cushion, and movement

Question 13

What are joints?

Answer 13

The place where two bones meet, where allows degrees of movement

Question 14

3 types of joints

Answer 14

fibrous
cartilaginous
synovial

Question 15

What are fibrous joints?

Answer 15

Dense material as bones
very strong, connects
allows no movement
EX: sutures, where the skull forms

Question 16

What are cartilaginous joints?

Answer 16

cartlage that physically holds the bones together
softer then bone but still not a ligament
allows for partal movement in joint
EX: vertebral disc

Question 17

What are Synovial joints?

Answer 17

cushined by cartiledge but held together by ligments
also joint cavity filled with synoval fluid to reduce fricyyion, LUBE
EX: Elbow

Question 18

gliding joints

Answer 18

description
allow the flat surfaces of bones to slide over each other; give you the ability to walk on uneven surfaces and move your hand to the right and left
ex: ankle

Question 19

pivot joints

Answer 19

where two bones turn on each other and allow for rotation of a body part
EX; figit spinner

saddle joints

Answer 20

allows a bone to move front to back and left to right; more limited movement than a ball-and-socket joint
EX: thumb

hinge joints

Answer 21

allows bones to move in one direction only, like a swinging doo
EX: Knee

Question 22

ball-and-socket joints

Answer 22

the knoblike end of one bone fits into the cup-like end of another; allows movement in almost any direction

Answer 24

BOnes contribe to homeostasis by producing blood cells and acting as a storage bank for various minerals- calcuim

Question 25

Three layers of Bone

Answer 25

Periosteum
compact bone tissue
spongy bone tissue

Question 26

Periosteum

Answer 26

Protective tissue that holds and protects blood vessles that bring nuterients to and remover aste from the bone

Question 27

compact bone tissue

Answer 27

It is made of rings of calcium, in the centre are called a Haversian canel through which a small blood vessle can run

Question 28

spongy bone tissue

Answer 28

It holds and protects red and yellow bone marrow
Red bone marrow produces red blood cells,
Yellow bone marrow is primarily fat

Question 29

Osteoblasts

Answer 29

Removes calcium from the blood and depostis in the bone

Question 30

Osteoclasts
