Describe nervous system with its structure and functions.

1.	Describe nervous system with its structure and functions.
Answer» Function: The nervous system has three general functions: a sensory function, an interpretative function and a motor function. 1. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to central nervous system (CNS). 2. Sensory information brought to the CNS is processed and interpreted. 3. Motor nerves convey information from the CNS to the muscles and the glands of the body. Structure: The nervous system is divided into two parts: 1. The central nervous system consisting of the brain and spinal cord. These structures are protected by bone (Skull and Vertebral Column) and protected from injury by the cerebrospinal fluid (CSF) which acts as cushion or shock absorber 2. The peripheral system, which connects the central nervous system to the rest of the body.
