nervous coordination and neurons Flashcards
what are the hemicals in the nervous system known as
neurotransmitters
give four differences between the hormonal system and nervous system
hormonal is transported by blood where as nervous is transported by neurons
hormonal transmission is usually slow where as nervous transmission is rapid
hormonal response is slow nervous response is rapid
hormonal response is long lasting nervous response is short
what are neurons
specalized cells
what is a motor neuron made up of
cell body
what does the cell body contain
nucleus
RER
what comes of the cell body
dendrons
what do dendrons branch into
dendrites
what else is attached to the cell body
axon
what does the axon do
carriers nerve impulses away from the cell body
what is at the end of the axon
axon terminal
what covers the axon
schwann cells
what also covers the axon and schwann cells
myelin sheath
what are the gaps in the mylein sheath called
nodes of raniver
what is the function of the dendrites
to carry nerve impulses towards the cell body
what is the function of the schwann cells
provide electrical insulation and carry out phagocytosis
