CNS
The two parts of the CNS
Brain and Spinal Cord
Two main nervous systems that make up the PNS
Somatic and Autonomic
Nuclei are clusters of cell bodies found in what nervous system
CNS
Name the four lobes of the brain.
frontal, parietal, temporal, and occipital
These are cells that are specialized for the reception, conduction, and transmission of electrochemical signals
neurons
These carry information to the CNS.
afferent nerves
Carries sensory signals from the CNS to the PNS
efferent nerves
The periphral nervous system contains neural structures called this
ganglia
spinal cord
True or False: The CNS is made up of the most protected organ(s) in the body.
True
Interacts with the external environment
somatic nervous system
Neurotransmitters are passed along this part of the neuron
axon
Part of the midbrain that controls movement/motor responses
basil ganglia
this word means "sea horse" and plays a major role in memory
hippocampus
Three protective membranes
Sympathetic changes are indicative of what
internal arousal
Another type of cell (other than neurons) in the nervous sytem
glial
Regulates emotions
amygdala
These are stored in synaptic vesicles and are released from neurons
neurotransmitters
Pia mater
parasympathetic changes are indicative of
psychological relaxation
This glia (glia) cell responds to injury or disease by multiplying, engulfing cellular debris or even entire cells and triggers inflammatory responses
microglia
This "system" controls our fight, flight, feeding, and sexual behavior
limbic system
This condition is caused when the flow of cerebrospinal fluid is blocked by a tumor near one of the narrow channels that link the ventricles, causing the walls of the ventricles to expand
hydrocephalus
