In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. [ 1 ]
It was the title of a marching song sung by women during WWII. The chorus goes "If you're nervous in the service, And you don't know what to do / Have a baby, get out of the Navy." Later, it was generalized to just meaning "nervous", so that the word "service" is now just a bit of rhyming nonsense, like the "Ruth" in "that's the truth, Ruth".

Neuropharmacology is a very broad region of science that encompasses many aspects of the nervous system from single neuron manipulation to entire areas of the brain, spinal cord, and peripheral nerves. To better understand the basis behind drug development, one must first understand how neurons communicate with one another. [citation needed]
The vertebrate nervous system is divided into the central and peripheral nervous systems. The central nervous system (CNS) consists of the brain, retina, and spinal cord, while the peripheral nervous system (PNS) is made up of all the nerves and ganglia (packets of peripheral neurons) outside of the CNS that connect it to the rest of the body ...
