Amphetamines, which are commonly prescribed to treat ADHD, can lead to elevated heart rates and increased arousal. Some psychoactive drugs can also affect the functions of the autonomic nervous system. Psychotherapy that reduces stress, then, can affect the autonomic nervous system and may improve overall health. Chronic stress can lead to elevated heart rates, increased blood pressure, dilated pupils, and other symptoms of increased arousal. While the autonomic nervous system is only partially under conscious control, psychological states can affect the system. However, these two systems also work together in many capacities for example, both play a role in sexual orgasm. The parasympathetic nervous system – The parasympathetic nervous system acts as a counter to this function, by slowing down the body after a period of activity. Somatic nervous system, the A major branch of our peripheral nervous system, the somatic nervous system consists of two types of nerves.The first sensory nerves transmit information about our outside world to our CNS.Sensory nerves allow us to experience pain, pressure and changes in temperature.The sympathetic nervous system – The sympathetic nervous system often acts as a mobilizing agent that prepares the body for action by engaging in functions such as elevating heart rate and increasing respiration.The autonomic nervous system can be further broken down into two sub-systems: The autonomic nervous system is regulated in an area called the medulla oblongata which is a part of the lower brainstem. For example, people cannot choose to alter their heart rate or blood pressure. Some portions of the system, however, are not under conscious control. When people do not actively choose to control these functions, however, the autonomic nervous system takes over and controls them. For example, people can choose to hold their breath or swallow rapidly. Although primarily unconscious, many aspects of the autonomic nervous system can come under conscious control. It controls vital body functions such as heart rate, swallowing, breathing, digestion, and arousal. The autonomic nervous system is included in the peripheral system and is largely unconscious.
