QUESTION
Imagine that a signal is sent from Neuron A in your
spinal cord to your toes that says, "Wiggle your right
big toe!" Trace the pathway of this signal.
ANSWER
Dendrites of Neuron A send a signal
to the axon of Neuron A; its axon
sends a signal to your right big toe;
neurons in your big toe contract and
your big toe wiggles.
Neuron A's axon sends a signal to
muscle cells that control your right
big toe; muscle cells contract, and
your big toe wiggles.
Dendrites of Neuron A send a signal
to the axon of Neuron A; its axon
sends a signal to muscle cells that
control your right big toe; muscle
cells contract, and your big toe
wiggles.
Dendrites of Neuron A send a signal
to Neuron A's axons: they send
signals to muscle cells that control
your right big toe; muscle cells
contract, and your big toe wiggles.
