How do signals from sensory neurons reach motor neurons?(1 point)
Responses
Signals move from dendrite to dendrite towards motor neurons
Signals move from dendrite to dendrite towards motor neurons
Through interneurons in the brain and spinal cord that connect sensory neurons and 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
Signals from sensory neurons do not get sent to motor neurons
Motor neurons signal for the body to move the signal toward them
Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons, signals from sensory neurons reach motor neurons.
