Section 6.1: Study Guide
Section 6.1 Objectives:
Explain the organization of the nervous
system including the Central nervous
system (CNS), Peripheral Nervous
System (PNS), Autonomic Nervous
System (ANS) and Enteric Nervous
Describe the process for information to
be communicated between the CNS
and PNS. Understand the role of the
Efferent Neurons, Afferent Neurons,
Control Center, Receptors, & Effectors.
Explain the structure of a neuron (soma,
dendrites, axon, myelin, axon terminals)
and the neurons unique features in
lifespan, metabolic rate and mitotic
Describe how neurons are classified by
structure and function. Structural
Classification: Multipolar, Bipolar,
Unipolar. Functional Classification:
Sensory, Motor, Interneurons.
Describe the neuroglia cells of the CNS
and PNS (Astrocyte, Oligodendrocyte,
Ependymal Cells, Microglial Cells,
Satellite cells, & Schwann cells) and
their form, function and relationship
Explain the process of salutatory
conduction and how myelin sheaths
speed up the sending of the action
potentials along the axon Nodes of
ORGANIZATION OF THE NERVOUS
Compare and contrast the structure and function of Neurons and Glial Cells.
Explain the organization of the Nervous System.
Draw a concept map to diagram
the nervous system and add details as you go through this module. Include anatomy
structures involved, functions, unique features, general effects, and relationships.
will be learning more about the Autonomic Nervous System in Module 10 and can
expand your concept map more then.
Be sure to include in your diagram these main
The Nervous System
Central Nervous System (CNS)
Brain & Spinal Cord
Peripheral Nervous System (PNS)
Sensory (or Afferent) Division - Afferent Neurons
Motor (or Efferent) Division
Somatic Nervous System
