Flashcards in The Axial Skeleton Ch 3 Deck (53):
1

Axial Skeleton

The framework of the body that includes the skull, auditory ossicles, hyoid bones, vertebral column, ribs and sternum

2

Appendicular Skeleton

The framework of the body that consists of the extremities, shoulder, and pelvic girdle

3

Append

Add or hang

4

Cranium

The portion of the skull that encloses the brain

5

Frontal

Forms the front of the cranial cavity or "front" or cranial portion of the skull

6

Parietal

Paired bones that form the roof of the caudal cranial cavity

7

Occipital (Ohck-sihp-ih-tahl)

Forms the caudal aspect of the cranial where the foramen magnum, or the opening for the spinal cord, is located

8

Foramen

An opening in bone through which tissue passes

9

Magnum

means large

10

Temporal

Paired bone that form the sides and base of the cranium

11

Sphenoid

Paired bones that form part of the base of the skull and parts of the floor and sides of the bony eye socket

12

Ethmoid

Forms the rostral part of the cranial cavity

13

Incisive

Forms the rostral part of the hard palate and lower edge of nares

14

Ptergoid (tahr-ih-goyd)

Forms the lateral wall of the nasopharynx

15

Zygomatic

Forms the orbit and cheekbone; projections from the temporal and zygomatic bone form the zygomatic arch (cheekbone)

16

Zygomatic Arch

The cheekbone

17

Maxilla

21

Nasal

Forms the bridge of the nose

22

Vomer

Forms the base of the nasal septum

23

Nasal Septum

The cartilaginous structure that divides the two nasal cavities

24

Hyoid

Bone suspended between the mandible and the laryngopharynx

25

Vertabral Column (spinal column or backbone)

Supports the head and body and protects the spinal cord

26

Vertebra (plural vertebrae)

Individual bones that the vertabral column consists of

27

Vertebr/o or spondyl/o (combining form)

Vertebra (plural vertebrae)

28

The 'body' of the vertebra

The solid portion ventral to the spinal cord

29

The 'arch' of the vertebra

The dorsal part of the vertebra that surrounds the spinal cord

30

The lamina (lahm-ih-nah)

The left or right dorsal half of the arch. Processes project from the vertebra

31

Process

Projection

32

Spinous Process

A single projection from the dorsal part of the vertebral arch

33

Transverse Processes

Project laterally from the right and left sides of the vertebral arch

34

Articular Process

Paired cranial and caudal projections located on the dorsum of the vertebral arch

35

Foramen

Means Opening

36

Vertebral Foramen

The opening in the middle of the vertebra through which the spinal cord passes

37

Intervertebral discs

Cartilage discs that cushion and separate the vertebrae from each other

38

Disc/o (combining form)

Discs

39

'Cervical Vertebral region'

40

'Thoracic Vertebral region'

Chest area 'T' of the vertebra

41

'Lumbar Vertebral region'

Loin area 'L' of the vertebra

42

'Sacral Vertebral region'

Sacrum area 'S' of the vertebra

43

'Coccygeal (also known as caudal) Vertebral region'

Tail area 'Cy' or 'Cd'

44

Atlas

C1 or Cervical vertebra one - the first vertebra

45

Axis

46

Ribs

Paired bones that attach to the thoracic vertebrae

47

Cost/o (combining form)

Rib

48

Costals

49

Sternum

(Breastbone) Forms the midline ventral portion of the rib cage (Divided into 3 parts)

50

Manubrium (mah-nu-bre-uhm)

The cranial portion of the sternum

51

The 'body' of the sternum

The middle portion

52

Xiphoid Process

The caudal portion of the sternum

53

Thoratic Cavity (rib cage)

Protects the heart and lungs. Boundaries made up of the ribs, sternum and thoracic vertebrae
