pectoral girdle: scapula

shoulder blades. triangular, and are wing shaped. posterior side has a spine (protruding thingy)

2

scapula: acromion process

roughened end of the spine of the scapula, connects with clavicle

LATERAL

3

scapula: coracoid process

beaklike process, near acromion

4

scapula: glenoid cavity

on lateral edge, articulates with humerous

5

scapula: superior border

superior

6

scapula: lateral border

lateral

7

scapula: medial border

medial side

8

scapula: spine

the thing that protrudes from the posterior side

9

scapula: supraspinosus fossa

superior part of the flat piece

10

scapula: infraspinosus fossa

inferior part of the flat piece

11

pectoral girdle: clavicle

collarbone

12

clavicle: acromial end

attaches to scapula to form part of the shoulder joint - rounded

13

clavicle: sternal end

attaches to sternal manubrium

looks flat if you look at it straight on.

14

humerus

upper arm bone.

15

humerus: head

head fits into glenoid cavity of the scapula.

16

humerus: greater tubercle

on anterior, it's the lateral side , same side as deltoid tuberosity.

17

humerus: lesser tubercle

on anterior, medial side, not visible from posterior view.

18

humerus: deltoid tuberosity

midpoint of shaft, where deltoid attaches
lateral side.

19

humerus: lateral epicondyle

lateral posterior (right side, when looking at posterior view)

20

humerus: medial epicondyle

medial in both anterior and posterior view

21

humerus: capitulum

articulates with radius of arm

22

humerus: trochlea

looks like a spool, bigger part is visible from anterior side

23

humerus: coronoid fossa

anterior hole - works with ulna

24

humerus: olecranon fossa

posterior hole - works with ulna

25

ulna

medial bone of the forarm

26

ulna: olecranon + coronoid process

olecranon (superior) and coronoid (anterior) - these grip the humerus at the trochlea

27

ulna: trochlear notch

part which grips the trochlea in a plierslike joint

28

ulna: radial notch

articulates with head of radius

29

ulna: head

distal end (bottom of bone)

30

ulna: styloid process

medial - has a little nub which attaches to the ligaments of the wrist.

31

radius

lateral bone of the forearm

32

radius: head

proximal which articulates with the capitulum of the humerus

33

radius: radial tuberosity

proximal and just below head, point of attachment for tendon of the biceps muscle of the arm

34

radius: ulnar notch

distal, articulates with end of ulna

35

carpals

8 wrist bones, irregular bones.

36

metacarpals

5 bones which connect the wrist bones to the phalanges. when you make a fist and you see knuckles, they are the metacarpal bones.

37

phalanges

digits. each finger has 3 except thumb: proximal, middle, distal

38

pelvic girdle: coxal bones / ossa coxae

hip bones - together with sacrum & coccyx, form bony pelvis

39

coxal bone: ilium

forms major part of the coxal bone - top lateral flat section

40

coxal bone: iliac crest

superior margin of the iliac bone

41

coxal bone: Ischium

sit down bone, the most inferior and posterior portion of the coxal

42

coxal bone: ischial tuberosity

sit bones, lateral superior, underneath ischium

43

coxal bone: pubis

most anterior portion of coxal bone

44

coxal bone: acetabulum

huge socket on lateral side that attaches to thigh bone

45

coxal bone: obturator foramen

hole in the bottom part of the hip bone

46

coxal bone: symphysis pubis

cartilage between each hip bone at pubic crest

47

coxal bone: pubic arch

most inferior arch of the hip bone

48

femur

thigh bone, heaviest, strongest bone in the body.

49

femur: head

a ball at the top, medial side, attaches to hip bone via the acetabulum.

50

femur: fovea capitis

pit of the head, a small central pit in the head.

51

femur: Greater trochanter

lateral, at the junction of the shaft and the neck

52

femur: lesser trochanter

medial, separated from greater trochanter by intertrochanteric crest

53

femur: linea aspera

ridge on posterior view

54

femur: lateral & medial condyle

visible from posterior view, articulates with tibia.
smooth parts of the distal part of the bone

55

femur: lateral & medial epicondyle

superior to condyles, they are the sides of the distal part of the bone. on the side of condyles

56

patella

triangular sesmoid bone

57

tibia

shin bone, larger, more medial lower leg bone.

58

tibia: medial + lateral condyle

proximal end, receive distal end of femur to form knee joint.

59

tibia: tibial tuberosity

anterior view, protrusion and site of attachment of patella

60

tibia: medial malleolus
