Front (Question)

red marrow function

Back (Answer)

red marrow is the site of blood cell production (hematopoiesis)

Front (Question)

yellow marrow function

Back (Answer)

where fat is stored

Front (Question)

two minerals stored in bone

Back (Answer)

calcium and phosphorus

Front (Question)

Skeletal system = supports the body (HOW)

Back (Answer)

the rigid yet flexible skeleton acts as a framework to support the other organs of the body

Front (Question)

skeletal system = facilitates movement

Back (Answer)

the movable joints allow the skeleton to change shape and positions: that is, move

Front (Question)

skeletal system = protects internal organs

Back (Answer)

parts of the skeleton enclose or partly enclose various organs of the body including out brain, ears, heart, and lungs

Front (Question)

skeletal system = produces blood cells

Back (Answer)

the central cavity of long bones is filled with marrow. red marrow is responsible for forming red and white blood cells

Front (Question)

skeletal system = stores and releases minerals and fat

Back (Answer)

the mineral component of bone, in addition to providing hardness to bone, provides a mineral reservoir that can be tapped as needed. additionally, the yellow marrow, which is found in the central cavity of long bones along with red marrow, serves as a storage site for fat

Front (Question)

flat bones found in the head

Back (Answer)

cranial bone (frontal, parietal, occipital, or temporal)

#10

Front (Question)

flat bone found in the shoulder

Back (Answer)

scapula

#11

Front (Question)

flat bone(s) found in the chest area

Back (Answer)

sternum / rib

#12

Front (Question)

only two examples of short bones found in the human body

Back (Answer)

carpals and tarsals

#13

Front (Question)

sesamoid bone found in the lower extremity

Back (Answer)

patella

#14

Front (Question)

long bone found in the upper extremity

Back (Answer)

humerus, radius, ulna

#15

Front (Question)

long bone found in the lower extremity

Back (Answer)

femur, tibia, fibula

#16

Front (Question)

long bone found in the hand

Back (Answer)

metacarpal or phalanx

#17

Front (Question)

long bone found in the foot

Back (Answer)

metatarsal or phlanx

#18

Front (Question)

irregular bone

Back (Answer)

vertebra

#19

Front (Question)

osteogenic cells

Back (Answer)

the only bone cells that do mitosis and thus are used to create more bone cells

#20

Front (Question)

osteoclasts

Back (Answer)

multinucleated bone cells that break down bown tissue so that it can be rebuilt/remodeled

#21

Front (Question)

osteoblasts

Back (Answer)

line the medullary cavity where they make more bone tissue

#22

Front (Question)

osteocytes

Back (Answer)

they are osteoblasts that have become completely surrounded by bone tissue, they continue to receive nutrients via canaliculi, which connect various osteocytes to one another

#23

Front (Question)

compact bone function

Back (Answer)

densely pack concentric rings of matrix are ideal for resisting compressive forces

#24

Front (Question)

spongy bone function

Back (Answer)

open spaces for the trabeculated network of this bone allow it to support shifts in weight distribution
