1

describe a bone

there are 2 epiphysis, one is the head, and a diaphysis (shaft) in between
there is a marrow cavity in the diaphysis
there is an epiphyseal plate in between the diaphysis and both epiphysis
compact bones surrounds the marrow cavity and cancellous bone
periosteum surrounds most of the bones with the exception where there is articular cartilage

2

what are the 3 classifications of joint?

synovial
fibrous
cartilaginous

3

describe a synovial joint

extensive movement
smooth cartilage
synovial fluid in capsule
eg. shoulder, knee

4

describe a fibrous joint

no synovial cavity
joint held together by dense CT eg. skull

5

describe a cartilaginous joint

no synovium
little movement held together by cartilage eg. pelvis

6

describe the components in a synovial joint

bones:
articular (hyaline) cartilage
marginal (fibro) cartilage
synovial fluid
joint capsule
ligaments:
musculotendinous support
tendons
muscles to move joint

7

where do fibrous joints occur?

sutures of skull-no movement
syndesmoses
greater distance between articular surface
more dense CT
distal tibia & fibula

8

where do cartilaginous joints occur?

pelvis, sternum, ribs
bone ends covered by hyaline cartilage, disc of fibrocartilage in between

9

describe the vertebral column

cervical
C1-C7
thoracic
T1-T12
lumbar
L1-L5
sacrum
5 segments

10

what are the 2 parts of the sternum?

sternum manubrium
sternum body

11

what is the joint between the sternum and clavicle?

sterno-clavicular joint

12

what is the joint between the clavicle and shoulder?

acromio-clavicular

13

what are the pubic bones?

iliac
superior pubic ramus
pubic
inferior pubic ramus
ischium

14

what is the upper arm bone?

humerus

15

what is the shoulder bone?

scapula

16

what is the glenoid fossa?

shoulder socket

17

what are the lower arm bones?

radius and ulna

18

describe the bones of the hand

8 carpal bones
5 metacarpals
14 phalanges (fingers)

19

describe the femur joint -hip

femoral head
neck
greater tuberosity
lesser tuberosity
acetabulum-socket

20

describe the knee

femus
femoral condyle medial
femoral condyle lateral
patella
tibia
fibula

21

describe the ankle

tibia-> medial malleolus
fibula-> lateral malleolus
talus

22

what is the heel bone?

calcaneus

23

describe the feet bones

tarsal bones
metatarsals
phalanges
