Flashcards in Chapter 19 - The Skeleton Deck (70):
1

axial skeleton

Forms the central core "axis" of the body's framework.
Includes the skull, spinal column, and thorax.

2

skull

Region: cranium, facial portion, hyoid, and ossicles.

3

cranium

8 cranial bones.
Encloses the brain, houses the ear and forms part of the eye socket.

4

facial portion

14 facial bones.
Form the face and chambers for sensory organs.

5

hyoid

U-shaped bone under mandible (lower jaw); used for muscle attachments.

6

ossicles

3 ear bones.
Transmit sound waves through middle ear.

7

vertebral column

Encloses the spinal cord.
26 vertebrae (divided into 5 groups)
Cervical, thoracic, lumbar, sacrum, coccyx.

8

thorax

Sternum - anterior bone of the thorax
12 pairs of ribs - enclose the organs of the thorax.

9

appendicular skeleton

Attached "appended" to the axial skeleton.

10

appendicular skeleton
shoulder girdle

Clavicle - anterior; between sternum and scapula.
Scapula - posterior; anchors muscles that move arm.

11

appendicular skeleton
upper extremity

Contains: humerus, ulna, radius, carpals, metacarpals, and phalanges.

12

upper extremity - humerus

proximal arm bone

13

upper extremity - ulna

15

upper extremity - carpals

8 wrist bones

16

upper extremity - metacarpals

5 bones of palm

17

upper extremity - phalanges

14 bones of fingers

18

appendicular skeleton
lower division

pelvic bones and lower extremity

19

pelvic bones

2 os coxae.
Join sacrum and coccyx of vertebral column to form the bony pelvis.

20

appendicular skeleton
lower extremity

Contains: femur, patella, tibia, fibula, tarsal bones, metatarsals, and phalanges.

21
