A&P: CH. 8 & 9: MUSCULOSKELETAL
QUESTIONS AND ANSWERS 100%
CORRECT.
epiphysis - ANSWEREnlarged end of a long bone
epiphyseal disc - ANSWERgrowth plate
diaphysis - ANSWERShaft of a long bone
medullary cavity - ANSWERHollow center of a long bone
haversian system - ANSWEROsteon
red bone marrow - ANSWERSite of blood cell production
femur - ANSWERThe head of this bone that articulates with the acetabulum
scapula - ANSWERContains the glenoid cavity that holds the head of the humerus
mandible - ANSWERLower jaw bone
ulna - ANSWERContains the "pointy" olecranon process
Sternum - ANSWERManubrium, body, xiphoid process
Coxal bone - ANSWERAcetabulum formed by parts of this bone
Tibia - ANSWERThe thick inner bone of the leg
Calcaneus - ANSWERHeel bone
Frontal - ANSWERForms the forehead
Phalanges - ANSWERFingers and toes
cartilage - ANSWERConnective tissue
ligaments - ANSWERBone to bone
What does the skeletal system do? - ANSWERSupports the body weight
Protects soft organs
, Enables body movement with muscles
Stores calcium and phosphorus
Contains bone marrow (produces RBC; red blood cell)
long bones - ANSWERfemur, humerus, metacarpals and phalanges
short bones - ANSWERbones of the wrist and ankles
flat bones - ANSWERribs, sternum, and bones of the shoulder girdle
irregular bones - ANSWERhip bones, vertebrae
ossification - ANSWERprocess of bone formation
osteoblasts
"B"uilder - ANSWERbone cells that secrete an intercellular matrix containing calcium,
other minerals and protein fibers. bone BUILDING cells
compact bone - ANSWERdense, compact and hard
located in the shafts of long bones and outer surfaces of other bones
fractures are uncommon (strong, solid)
osteon - ANSWERmakes compact bone hard. mature osteocytes arranged in concentric
circle. also known as; haversian system
spongy bone - ANSWERfound at the end of long bones and center of other bones
cancellous bone
fractures are common because of the spaces
longitudinal growth
"growing bones" - ANSWERoccurs in the epiphyseal disc/growth plate
they are affected by hormones; growth hormones and sex hormones (estrogen and
testosterone)
sex hormones causes the plate to close and the epiphyseal disc is more sensitive to
estrogen
What age does a female stop growing? - ANSWER18 years old
What age does a male stop growing? - ANSWER21 years old
What do steroids induce? - ANSWERPremature fusion of the epiphyseal plate which
permanently stunts growth
osteoclasts
"C"hewing - ANSWERbone destroying cells
