Q

What does the 2nd R in MURDERS INC stand for?

A

Reproductive system

21
Q

What are the 2 categories of the reproductive system?

A
  1. Self producing (cytogenic)
  2. Hormone producing (endocrinic)

We are primarily concerned with the hormone producing side because those hormones aid the nervous system in its regulatory role.

22
Q

What does the S in MURDERS INC stand for?

A

Skeletal System - consists of bones, cartilage and ligaments.

23
Q

What are the 3 things the skeletal system does?

A

  2. permits movement
  3. forms blood cells
24
Q

What does the I in MURDERS INC stand for?

A

Integumentary System - consists of skin, hair, fingernails and accessory structures.

25
Q

What are the main functions of the integumentary system?

A

protection of the body
control of body temp
excretion of wastes (i.e. through sweat)
sensory perception

26
Q

A

Nervous System

27
Q

What makes up the Nervous system?

  1. Brain
  2. Brain Stem
  3. Spinal cord
  4. nerves
28
Q

What does the nervous system do?

A

controls, coordinates and integrates all physiological processes so that normal body functions can be maintained.

29

A

Blood

34
Q

What are the 3 parts of a neuron?

A
  1. cell body
  2. axon
  3. dendrite
35
Q

What does the Axon (part of the neuron) do?

A

sends out the neurotransmitter (also known as the chemical messenger)

36
Q

What does the dendrite do?

A

part that receives the neurotransmitter

37
Q

The gap between two neurons is called a ________

A

Synapse or synaptic gap

38
Q

Nerves that carry messages AWAY from the brain are called _____________ Nerves

A

Motor or efferent nerves

39
Q

Afferent (sensory) nerves do what?

A

Carry carry messages TO the brain

40
Q

What are the 2 sub-systems of motor nerves?

A

Voluntary- Send messages to the muscles that we control

Automatic nerves- Sends messages to nerves we muscles/organs we don’t control

41
Q

What nerves control the body fight or flight response such as blood pressure to elevate and sweat glands to activate?

A

Sympathetic nerves

42
Q

What nerves control the body relaxed tranquil activates such as heartbeat slowing and blood pressure to decrease?

A

Parasympathetic nerves

43
Q

What drugs bring up the body that may be low in some things like low blood pressure?

A

Sympathetic (adrenergic) drugs

44
Q

Parasymphetic (cholinergric) drugs do what?

A

bring down the body that may be high in some things like high blood pressure?

45
Q

What is the downside effect?

A

When the body respond to the presence of a drug by releasing hormones to counteract the effects of the drug consumed to return to homeostasis.

46
Q

negative feedback

A

When the body stops producing the hormones and neurotransmitters due to dependence on a frequent drug that is commonly put into the body. The user then depends on that drug to produce those things.

47
Q

What is the chemical changes that take place when the drug reacts with enzymes and other substances in the body? (i.e. Heroin being metabolized into the body turns into morphine)

A

Metabolite

48

A

Pulmonary vein

49
Q

What does the pulmonary artery do?
