CENTRAL NERVOUS SYSTEM: The CNS consists of the brain and the spinal cord which have an intimate dual connection through the nerves with the rest of the body and particularly with the genital organs. The brain receives sensory signals and transmits messages to the muscles, for appropriate action. The sensory signals initially play a very important role in sexual arousal.

AUTONOMIC NERVOUS SYSTEM: The ANS is outside the control of the will, and regulates your internal environment. It is also responsible for producing erection of the penis and ejaculation. It functions quietly day after day, whether you are awake or asleep. Normally you are not conscious of your heart beats or the digestion going on in your alimentary tract. The ANS maintains law and order in your body through its own intelligence agencies. Every organ is under its surveillance. The moment it misbehaves (for example, indigestion or a heart attack), it is promptly reported to the boss—the central nervous system, for the necessary corrective action. For instance, when an individual suffers from a heart attack, the pain in the chest alerts the CNS to take appropriate action—take a sedative or lie in bed or consult a doctor.

The ANS consists of two components, the sympathetic and the parasympathetic.
