a neuron that can receive signals from neurons and transmit impulses to neurons; they are mostly located in your brain and spinal cord

Question 12

motor neuron

Answer 12

neuron that receives signals from the brain and spinal cord and sends them to effectors such as muscles or glands

Question 13

nerve

Answer 13

a big group of axons bundled together

Question 14

grey matter

Answer 14

part inside the spinal cord which contains neurons

Question 15

white matter

Answer 15

part inside the spinal cord which contains the axons of the motor neurons and sensory neurons

Question 16

reflex

Answer 16

a rapid, automatic response to a stimulus
