Answer: The nervous system regulates and coordinates functions of the
body required to maintain what?
⩥ neurons
glial.
Answer: 2 types of cells in nervous tissue
⩥ neurons.
Answer: electrically excitable cells of the nervous system
⩥ cell body
dendrites
single axon.
Answer: 3 parts of a neuron
⩥ nerve.
,Answer: collection of many axons bundled together outside the brain
and the spinal cord
⩥ cranial nerves (12).
Answer: nerves that originate from the brain (how many?)
⩥ spinal nerves.
Answer: nerves that originate from the spinal cord (how many?)
⩥ plexus.
Answer: bundle of nerves outside the brain and spinal cord
⩥ ganglia.
Answer: clusters of cell bodies formed by neurons outside the brain and
spinal cord
⩥ glial cells.
Answer: supportive cells that serve many functions for the neurons
⩥ 1. maintain homeostasis
2. receive sensory input
3. integrating information
,4.controlling muscles and glands
5. establishing and maintaining mental activity.
Answer: 5 functions of the nervous system
⩥ central nervous system
peripheral nervous system.
Answer: the 2 major divisions of the nervous system
⩥ central nervous system CNS.
Answer: receives information from and sends information to the body;
brain and spinal cord
⩥ Peripheral Nervous System (PNS).
Answer: responsible for detecting stimuli in and around the body and
sending that information to the CN and then communicating messages
from the CNS to the body; nerves, ganglia, and sensory receptors
⩥ sensory
motor.
Answer: 2 divisions of the PNS
⩥ sensory division (afferent).
, Answer: transmits electrical signals from specialized receptors in the
body towards the CNS
⩥ sensory receptors.
Answer: detect stimuli and then send input along nerves, which extend
from the receptor to the brain or spinal cord
⩥ motor division (efferent).
Answer: transmits electrical signals from the CNS to effector organs,
muscles and glands
⩥ somatic
auntonomic.
Answer: 2 branches of the motor division
⩥ somatic nervous system.
Answer: voluntary division of motor system; allows you to decide to
move skeletal muscles
⩥ autonomic nervous system.
Answer: involuntary division of the motor division; regulates activities
without conscious control (contraction of cardiac or smooth muscle, and
secretion of certain glands)
