Autonomic Nervous System

Question 1

Peripheral Nervous System divides into the…

Answer 1

1. Somatic Motor System

2. Autonomic (Visceral) Nervous System

Question 2

Autonomic Nervous System:

1. How many cell system?
2. Direct or Indirect control over target cell?
3. Myelinated or Unmyelinated?
4. Precise or Divergent?
5. Fast or Slow Conduction Velocity?

Answer 2

ANS (Visceral) can be PNS or SNS:

1. 2 CELL SYSTEM (Pre- and Postganglionic Neurons)
2. Indirect Control by Preganglionic Motor Neurons
3. Myelinated Preganglionic BUT Unmyelinated Postganglionic
4. Divergent Targeting
5. Slow conduction velocity

Question 3

Somatic Nervous System:

1. How many cell system?
2. Direct or Indirect control over target cell?
3. Myelinated or Unmyelinated?
4. Precise or Divergent?
5. Fast or Slow Conduction Velocity?

Answer 3

1. 1 Cell
2. Direct control over target (skeletal muscle) cells
3. Heavily Myelinated
4. Precise Targeting (Myotones)
5. Fast conduction velocity

Question 4

Splanchnic Nerves are considered to be Preganglionic or Postganglionic?

Answer 4

Splanchnic nerves are considered to be PREGANGLIONIC

Question 5

Cardiopulmonary Nerves are considered to be Preganglionic or Postganglionic?

Answer 5

Cardiopulmonary Nerves are considered POSTGANGLIONIC
