1. Sensory information usually travels from the ______________________ nervous system to the
__________________ nervous system.
2. Three common structural features of all neurons are: ___________________________,
____________________________, and ___________________-______________.
3. ____________________ receive information from other neurons, while ___________ receive information
from the cell body and then transmit that information to other neurons.
4. Impulses travel from ______________________ neurons, to ________________________ neurons
after jumping across a ___________________,
5. ___________________ neurotransmitters cause sodium channels to open, which initiates an action
potential, while ___________________ neurotransmitters make it more difficult for the neuron to achieve an
action potential.
6. The neurons that carry information from sensory receptors to the brain and spinal cord are called
___________________neurons, while those that convey information from the central nervous system
to muscles or glands are called ___________________ neurons.
7. Brain and spinal cord tissue composed mainly of neuron cell bodies is referred to as
_____________________ because of its darker pigmentation, while the tissue of the CNS composed
primarily of myelinated axons is referred to as ________________________.
8. The three layers of the _____________________ from deepest to most superficial are the pia mater,
arachnoid, dura mater.
9. The four lobes of the cerebral hemisphere are the _______________, _________________,
________________, and ___________________.
10. The ____________________ surrounds an entire nerve, while the _________________ surrounds
each fasicle of axons, and the ______________________ surrounds each individual axon.
11. A cerebrovascular accident (CVA) can cause a _______________________ , which is a rush of
blood in the brain, or a ________________, which is a blockage of blood to the brain.
