Name two cell types in neural tissue. - Answers-neurons
and glia
What are neurons? - Answers-"rapid communicators,"
excitable cells that transmit electrical signals
What are glia cells? - Answers-"caregivers," cells that
provide support for neurons
Name two groups of nervous system organs. - Answers-
Central Nervous System (CNS) and Peripheral Nervous
System (PNS)
List the general functions of the nervous system. -
Answers-sensory function:
-nervous system receives information
,2|Page
-sensory receptors gather information by detecting
changes
-information is carried to the CNS
integrative function:
-nervous system coordinates sensory information to create
new sensations, memory, thoughts
-nervous system makes decisions on body's response to
sensory information
motor function:
-decisions are acted upon
-impulses are carried to effectors (muscles or glands)
-divisions of motor portion of PNS
-somatic nervous system- transmits voluntary instructions
to skeletal muscles
-autonomic nervous system- transmits involuntary
instructions from the CNS to smooth muscles, cardiac
muscle, and glands
Describe a neuron. - Answers--dendrites: receive signals
,3|Page
-cell body: manufactures cell components, integrates
signals
-axon: conducts impulses
-synaptic knob: site of contact with target cell
-myelin sheath: formed by neuroglia cells to insulate
axons; interrupted in peripheral neurons by nodes
Explain how an axon in the PNS becomes myelinated. -
Answers-myelinated axons in the PNS have a series of
Schwann cells lined up along the axon, each having a
wrapped coating of myelin insulating the axon
Describe the types of neurons based on structural
characteristics. - Answers-multipolar neurons:
-99% of neurons
-many processes
-most neurons of CNS
bipolar neurons:
-two processes
-eyes, ears, nose
, 4|Page
unipolar neurons
-one process
-cell bodies are in ganglia
-sensory
Indicate the function of sensory neurons. - Answers--
afferent neurons
-carry impulse to CNS
-most are unipolar
-some are bipolar
Indicate the function of interneurons. - Answers--
association neurons
-link neurons
-multipolar
-located in CNS
Indicate the function of motor neurons. - Answers--
multipolar, efferent
-carry impulses away from CNS
-carry impulses to effectors
