Nervous System Flashcards
cerebellum
balance and movement
spinal cord
link between the brain and body
peripheral nervous system
all nerves not part of CNS
meninges
connective tissue that surrounds the CNS
CNS
brain and spinal cord
brain
center of the nervous system
medulla
involuntary movements
stimulus
change in the environment
neuron
a nerve cell
cerebrum
voluntary actions
cell body
metabolic activities
axons
carry impulses away from the cell body
dendrite
off of the cell body, carry impulses from environment/ neurons to the cell body
myelin sheath
insulator, surrounds the axon
response
reaction to a stimulus
interneurons
in the spinal cord and brain, connect sensory neurons to motor neurons
motor neurons
carry impulses from interneurons to effectors (skin)

reflexes
not controlled by the brain
