1

Axial skeleton

The bones that form the longitudinal axis of the body

2

Appendicular skeleton

The bones of the limbs and girdle

3

Skeleton system

Includes the joints cartilage and ligaments

4

Functions of the bone

Support, protection, movement, storage and blood cell formation

5

Classification of bone

Compact bone spongy bone long bones, short bones, flat bones irregular bones

6

Compact bone

Dense and looks smooth and homogeneous

7

Spongy bone

Composed of small needle like pieces of bone and lots of holes

8

Long bone

Longer than they are wide and are mostly compact bone. All bones of the limbs except the patella and the wrist and ankle bones

9

Flat bones

Thin, flattened and usually curved. Most bones of the skull, the ribs, and the sternum are flat bones

10

Irregular bones

The vertebrate, which make up the spinal column, and the hip bones.

11

What is the relationship between muscle function and bones?

Muscles use bones as levers to bring about body movement

12

Diaphysis

Or shaft makes up most of the bone's length and is composed of compact bone

13

Periosteum

The diaphysis is covered and protected by a fibrous connective tissue membrane

14

Perforating

Hundreds of connective tissue fibers

15

Epiphyses

Ends of long bone

16

Articular cartilage

Covers the external surface of the epiphysis. Glassy hyaline cartilage, it provides a smooth, slippery surface that decreases friction at joint surfaces

17

Epiphyseal line

In adult bone there is A thin line spanning the epiphysis that looks a bit different from the rest of the area.

18

Epiphyseal plate

A flat plate of hyaline cartilage seen in young growing bone. Causes the lengthwise growth of a long bone

19

Yellow marrow or medullary cavity

In adult cavity of the shaft is primarily a storage of adipose tissue.

20

Red marrow

In infants this area forms blood cells

21

Osteocytes

Mature bone cells

22

Lacunae

Osteocytes are found within the matrix in tiny cavities

23

Lamellae

The lacunae are arranged in concentric circles

24

Central canal

Surrounds the lamellae

25

Osteon

Complex consisting of central canal and matrix rings

26

Canaliculi

Tiny canals. Radiate outward from the central canals to all lacunae

27

What is the anatomical name for thru shaft of a long bone

Diaphsis

28

What is the importance of canaliculi?

They carry nutrients to the bone cells

29

Ossification

Bones form using hyaline cartilage structures as their models

30

Osteoblast

Bone forming cells

31

Osteoblasts

Bone-destroying cells in bones

32

Bones don't start as bones. What do they begin as?

Membranes or cartilage

33

Tuberosity

Large, rounded projection may be roughened

34

Crest

Narrow ridge or bone; usually prominent

35

Trochanter

Very large, blunt, irregularly shaped process ( the only examples are on the femur)

36

Line

Narrow ridge of bones; less prominent than a crest

37

Tubercle

Small, rounded projection or process

38

Spine

Sharon, slender, often pointed projection

39

Process

Any bony prominence

40

Head

Bony expansion carried on a narrow neck

41

Facet

Smooth, nearly flat articular surface

42

Condyle

Rounded articular projection

43

Ramus

Armlike bar of bone

44

Groove

Furrow

45

Fissure

Narrow, slitlike opening

46

Foramen

Round or oval opening through a bone

47

Notch

Indentation at the edge of a structure

48

Meatus

Canal-like passageway

49

Sinus

Cavity within a bone, filled with air and lined with mucous membrane

50

Fossa

Shallow, baseline depression in a bone, often serving as an articular surface

51

Skull

Formed by 2 sets of bone. Facial and cranium

52

Cranium

Frontal bone, parietal bone, temporal bone,occipital bone, sphenoid bone and ethmoid bone

53

Facial bones

Maxillae, palatine bones, zygomatic bones, lacrimal bones, nasal bones, vomer bone, inferior nasal conchae, and mandible

54

Hyoid bone

Closely related to the mandible and temporal bones. It is unique in that it is the only bone that does not articulate directly with any other bone. Moveable base for the tongue

55

Fontanels

Fibrous membranes connecting the cranial bones

56

What are the 3 main parts of the axial skeleton?

Skull, vertebral column, and bony thorax

57

Only joints in the skull that are freely moveable

These are the temporomandibular joints

58

Which skull bone form the "keystone of the face"

Maxillae

59

Which bone has the cribriform plate and the crista galli?

Ethmoid bone

60

Which bones are connected by the coronal suture? By the sagittal suture?

Frontal joins with the parietals at the coronal suture. Parietals joins one another at the sagittal suture
