Students will be able to
- recall that nerve cells are referred to as neurons and are specialized to transmit electrical impulses,
- describe the structure of a neuron as being the cell body (including the nucleus and neuroplasm), dendrites, axon, nodes of Ranvier, and the myelin sheath (including the neurolemma),
- describe the functions of the parts of a neuron,
- recall that the flow of a nerve impulse through a neuron travels from dendrites cell body axon axon terminals,
- describe and compare the functions of sensory, motor, and relay (connector) neurons,
- describe the structure of a nerve as bundles of neurons surrounded by connective tissue (epineurium),
- state the functions of the neuroglia as providing support and protection, supplying nutrients, and repairing damaged neurons.
