Impulses only travel in one direction in a neuron. What direction do they travel?

Back

From the dendrite to the axon terminals

What way do impulses travel across synapses?

Back

From axon terminal to dendrite

What do sensory neurons do?

Back

Transmit impulses from sense receptors to the brain and spinal cord

What do motor neurons do?

Stimulus = hot pan

Receptor = skin

Effector = muscles in arm and hand

Response = move hand away
