Q

What is homeostasis?

A

Biological balancing. It indicates a state of dynamic equilibrium in which internal conditions vary within narrow limits.

27
Q

What are narrow limits called?

A

Set points

28
Q

What is homeostasis control?

A

All homeostasis control mechanisms have at least 3 interdependent components for the variable being regulated

29
Q

What are the 3 interdependent component in homeostasis?

A

1) receptors 2) control centre 3) effector

30
Q

What is the role of receptors?

A

The receptor is the sensing component that monitors and responds to changes in the environment. When the receptor senses a stimulus, it sends information to a control centre

31
Q

What is the role of the control centre?

A

The control centre is the component that sets the range at which a variable is maintained and determines an appropriate response to the stimulus

32
Q

What is the role of effector?

A

The receptor thus stimulated then responds by either enhancing the stimulus with positive feedback or depressing it with negative feedback

33
Q

What is positive feedback mechanisms?

A

This mechanism is positive because the results are in the same direction as the initial change. Positive feedback is used to control infrequent events that do not require constant adjustments

34
Q

What is negative feedback mechanisms?

A

These cause the variable to change in direction opposite to the initial change to return to the ‘ideal’ value

35
Q

What is an example of positive feedback?

A

Formation of a platelet plug

36
Q

What is an example of negative feedback?

A

rising blood glucose level

37
Q

What is the anatomical position of the body?

A

the body is erect with feet slightly apart, the palms of the hands facing forwards and the thumbs pointing outwards

38
Q

What does superior mean?

A

Towards the head or upper part of the body e.g. the head is superior to the abdomen

39
Q

What does inferior mean?

A

Away form the head or towards the lower part of the body e.g. the navel is inferior to the chin

40
Q

What does ventral (anterior) mean?

A

Towards or at the front of the body e.g. the breastbone is anterior to the spine

41
Q

What does dorsal (posterior) mean?

A

Towards or at the back of the body e.g. the heart is posterior to the breastbone

42
Q

What does medial mean?

A

Towards or at the midline of the body e.g. the heart is medial to the arm

43
Q

What does lateral mean?

A

Away from the midline of the body e.g. the arm are lateral to the chest

44
Q

What does intermediate mean?

A

Between a more medial and a more lateral structure e.g. the collarbone is intermediate between the breastbone and shoulder

45
Q

What does proximal mean?

A

Closer to the origin of the body part of the point of attachment of a limb to the body trunk e.g. the elbow is proximal to the wrist

46
Q

What does distal mean?

A

Farther from the origin of the body part or the point of attachment of a limb to the body trunk e.g. the knee os distal to the thigh

47
Q

What does superficial (external) mean?

A

Towards or at the body surface e.g. the skin is superficial to the skeletal muscles

48
Q

What does deep (internal) mean?

A

Away from the body surface e.g. the lungs are deep to the skin

49
Q

The study of how the body functions is called?

A

Physiology

50
Q

The study of the body structure is called?

A

Anatomy

51
Q

A midsagittal section through the head would divide?

A

The right eye form the left eye

52
Q

What are the 2 main body divisions?

A

Axial - head, neck and trunk

Appendicular - limbs attached to the axis

53
Q

A frontal section through the head would divide?

A

The nose from the back of the head

54
Q

A transverse section though the elbow would divide?

A

The shoulder from the hand

55
Q

What does the middle abdominal regions include?

A

Right and left lumbar and umbilical

56
Q

What does the lower right abdominopelvic quadrant include?

A

All of the right iliac region

57
Q

Which of the abdominal region can be found in each of the 4 quadrants?

A

The umbilical

58
Q

What does the lower abdominopelvic region include?

A

The right and left iliac and hypogastric

59
Q

What are most of the organs in the ventral cavity partly or completely covered by?

A

Serous membrane

60
Q

What is the layer of membrane lining the cavity wall called?

A

Parietal membrane

61
Q

What is the membrane covering the organs called?

A

Visceral membrane

62
Q

What is the heart covered by?

A

Pericardium

63
Q

What are the lungs covered by?

A

Pleura

64
Q

What are the abdominal organs covered by?
