muscular system

Question 1

list the functions of the skeleton

Answer 1

Support (hard/soft tissue)
Protection
production of re blood cells
storeage of ions and minirals
movement (levers)

Question 2

what are the two bone types

Answer 2

Compact
Cancellous

Question 3

characteristics of compact bone

Answer 3

strong in 1 direction, good for moving forces down this structure

Question 4

characteristics of cancellous bone

notstructure: what its good at doing

Answer 4

shock absorbant
good at chanalling forces from multiple directions
lightweight

Question 5

what are the 4 bone classes
and how do you identify them

Answer 5

Long bones, long diaphyis which leads to a wider epephyis, compact bone mostly
Short bones, simlar length and width, mostly cancellous bone, weightbearing multiple directions
Flat bones, thin plates, a thin layer of compact bone mostly shock absorbing cancellous bone inside. good to attach muscels to and good protection
irregular bones, everything else often has holes for body parts

Question 6

what are the two parts of the skeleton

Answer 6

axial
appendicular

Question 7

what bones are in the axial skeleton

Answer 7

thorasic 12
lumbar 5
sacrum
coccyx`

Question 10

thorax

Answer 10

ribs 12
2 floating, 10 attached
sternum

Question 11

Answer 11

Limbs-
arm, forearm
thigh, leg
hands/feet

Question 12

main bones in your limbs

Answer 12

humerous, radii and ulner
femur, fibia and tiba (larger)

Question 13

what attaches you legs/arms to your body

Answer 13

pelvic girdle
pectoral girdle

Question 14

bones in pectoral girdle

Answer 14

clavical
scapular

Question 15

bones in pelvic girdle

Answer 15

sacrum
hip -
iscium, pubis, ilium

Question 16

sexual diamorphisum + example

Answer 16

a diffrence in men and womens physiology
in woman the pelvus is wider and more round with a shallowerer angle in the pubic arch

Question 17

why is the fibia/tibia/femur more secuar than the radii/ulner/humorus

Answer 17

the legs and thigh have to support the weight of the trunk. deep femur attachment to the pelvic gerdle limit movement and improves strength.
the arms are more mobile to help with movement.

Question 18

bones of the hands

Answer 18

carpals (8)
metacarpals (5)
phlanges (14)

Question 19

bones of the feet

Answer 19

tarsals (7)
metatarsals (5)
phlanges(14)
