45
Q

2 Divisions of the Skeletal System

A

Axial

Appendicular

46
Q

Axial

A

Central core of the skeletal system

47
Q

Appendicular

A

Includes the bones of the upper and lower limbs and bones that attach the limbs to the axial skeleton

48
Q

3 types of Cartilage

A

Hyaline (joints)
Elastic (ear)
Fibrocartilage (discs of spinal column)

49
Q

2 types of Bones

A

Compact bone

Spongy/cancellous/trabecular bone

50
Q

Compact bone

A

Superficial thin layer provides the strength to bones for weight bearing; larger proportion of compact bone is found at the ends of the bones

51
Q

Spongy/cancellous/trabecular bone

A

Found deep to compact bone and superficial to the marrow cavity if present, contains many small spaces

52
Q

Classifications of Bones (5)

A

Long: Are tubular in shape (i.e. humerus and femur)
Short: Are cuboidal in shape and found in the wrist (i.e.carpal bones)
Flat: Protective function (i.e. skull bones)
Irregular: Various shapes (i.e. bones of the face, vertebrae)
Sesamoid: Develop in certain tendons (i.e. patella and sesamoid bones of the 1st toe)

53
Q

Accessory bones:

A

Extra bones which are small, irregular in shape and often found in the sutures of the skull bones. These are also commonly seen in the foot

54
Q

Parts of a Typical Long Bone (4)

A

Epiphysis
Metaphysics
Diaphysis
Epiphyseal plate

55
Q

Epiphysis

A

The end of a long bone

56
Q

Metaphysics

A

The region between the epiphysis and the diaphysis

57
Q

Diaphysis

A

The shaft of the long bone

58
Q

Epiphyseal plat

A

In adults this is a remnant line where the epiphyseal plate (growth plate) was in the child or developing bone

59
Q

Depressions (bones)

A

allow passage of materials, form joints

60
Q

Openings (bones)

A

allow passage of materials, form joints

61
Q

Processes (bones)

A

provide attachment for muscles and ligaments

62
Q

Projections (bones)

A

provide attachment for muscles and ligaments

63
Q

Fossa (bone depression)

A

Shallow depression in bone, houses opposing bone during flexion

64
Q

Sulcus (bone depression)

A

Furrow along bone, holds tendon or blood vessal

65
Q

Foramen (bone openings)

A

Opening in bone, nerves and blood vessels pass through

66
Q

Fissure (bone openings)

A

Narrow slit between 2 adjacent bones, nerves and blood vessels pass through

67
Q

Canal (bone openings)

A

Large opening in center of bone

68
Q

Sinus (bone openings)

A

Cavity or chamber within bone

69
Q

prominent ridge or elongated projection

74
Q

Line (bone projection)

A

long narrow ridge, less prominent than crest

75
Q

Spine (bone projection)

A

small pointy projection

76
Q
