Learning Objectives

IX. Learning Objectives: Peripheral nervous system

 

  1. You should be able to define the following terms: antagonism, dual innervation, effectors, pre- and postganglionic, nicotinic type 1 receptor, nicotinic type 2 receptor, muscarinic receptor, cholinergic, adrenergic, acetylcholine, norepinephrine, alpha 1 adrenergic receptor, alpha 2 adrenergic receptor, beta 1 adrenergic receptor, beta 2 adrenergic receptor, divergence,
  2. You should be able to discuss the characteristics of the somatic nervous system.
  3. You should be able to compare and contrast the somatic and autonomic nervous systems,
  4. You should be able to diagram a 1- neuron and 2- neuron system.
  5. You should be able to compare and contrast the sympathetic and parasympathetic nervous systems.
  6. You should be able to identify the neurotransmitters associated with the different divisions of the peripheral nervous systems and where they are released.
  7. You should be able to identify the receptors for the different divisions of the peripheral nervous system.
  8. You should be able to discuss the effects of sympathetic input on the various systems of the body.
  9. You should be able to discuss the effects of the parasympathetic input on the various body systems.

At the end of this section, you should understand the differences between the autonomic and somatic nervous systems. You should also be able to explain how the two divisions of the autonomic nervous system differ from one another, especially with regard to the effects they have on their effectors, the neurotransmitters they release and the receptors to which these neurotransmitters bind. Understanding these concepts is the basis for understanding how the systems of the body are controlled, how pathological conditions develop and how drugs affect human physiology.
