1. Functions
1.1. The nervous system has millions to billions of sensory receptors that react to stimuli inside and outside the body
1.1.1. These stimuli include
1.1.1.1. Light, sound, taste, feelings, temperature (Our senses)
1.1.1.1.1. Examples of reacting to Stimuli
1.1.2. This helps us stay safe from dangers
1.2. The nervous system sends signals to the muscles
1.3. Controls memory, learning, thoughts and decisions as the central Nervous System includes the Brian
2. Consists of
2.1. Synapse
2.1.1. Function is to
2.1.1.1. Allow information to go from one neuron to another through its gap
2.1.1.1.1. The object that transmits the signal is called a
2.1.2. Synapse are found
2.1.2.1. Where nerve cells connects with other nerve cells. They are also found with nerve cells connecting with glands and muscles
2.2. Neurons (Nerve Cells)
2.2.1. Of which
2.2.1.1. Communicates info throughout the body
2.2.2. Interestingly
2.2.2.1. They make up the basics of the nervous system
3. Is divided into the
3.1. Central Nervous System (CNS)
3.1.1. Includes
3.1.1.1. Brain
3.1.1.1.1. Function
3.1.1.2. Spinal Cord
3.1.1.2.1. Function
3.2. Peripheral Nervous System (PNS)
3.2.1. Function
3.2.1.1. Giving and sending signals to the Central Nervous System
3.2.1.1.1. The signal "messengers" inside the PNS are
