Detailed explanation-1: -The nervous system allows an organism to respond quickly to changes in the internal or external environment. The responses to the stimuli are short-lasting.
Detailed explanation-2: -The central nervous system (CNS) is designed to respond to the environment and is peculiarly vulnerable to many of the influences found in the environment. Utilizing an anatomical classification (cortex, cerebellum, peripheral nerves) major toxins and stresses are reviewed with selections from recent references.
Detailed explanation-3: -The nervous system enables the body to respond and adapt to changes that occur both inside and outside of the body. Neurons contain several axons to carry messages to the cell body. Nerves are a combination of many nerve fibers located in the brain and spinal cord.
Detailed explanation-4: -Based on the sensory input and integration, the nervous system responds by sending signals to muscles, causing them to contract, or to glands, causing them to produce secretions. Muscles and glands are called effectors because they cause an effect in response to directions from the nervous system.
Detailed explanation-5: -The nervous system plays a role in nearly every aspect of our health and well-being. It guides everyday activities such as waking up; automatic activities such as breathing; and complex processes such as thinking, reading, remembering, and feeling emotions. The nervous system controls: Brain growth and development.
