B. brain, sensory neuron, myelin

C. interneuron, spinal cord, autonomic

D. somatic, brain, spinal cord

2. Which of the following is not a function of the human nervous system?

A. regulating heartbeat

B. listening to music

C. moving oxygen from air into the blood

D. signaling the diaphragm to contract

3. Which of the following correctly describes how nerve impulses move throughout the body?

A. electrical trans

Q1. The answer is A. motor neuron, interneuron, sensory neuron

Sensory neuron receives signals from the environment and sends it to the central nervous system. Interneuron is the part of the central nervous system, it is found in the spinal cord where is involved in reflex action. In those reflex actions, the signal from sensory neuron is sent to interneuron and it sends it back to motor neuron which sends the signal to the effectors. In reflex actions signal is not sent to the brain because immediate reaction is necessary.

Q2. The answer is C. moving oxygen from air into the blood

The central nervous system is involved in regulating heartbeat, listening to music, signaling the diaphragm to contract. However, it is not involved in moving oxygen from air into the blood. Circulatory and respiratory systems are responsible for moving oxygen from air into the blood.
