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
