elevation - superior movement

depression - inferior movement

30
Q

What is the difference between internal and external rotation?

A

internal - towards midline

external - away from midline

31
Q

What is circumduction?

A

sequential flexion abduction, extension, adduction (circular movement)

32
Q

What is the difference between inversion and eversion?

A

inversion - sole of foot towards median plane

eversion - sole of foot away from median plane

33
Q

What is the difference between plantar flexion and dorsiflexion?

A

plantar flexion - toe up

dorsiflexion - toe down

34
Q

What is the difference between supination and pronation?

A

supination - rotating radius laterally, uncrossing from ulna

pronation - rotates radius medially

35
Q

What is opposition?

A

thumb to pad of another finger

36
Q

What is the difference between finger abduction and adduction?

abduction - away from middle finger

adduction - towards middle finger

37
Q

List three articular surface features of bone

A

facets/fovea, condyles, trochlea

38
Q

List three elevations of bone

A

process, spine, tubercle, crest, epicondyle, head

39
Q

List three depressions of bone

A

fossa, sulci, canals, apertures

40
Q

What are the three types of joints?

A

synovial, fibrous, cartilaginous

41
Q

Features of fibrous joints

A

sutures of cranium, not much movement

42
Q

Features of cartilaginous joints

A

hyaline cartilage

primary (allows for bone growth) and secondary (inter-vertebral discs)

43
Q

Features of synovial joints

A

joint cavity: lined by synovial membrane which produces synovial fluid for lubrication
articular cartilage: hyaline cartilage, protection from friction
articular capsule: fibrous, provides stability and structure, thick parts = ligaments

44
Q

Types of synovial joints

A
  • ball-and-socket
  • saddle
  • condyloid/ellipsoid
  • plane
  • pivot
  • hinge
45
Q

Ball-and-socket

A

flexion and extension, abduction and adduction, medial and lateral rotation
eg hip and shoulder

46
Q

Saddle

A

flexion and extension, adduction and abduction

eg thumb

47
Q

Condyloid/ellipsoid

A

rounded surface in a concave surface

flexion and extension, abduction and adduction

48
Q

Hinge

A

flexion and extension in the sagittal plane

eg shoulder

49
Q

Pivot

A

rotation around a central axis

eg C2 and C3 vertebrae

50
Q

Plane

A

sliding and gliding

scapula and clavicle

51
Q

Isometric vs isotonic

A

Isometric: muscle changes length in relationship to production of movement
Isotonic: muscle length remains the same; no mvement occurs but firce is increased to resist gravity

52
Q

Concentric vs eccentric

A

Concentric: movement occurs as a result of muscle shortening
Eccentric: contracting muscle lengthens

53
Q

What are the three types of muscles?

A

Skeletal, cardiac and visceral

54
Q

Skeletal muscle features

A

voluntary, striated, attached to bone to cause voluntary movement

55
Q

Cardiac muscle features

A

striated, involuntary, intercalated discs

56
Q

Visceral muscle features

A

involuntary, smooth, organs

57
Q

What is a motor unit?

A

a single motor neuron and the muscle fibres innervated by it

58
Q

Define agonist

A

main muscle/s responsible for movement

59
Q

Define antagonist

A

opposes action of agonist

60
Q

Define synergist

A

assists movement

61
Q

Define stabiliser/fixator

A

dynamic stabilisers of a joint

62
Q

Define shunt

A

resists dislocating forces

63
Q

What are the three types of connective tissue. Give a description for each.

A

Tendons: muscle to bone, epi+peri+endomyium
Aponeurosis: collagen as flat sheets which anchor muscle to skeleton
Fascia: covers most of the body deep to skin

64
Q

How many pairs of spinal nerves are there?

A

31

65
Q

What type of matter is cell bodies and axons?

A

Cell bodies: gray matter

Axons: white matter

66
Q

Where is white and gray matter located in the spinal cord?

A

White = out, gray = in

67
Q

Other names for efferent nerves

A

motor, anterior

68
Q

Other names for afferent nerves

A

sensory, posterior
