The nervous system is made up of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). Here's a breakdown of the organs found in each:

Central Nervous System (CNS):

* Brain: The control center of the body, responsible for thoughts, emotions, memory, and controlling most bodily functions.

* Spinal Cord: A long, thin bundle of nerves that extends from the brain down the back. It carries messages between the brain and the rest of the body.

Peripheral Nervous System (PNS):

* Nerves: Bundles of fibers that carry messages between the CNS and the rest of the body. These can be further divided into:

* Cranial Nerves: 12 pairs of nerves that originate from the brain and control sensory functions (sight, hearing, taste, smell), motor functions (muscle movement), and autonomic functions (heart rate, digestion).

* Spinal Nerves: 31 pairs of nerves that originate from the spinal cord and control sensory and motor functions in the body.

* Ganglia: Collections of nerve cell bodies located outside the CNS, which act as relay stations for nerve signals.

Important Note: While these are the main organs, the nervous system also includes a variety of specialized cells, such as neurons, glial cells, and neurotransmitters.
