Test 2 - Skelteal System

Question 1

Tissue Types - Epithelial

Answer 1

lines cavities, cover surfaces

Question 2

Tissue Types - Connective

Answer 2

GPS
ground substance
proteins
specialized cells

Question 3

Tissue Types - Muscular

Answer 3

moves other body tissues

Question 4

Tissue Types - Nervous

Answer 4

conducts electrical signals

Question 5

Functions of Bones - Movement

Answer 5

bones interact with skeletal muscles to maintain or change the position of body parts

Question 6

Functions of Bones - Support

Answer 6

bones support and anchor muscles

Question 7

Functions of Bones - Protection

Answer 7

many bones form hard compartments that enclose and protect soft internal organs

Question 8

Functions of Bones - Mineral Storage

Answer 8

bones are a reservoir for calcium and phosphorous, deposits/withdrawals of mineral ions maintain proper concentrations in body fluids

Question 9

Functions of Bones - Blood Cell Formation

Answer 9

some bones contain marrow where blood cells are produced

Question 10

Movements of the Body

Answer 10

flexion: decrease in joint angle

extension: increase in joint angle

hyperflexion: moving past normal amount of flexion

Question 11

Integumentary System

Answer 11

skeleton provides support
for skin and the muscles below it.

Question 12

Muscular System

Answer 12

skeletal muscles attach to bones, which serve as levers for body movements

bone calcium may be released as needed to maintain blood levels required for muscle contractions.
The skeleton provides support
for skin and the muscles below it.

Question 13

Respiratory System

Answer 13

rib cage and sternum protect the lungs, muscles used in breathing attach to ribs and associated cartilages

Question 14

Urinary System

Answer 14

rib cage partially protects the kidneys, pelvis helps protect the bladder

Question 15

Nervous System

Answer 15

skull protects the brain, vertebrae protects the spinal cord

bone calcium stores may be
released as needed to maintain blood levels required for transmission of nerve impulses

Question 16

Digestive System

Answer 16

bone stores dietary calcium and
phosphorus, bones of the rib cage and pelvis protect organs including the stomach, liver, and intestines

facial bones have sockets for teeth

Question 17

Cardiovascular System and Blood

Answer 17

bone calcium is available for heart
contractions that pump blood, all types of blood cells form in red bone marrow

Question 18

Immunity and the Lymphatic System

Answer 18

white blood cells that function in body
defenses form in bone marrow

Question 19

The Skeletal System

Answer 19

skeleton supports and helps protect soft body parts, bones joints, tendons, and ligaments all have essential
roles in moving the body and its parts

bone is a reservoir for calcium, which is vital for many body functions including muscle contractions, the transmission of nerve impulses, and blood clotting

calcium also is required for
the proper functioning of some
enzymes and of proteins in the
cell plasma membrane

Question 20

Sensory Systems

Answer 20

skull and facial bones surround and protect sensory organs in the head, calcium in bones helps maintain blood levels required for transmission of sensory nerve impulses

Question 21

Endocrine System

Answer 21

calcium may be released as needed
to maintain blood levels required for the formation and secretion of many hormones

Question 22

Reproductive System

Answer 22

pelvic bones protect female reproductive organs and associated glands in males, calcium is available to help nourish a fetus and for milk production in a nursing mother

Question 23

Blood as Connective Tissue

Answer 23

blend of living cells and matrix that contains protein fibers, like collagen and calcium

Question 24

Bone Remodeling

Answer 24

bone tissue is constantly remolded, calcium continually enters and leaves bones which helps bone tissue become resilient

when bone is subjected to mechanical stress, more bone is deposited than removed

bone remodeling helps meet demands for dietary calcium

Question 25

Medical Terminology

Answer 25

oste/o: bone

-blast: typically a builder, immature cell

fibr/o: fibers; usually protein fibers

-cyte: cell

chondr/o: cartilage
