Which Structure Would Allow You to Move Your Hand Away

Question

Which structure would allow you to move your hand away from a hot burner after touching it?
A) sensory neuron
B) interneuron
C) motor neuron
D) glial cell

Accepted Answer

A motor neuron is a type of neuron that sends signals from the central nervous system to the muscles or glands, causing them to contract or secrete, respectively. In this scenario, when the hand touches a hot burner, a sensory neuron sends a signal to the spinal cord, where it is processed by interneurons. The interneurons then send a signal to the motor neuron, which causes the muscles in the hand to contract and move the hand away from the hot burner.
