Nervous System
There are two main parts that make up the Nervous System which is the Peripheral and Central Nervous Systems. These systems respond to internal and external stimuli using the three neurons stimulus, motor and relay neurons.

Specialized Cells
There are three types of specialised cells in the nervous system of an African Elephant. These are Stimulu(sensory), motor and relay neurons.
Sensory Neuron
The sensory neuron takes the information from outside the skin or within to the brain or spinal cord depending on what kind of stimulus.
Relay Neuron
The relay neuron carries information from one part of the central nervous system to the other.
Motor Neuron
The motor neuron sends the message to the muscle
Dendrites
Dendrites are the ends of neurons that receive messages. When the message is passed between dendrite and dendrite this called synapses. Synapses changes the electrical message to a gas to reach the other neuron dendrite. It i

Internal Stimuli
Internal Stimuli is anything that affects inside the body for e.g hormones, temperature and diseases. If the temperature of the body of an elephant heats up past its healthy temperature, the elephant uses its big floppy ears to cool itself by flapping them. The nervous system makes the elephant flap its ears to cool the temperature down or tells the elephant to get some water immediately. Another example of the body responding to Internal Stimuli is when an African Elephant gets hungry. The stimuli is immediately sent up to the brain via the Stimulus Neuron passing along a relay neuron in the brain where the message is delivered.
External Stimuli
External Stimuli is anything that affects the body from the outside for e.g touch and heat. If the elephant was to stand on a very hot surface. the elephant would immediately try to get to get off or on to a cooler surface.

How the Nervous System Works
An example of how the nervous system works is if the elephant is hungry and sees some nice green grass to eat. The rods and cones receive the stimulus noticing the grass to eat. The stimulus neuron takes the stimulus via electrical signals to the spinal cord where it passes through relay neuron. The electrical signal then travels along the motor neuron to the leg muscle to take a step forward and a signal to the trunk to pick up the grass and put it into the elephant's mouth. The mouth then sends the stimulus to the spinal cord pass the relay neuron down the motor neuron to the mouth where it contracts and opens it to put the grass into it.

Central Nervous System
The central nervous system is divided into two parts the brain and the spinal cord. The brain and spinal cord receive messages and contract the necessary muscles.
Peripheral Nervous System
The peripheral nervous system is everything else except the five senses.

Secretion
Secretion is a process when substances are produced and discharged from a cell, gland or organ. When an elephant is feeling hot, it uses its ears to cool itself down. An elephant does not have sweat glands that's why they have to use their ears to cool themselves down. Elephants even role in the mud because it dries and acts for protection from the sun. When an elephant sees a food it wants to eat, its mouth starts to form saliva.
