Chapter 11 Bio 114 Review Questions
and Correct Answers
Compare the central and peripheral nervous system ✅The CNS consist of the brain
and spinal cord. It integrates, processes, and coordinates sensory data and motor
commands. The PNS includes all nervous tissue outside the CNS
Which division of the PNS brings information to the CNS? ✅The sensory division of
the PNS brings information to the CNS
Name the effectors of the ANS ✅The effectors are smooth muscle, cardiac muscle,
glands, and adipose tissue
Name the structural components of a typical neuron ✅A cell body, an axon, and
dendrites
Describe a synapse ✅A site where a neuron communicates with another cell. It
involves a presynaptic cell and a postsynaptic cell whose plasma membranes are
separated by a synaptic cleft.
Compare presynaptic and postsynaptic cells ✅A presynaptic cell is generally a neuron.
A postsynaptic can be a neuron or other type of cell, such as skeletal muscle fiber
Why is a CNS neuron not usually replaced after it is injured? ✅Most CNS neurons lack
centrioles, which organize the microtubules of the spindle apparatus during mitosis, so
these cannot divide
Classify neurons based on their structure ✅They are classified as Amazonia, bipolar,
unipolar, or multipolar
Classify neurons based on their functions ✅They are functionally classified as sensory,
interneuron, or motor neurons
Are unipolar neurons in a tissue sample of the PNS more likely to have a sensory or a
motor function? ✅They are most likely to have a sensory function. Motor neurons
which are multipolar have a motor function and are found in the CNS
Name the neuralgia of the CNS ✅Ependymal cells, microglia, astrocytes, and
oligodendrocytes
Which neuralgia appear in increased numbers in a person with a brain infection?
✅Microglia occur
