORRECT ANSWER - without this, bones would shatter like sticks of chalk.
osteoblast - CORRECT ANSWER - build bone tissue
osteocytes - CORRECT ANSWER - are mature osteoblasts that become trapped in the
bone matrix. they MAINTAIN bones tissue
osteoclasts - CORRECT ANSWER - large, multinucleate cells responsible for the process
of resorption, the break downs of bone tissue
compact bones - CORRECT ANSWER - hard and dense osseous tissue. makes up with
main shaft of a long bone and the outer layer of other bones.
perforating canals - CORRECT ANSWER - form channels across the bone, from one side
of the shaft to the other, permitting the passage of blood vessels
spongy bones - CORRECT ANSWER - cancellous bone. has more spaces than does the
compact bones, is made of a meshwork of small, bones plates filled with red marrow. found at
the epiphyses (ends) of the long bones and at the center of other bones.
red marrow - CORRECT ANSWER - found in the spongy bone at the ends of the long
bones and at the center of other bones. Manufactures blood cells.
Yellow marrow - CORRECT ANSWER - found chiefly in the central cavities of the long
bones. composed largely of fat.
periosteum - CORRECT ANSWER - membrane covering bones (except at the joint
region)
