Describe the anatomy of the sympathetic division

Expert Solution
Step 1

The nervous system in the human body is responsible for controlling all the body parts through transmission of nerve impulses. In humans, the nervous system contains two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The human central nervous system is mainly composed of the brain and the spinal cord. It regulates all the sensory and the motor working aspects of the body parts. The peripheral nervous system contains nerves which are responsible for connection of CNS to every other body part.

The Autonomic Nervous System (ANS) is a part of PNS that controls smooth muscles and glands. Therefore, ANS directly influences the functioning of most of the internal organs in the body and regulates the body's unconscious actions. The ANS is further divided into two divisions: sympathetic nervous system and parasympathetic nervous system.
