Learning Objectives

• Outline the various functions of the nervous system
• Describe the properties of the different functional types of neuron
• Outline the properties of the different classes of nerve fibres, relate to their functional roles
• Describe the basic components of a neural reflex arc, using the patellar reflex as an example
• Name the major regions of the brain and describe their primary functions
• Identify the different divisions of the PNS and describe their functional roles
• Describe the basic functional roles of the SNS and PNS and the associated NTs and receptors

Neurons

• functionally, what are the 3 types of neurons?
• what direction do sensory vs motor neurons transmit info?
• where are the cell bodies of sensory vs motor neurons located?
• what is different about the peripheral ending of sensory neurons?
• sensory neurons generate [potentials] from stimuli?
• are interneurons located in the CNS or PNS?
• what is the function of interneurons?
• the more complex the pathway, the [more/less] neurons?

Nerve Fibers & Nerve Reflex Arc
