Review Sheet for Nervous System
Nervous System
 Know there are two control (communicating) systems of your body: endocrine and nervous system
 Be able to list the 3 functions of the nervous system: sensory input, motor output, and integration.
 How do you structurally organize the nervous system? central and peripheral
 How do you functionally organize the peripheral nervous system? Sensory (afferent) and Motor (efferent)
 Be able to draw and label all levels of the nervous system.
 Differentiate between neurons and neuroglia.
 Be able to describe and label the structures of a neuron: dendrite, cell body, nucleus, axon, myelin sheath, nodes of ranvier,
neurotransmitters, and synapse.
 Be able to list and describe the functions of the 3 neuroglia (supporting cells) found in the central nervous system:
astrocytes, microglia, and oligodendrocytes.
 Be able to list and describe the functions of the 2 neuroglia (supporting cells) found in the peripheral nervous system:
satellite cells and schwann cells
 Describe in detail the 2 main functions of a neuron: irritability and conductivity.
 Describe the process of generating an action potential (nerve impulse) and propagating (sending) the signal down the axon.
(There were 10 steps we listed during lecture)
 Be able to define each as it relates to action potentials: polarized (resting) membrane, depolarization, repolarization,
refractory period, and the sodium potassium (Na/K) pump.
