ANAT100 - Module 5 Exam Questions With
Correct Answers A+
Name the functions of the nervous system - Answer✔sensory input, integration, motor output
Describe sensory input in the nervous system - Answer✔- gathers sensory information about
external and internal environments
- input is detected by sensory nerves and travels through the body to communicate with other
cells
Describe integration in the nervous system - Answer✔- puts together all incoming sensory
signals to create a complete picture of the environment
- incorporates multiple simultaneous signals
- occurs in brain or spinal cord
Describe motor output of the nervous system - Answer✔- produces appropriate responses to
integrated sensory input by sending motor output so glad through motor nerves
- communicates signals from brain and spinal cord to body muscles (causes them to contract or
relax)
What are the 2 principal subdivisions of the nervous system? - Answer✔1. CNS (brain and
spinal cord)
2. PNS (cranial nerves, spinal nerves, ANS, special sense organs)
Describe the organization of the nervous system - Answer✔1. CNS & PNS
2. PNS divided into motor (efferent) and sensory (afferent) systems
3. Motor (efferent) system divided into autonomic and somatic nervous systems
4. Autonomic system divided into sympathetic and parasympathetic systems
What are the 2 principal cell types in the nervous system? - Answer✔1. Neurons
2. Supporting cells
Describe neurons - Answer✔- nerve cells

- excitable
- can generate and transmit electrical signals to other neurons
Describe the structure of a neuron - Answer✔- cell body
- cytoplasmic processes (dendrites and axon)
Describe the direction of a nerve impulse - Answer✔- unidirectional
- signals travel from dendrites to the cell body through the axon to reach dendrites of adjacent
nerves or target organs
How are neurons classified? - Answer✔by the number of cellular processes
What are the 3 classifications of neurons? - Answer✔pseudounipolar (unipolar), bipolar,
multipolar
Describe pseudounipolar neurons - Answer✔- 1 cellular process (splits into a dendrite and an
axon)
give an example of a unipolar neuron - Answer✔general sensory nerves
Describe a bipolar neuron - Answer✔- 1 axon and 1 dendrite that extend directly from cell body
Give an example of a bipolar neuron - Answer✔special sense organs (sight, hearing)
Describe a multipolar neuron - Answer✔- multiple dendrites and 1 axon
- sums to 3+ cellular processes
What is the most common classification of neuron? - Answer✔multipolar
Give an example of a multipolar neuron - Answer✔motor neurons
Describe supporting cells in the nervous system - Answer✔- neuroglia or glia
- protect and support neurons
- aid in sending signals to improve communication
- do NOT generate or transmit nerve impulses
What are the 4 types of supporting cells in the nervous system? - Answer✔1. astrocytes
2. microglia
3. ependymal cells
4. ogliodendrocytes
Which are the most abundant glial cells in the CNS? - Answer✔astrocytes
