Responses

nerves

messages

stimuli

signals

3. How do signals from sensory neurons reach motor neurons? (1 point)
Responses

Motor neurons signal for the body to move the signal toward them

Signals move from dendrite to dendrite towards motor neurons

Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons

Signals from sensory neurons do not get sent to motor neurons

Answer 3

2. The correct answer is: stimuli.
