The+Nervous+System


 * The Nervous System** is a system of specialized cells that t__ransmit signals from one cell to an other or from one body part to an other. Its goal is to maintain homeostasis by propagating impulses.__

The __major organs__ of the Nervous System are the **brain** and the **spinal cords.**

__System information__: A **neuron** is a specialized impulse, conducting cells that is the functional unit of the Nervous System.

A neuron __works by sending messages through out the body electrochemically.__

The __divisions__ of the Nervous System are; the **Central Nervous System ( the Brain)** and the **Peripheral System ( These cells carry information to sensory nervous cells.)**

The __sub divisions__ of the Nervous System are; **Sympathetic Division (Preparing the body to respond and cope with threats.)** and the **Parasympathetic Division (deals with he digestion, urinary, and defecation, state of rest.)**

__INTERRELATIONSHIPS__ of the Nervous System: **Integumentary** and **Skeletal Systems**. In the **__Integumentary System__** the __skin protects nerves__, the Nervous System has __neurons inside skin to help protect itself.__ In the **__Skeletal System__** the __bones made of your skull help protect your brain__, and your __spine protects your spinal cord.__
