1

list the types of bones

long bone, short bones, flat bones, irregular bones

2

diaphysis

central part of the bone

3

metaphysis

most narrow part of the bone

4

epiphyses

end part of the bone

5

periosteum

Dense white fibrous membrane , around the end of the bones

6

articular cartilage

smooth white tissue covering the end of the bone.

7

medullary cavity

marrow cavity, the central cavity of the bone

8

osteoblast

makes new bone

9

osteoclast

breaks down brittle or damaged bone

10

osteocytes

nourishment and protection for the bone

11

Fibrous joints

They don’t move. connected by fibrous tissue

12

cartilaginous joints

little movement, connected by cartilage

13

synovial joins

lots of movement

14

particular cartilage

surround the end of each bone in the joint inside the synovial fluid

15

neurotransmitter for muscles

ACH

16

is k+ inside or outside the cell

inside

17

is NA+ inside or outside the cell

outside

18

during polarity what happens to the NA+ cells

they go into he icf making the concentration in the cell more positive

19

when k+ leaves the cell what is this called

hypopolarisation

20

how does calcium relate to bones

bone store calcium

21

myosin and actin

proteins responsible for the movement of skeletal muscle

22

2 types of cartilage and responsible or

elastic - shock resistant during movement

23

5 synovial joints are

1. ball and socket
2. pivet
3. saddle
4. gliding
5. hinge

24

the proteins responsible for muscle contraction

tropomyosin troponin

25

where is the ca stored and where is it released from

SR which is inside the ICF
