Q

name and explain the different types of body planes and sections

A

median(midsagittal) - cuts down the middle of the body (down the nose and through the naval)
sagittal plane- divides something into left and right parts (if it divides the entire body into left and right parts then it is midsagittal)

23
Q

essential for normal operation of the respiratory system and breathing

A

atmospheric pressure

24
Q

single substance accounting for more than 60% of body weight; provides the basis for body fluids of all types

A

water

25
Q

required for the release of energy from foodstuffs

A

oxygen

26
Q

appropriate body temperature

A

when too high or too low, physiological activities cease, primarily because molecules are destroyed or become nonfunctional

27
Q

what can a disturbance in homeostasis result in

A

illness

28
Q

positive feedback

A

increases the original stimulus to push the variable farther; causes an amplification of a response; in the body this occurs in the menstrual cycle, blood clotting, and birth of a baby (contractions)

29
Q

negative feedback

A

includes most homeostatic control mechanisms; shuts off the original stimulus, or reduces its intensity; provides a range of stability or a condition of “normal”; works like a household thermostat

30
Q

mediastinum

A

separates the lungs into right and left cavities in the thoracic cavity; houses the heart, trachea, and several other visceral organs

31
Q

approximately what percentage of the air we breathe is oxygen?

A

20%

32
Q

what covers an organ

A

visceral pericardium

33
Q

what lines cavities

A

parietal serosa

34
Q

what happens if the human body temperature drops belown 98.6 degrees F

A

metabolic reactions become slower

35
Q

which cavity houses the lung

A

pleural cavity

36
Q

which cavity houses the heart

A

pericardial cavity

37
Q

what does a PET do?

A

excels in observing metabolic processes

38
Q

What are the 6 levels of structural organization that make up the human body?

A
  1. Chemical level (atoms combine to make molecules)
  2. Cellular level (cells are made of molecules)
  3. ) Tissue level (tissues are made of similar types of cells)
  4. organ level (organs are made up of different types of tissues)
  5. organ system level(different organs working together)
  6. organism level (made up of various organ systems)
39
Q

anatomy levels of organization (9 in order)

A

atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism

40
Q

capability of the body to maintain a relatively constant environment

A

homeostasis

41
Q

examples of homeostatic mechanisms

A
  • shivering when the body temperature falls below normal levels
  • secreting insulin to decrease blood sugar concentration after a meal or whenever the blood sugar level is high
  • increasing heart rate and contraction force when blood pressure is low
42
Q

toward the head end or upper part of a structure or the body; above

A

superior (the forehead is superior to the nose)

43
Q

away from the head end or toward the lower part of a structure or the body; below

A

inferior (the navel is inferior to the breastbone)

44
Q

toward or at the front of the body; in front of

A

anterior (the breastbone is anterior to the spine)

45
Q

toward or at the backside of the body; behind

A

posterior (the heart is posterior to the breastbone)

46
Q

toward or at the midline of the body; on the inner side

A

medial (the heart is medial to the arm)

47
Q

away from the midline of the body; on the inner side of

A

lateral (the arms are lateral to the chest)

48
Q

close to the origin of the body part or the point of attachment of a limb to the body trunk

A

proximal (the elbow is proximal to the wrist)

49
Q

farther from the origin of a body part or the point of attachment of a limb to the body trunk

A

distal (the knee is distal to the thigh)

50
Q

toward or at the body surface

A

superficial (the skin is superficial to the skeleton)

51
Q

away from the body surface; more internal

A

deep (the lungs are deep o the rib cage)

52
Q

on the outside

A

peripheral (the ears are peripheral to the nose)

53
Q

towards the center

A

central (the nose central to the ears)

54
Q

dorsal body cavities

A

cranial cavity and spinal cavity

55
Q

ventral body cavities

A

thoracic cavity, abdominopelvic cavity (pelvic cavity & abdominal cavity)

56
Q

Explain the elements of a homeostatic control system

A
  1. STIMULUS produces a change in a variable
  2. RECEPTOR detects the change
  3. INPUT: information is sent along AFFERENT pathway to control center
    CONTROL CENTER analyzes info and determines the response
  4. OUTPUT: information is sent along EFFERENT pathway to EFFECTOR
  5. RESPONSE of effector feeds back to reduce the effect of stimulus and returns variable to homeostatic level
