Meninges and Spinal Cord

Nervous System. Functions: Homeostasis Memory Senses Components: Brain, Spinal Cord, Nerves, receptors, ganglia, tracts Can be organized anatomically.

The Nervous System. Functions of the Nervous System 1. Monitors internal and external environment 2. Take in and analyzes information 3. Coordinates voluntary.

 Elaborate communication system that contains more than 100 billion nerve cells in the brain alone  Control the actions of the body  Makes adjustments.
