Metatarsal

Phalanges

1

Phalanges
(lower limb)

14 bones making the toes

2

Metatarsals
(Lower limb)

Five elongated bones that form the middle portion of the foot

3

Calcaneus

Heel bone

4

Talus

Moves freely where it joins the tibia and fibula

5

Tarsal

(Ankle)

Has seven bones

6

Fibula

Located on the lateral side of the tibia

7

Tibia

(Shinbone)

The larger of the two leg bones, located on the medial side

8

Patella

(kneecap)

Articulates with the femur

9

Femur

Longest bone in the body and extends from hip to knee

10

Upper limb

30 bones each upper limb

Humerus

Radius

Ulna

Carpals

Metacarpals

Phalanges


Provide attachment for muscles and function as delivers

11

Pelvic girdle

Consists of two coxal (ox coxae)

Articulate with each other anteriorly and the sacrum posteriorly

Provides attachments for the lower limbs

Protects urinary bladder, the distal end of the large intestine and the internal reproductive organs

12

Ilium

Largest and the uppermost portion of os coxae

13

Ischium

Lowest portion of os coxae and is L-shaped

14

Pubis

Makes up the anterior portion of os coxae

15

Phalanges
(Upper limb)

The finger bones

16

Metacarpals

Five, one in line with each finger

17

Carpals

Bound firmly in two rows of four bones

18

Ulna

Longer than the radius and overlaps the humerus

Located on the pinky side of the hand

19

Radius

Located on the thumb side of the hand

20

Humerus

Extends from scapula to the elbow

21

Scapula

"Shoulder blade"

Articulates with the clavicle and the humerus

22

Clavicle

Articulates with the sternum and the scapula

23

Pectoral girdle

Clavicle

Scapula

24

Ribs

12 pairs

True ribs: First 7 pairs articulate to the sternum

False ribs: Remaining 5 pairs attach indirectly to the sternum

Floating ribs: 11th and 12 pair
- they do not attach at all to the sternum

25

(Parts?)

"Breastbone"

Articulates with clavicle and ribs


Manubrium: Upper part

Body: Middle and largest part

Xiphoid process: Lower part

26

Thorax
(Consists of)

Consists of:

Sternum
Costal cartilage
Ribs
Thoracic vertebrae

27

Intervertebral disc

Located between each vertebrae, to support weight and absorb shock

28

Vertebral foramen

Spinal cord passes through

29

Spinous process

(Vertebral characteristic)

Extends posteriorly
