What are the 3 main organs of the nervous system?
The Human Nervous System: The major organs and nerves of the human nervous system. The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS.
What are 5 organs in the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body….Nerves
- Afferent, Efferent, and Mixed Nerves.
- Cranial Nerves.
- Spinal Nerves.
What are the organs and functions of the nervous system?
The Brain and Spinal Cord Are the Central Nervous System. Nerves and Sensory Organs Make Up the Peripheral Nervous System. Together, the central nervous system (CNS) and the peripheral nervous systems (PNS) transmit and process sensory information and coordinate bodily functions.
What is the main organ that controls the nervous system?
The brain
The brain is like a computer that controls the body’s functions, and the nervous system is like a network that relays messages to parts of the body.

What are the units of the nervous system?
The basic unit of the nervous system is the nerve cell (neuron). Nerve cells consist of a large cell body and two types of nerve fibers: Axon: One elongated extension for sending messages as electrical impulses. Dendrites : Usually many branches for receiving impulses.
What are the different types of nervous systems?
There are four types of nerves- afferent nerves, sensory, inter neurons and motor. There are two main types of nervous systems—the Peripheral Nervous System (PNS) and central nervous system (CNS).
What are the sensory organs of the nervous system?
The sense organs — eyes, ears, tongue, skin, and nose — help to protect the body. The human sense organs contain receptors that relay information through sensory neurons to the appropriate places within the nervous system.
