1. Nervous System Made up of two parts. Central nervous system (CNS) Peripheral nervous system (PNS) The nervous system is essentially the body’s electrical wiring. It is composed of nerves, which are cylindrical bundles of fibers that start at the brain and central cord and branch out to every other part of the body.

3. Peripheral Nervous System

4. Neurons – Delivery System

6. Nervous System Disorders Stroke – loss of brain function due to a disturbance in blood supply Epilepsy – (neurological condition) medical condition where someone had recurring seizures. A seizure is a disruption of the electrical communication between neurons. Multiple Sclerosis (MS) – disease activity damages the myelin, which leads to the breakdown in signal transmission. Brain or spinal cord injuries

7. ENDOCRINE SYSTEM The glands of the endocrine system and the hormones they release influence almost every cell, organ, and function of our bodies. Regulates mood, growth and development, tissue function, and metabolism, as well as sexual function and reproductive processes. In charge of body processes that happen slowly, such as cell growth.

9. ENDROCRINE SYSTEM Pituitary: Often called the "master gland" because it makes hormones that control several other endocrine glands. Hypothalamus: Primary link between the endocrine and nervous systems Thyroid: Located in the front part of the lower neck, is shaped like a bow tie or butterfly. These hormones control the rate at which cells burn fuels from food to produce energy.

10. Adrenal: Two triangular adrenal glands, one on top of each kidney. The outer part, produces hormones called corticosteroids that influence or regulate salt and water balance in the body, the body's response to stress, metabolism, the immune system, and sexual development and function. The inner part, the adrenal medulla, produces catecholamines, such as epinephrine. Pancreas: The pancreas produces (in addition to others) two important hormones, insulin and glucagon. They work together to maintain a steady level of glucose, or sugar, in the blood and to keep the body supplied with fuel to produce and maintain stores of energy. Gonads: sex organs
