Skeletal System

Question 1

a disease that causes brittle, fragile bones

Answer 1

osteoporosis

Question 2

degenerative joint disease

Answer 2

osteoarthritis

Question 3

bones that have a pronounced longitudinal axis

Answer 3

long bones

Question 4

cells that remove bone

Answer 4

osteoclasts

Question 5

osteocytes are star-shaped cells that maintain bone and are able to sense physical stresses. their long projections connect to each other through the canaliculi of bones

Answer 5

osteoblasts

Question 6

a group of diseases that affect collagen and result in fragile bones

Answer 6

brittle bone disease

Question 7

the contracting muscle in the pair of muscles that is involved in a given movement (agonist)

Answer 7

prime mover

Question 8

the relaxed muslce in the pair of muscles that is involved in a given movement

Answer 8

antagonist

Question 9

hyaline cartilage in long bone elongation happens (growth plate)

Answer 9

epiphyseal plate

Question 10

bones that are similar in both height and width, such as those found in the wrist. they have limited articulation with each other as gliding joints

Answer 10

short bones

Question 11

thin bones that have a plate-like shape, such as bones of the cranium

Answer 11

flat bones

Question 12

bones that don’t fit into the three bone shape categories : flat, long, short

Answer 12

irregular bones

Question 13

places in the skeletal system where bones meet other bones. some are movable, and some are immovable because the bones are fused together

Answer 13

joints

Question 14

point of articulation that allows for abduction, adduction, circumduction, and rotation
ex: hip socket

Answer 14

ball and socket joints

Question 15

joints such as those between the plates of the skull that do not allow motion

Answer 15

sutures

Question 16

tough connective tissue that attaches bone to bone

Answer 16

ligaments

Question 17

kind of connective tissue that protects bone in articulating joints

Answer 17

hyaline cartilage

Question 18

primary structural protein of connective tissue

Answer 18

cartilage

Question 19

a joint that allows for flexion and extension of the more distal bone along only one plane

Answer 19

hinge joint

Question 20

tubular structures that make up compact bone

Answer 20

osteons

Question 21

bone containing densely packed osteon that make up the peripheral layer of bone

Answer 21

compact (dense) bone

Question 22

star-shaped cells that maintain bone and are able to sense physical stresses

Answer 22

osteocytes

Question 23

microscopic pits in bones that contain osteocytes and connect to each other within an osteon by way of canaliculi

Answer 23

lacunae

Question 24

thin layer that surrounds bone and is the surface for attachment of tendons and ligaments

Answer 24

periosteum
