The nervous system functions as the control center of the body. It collects and processes information to control and coordinate all parts and processes. The brain is the largest organ in the nervous system, made up of billions of nerve cells. It has three main parts: the cerebrum, cerebellum, and medulla oblongata. The spinal cord is made up of fibers that carry information between the brain and body. It serves as a reflex highway. Peripheral nerves connect to neurons throughout the body. Neurons are the basic units that collect and carry nerve impulses. The document provides information about the main parts and functions of the nervous system.

2. FUNCTIONS OF NERVOUS SYSTEM
 The Nervous system serve as the control center of the
entire life.
 It controls, monitors and coordinates all body parts and
processes.
 It collects and process the information.

5. BRAIN
 the Brain is the largest organ in the
nervous system.
 The Brain is also made up of billions of
nerve cells
Three Major Parts of the Brain
1. Cerebrum 3. Medulla Oblongata
2. Cerebellum

6. SPINAL CORD
the spinal cord is made up of fibers that
carry information to and from the brain.
The spinal cord is the “information
highway” of the nervous system.
The main function of spinal cord is to
serve as a reflex.

7. PERIPHERAL NERVOUS SYSTEM

8. NERVE CELL OR NEURONS
the nerve cells or neurons are
the basic units of the nervous
system.
Their main function is to collect
and carry nerve impulse.
