THE MAIN ATTRACTIONS:

Brain Maze: Can you make it through the brain maze? The brain maze is a life sized maze which is created by the folds in the brain. This maze is approximately three miles long.

Spinal Drop: On this ride, you will drop from the first vertabrae all the way down to the coccyx within seconds. This is forty stories high, and the carts will be travelling eighty miles per hour.

Rafting: You can go white water rafting in the folds of the brain. This attraction is located on the opposite side of the brain which the Brain maze is located on.

HOT SPOTS:

The two most popular places to go in the nervous system are the spinal cord and the brain.

INFORMATION ON THE NERVOUS SYSTEM:

1. The basic unit of structure in the nervous system is the neuron. Neurons are cells that conduct imupulses throughout the nervous system. The function of the nervous system is to control the rest of the human body.

2. Diagram of a neuron, the neuron operates in five steps which are described below:

Reception:Receptors sense touch or other stimuli.
Transmission:Sensory neurons transmit the message.
Data interpretation:Information is sorted and interpreted, and a response is determined.
Transmission 2:Motor neurons transmit a response message to the area where the message came from.
Response:When the area of the body receives this message, it responds.

3. The brain is a highly organized organ that contains about 35 billion neurons, and has a mass of 1.4 kilograms. The brain is the origin where impusles originate, the spinal cord provides a link so that these impulses can reach other parts of the human body. The brain is divided into four lobes, plus the brainstem and cerebellum. The frontal lobe is located in the front of the brain, the parietal lobe is located right behind the frontal lobe. The occipital lobe is located behind the parietal lobe and goes to the end of the head, and finally the temporal lobe is located underneath the first three lobes. Just beneath the temporal lobe is the cerebellum, and in front of the cerebellum is the brain stem which runs all the way down to the spinal cord. Here is a list of what the brain controls, starting at the right side to the left in order. The abdomen is the first part of the human body that the brain controls, this is followed by the pharynx, tongue, teeth, lips, face, nose, eye, thumb, fingers, hand, arm, head, neck, trunk, which is located close to the center of the brain at the top of the head. Just below the trunk, the brain controls the hip, below that the brain controls the leg, below that the brain controls the foot, and below that the brain controls the reproductive organs. The left side of the brain controls the following parts of the body in order, starting at the top middle part of the brain the trunk, the shoulder, then the shoulder is followed by the arm, wrist, hand, fingers, thumb, brow, eye, face, lips, jaw, tongue, and finally, swallowing.

4. The peripheral nervous system transmits impulses to and from the body and the central nervous system. The peripheral nervous system is composed of the somatic and autonomic nervous systems.

5. A nerve impulse causes a movement of ions across the cell membrane of a neuron, like a ripple passing along the surface of a lake. The cell membrane of a neuron has thousands of tiny molecules which are known as gates. These gates are generally closed, but they allow either sodium or potasium ions to pass through. However, the sodium gates open at the leading edge of an impulse, which allows positively charged Na+ ions to flow inside the cell membrane. Because of this, the inside of the membrane temporarily becomes more positively charged that the outside. When this happens the membrane is said to be depolarized. As this impulse passes, the potassium gates open, which allow positively charged k+ ions to flow out. When this happens the membrane is now said to be repolarized, which means that, once again the inside of the cell membrane is negativly charged, while on the outside, it is positively charged. The depolarization and repolarization of a membrane produce an action potential. The nerve impulse can be defined as an action potential traveling along the membrane.

6. A sensory neuron is stimulated by sensory receptors which relays the signal to an interneuron within the spinal cord. The signal is then sent to a motor neuron which then stimulates an effector. This is illustrated in this diagram.

WARNING:

WHEN YOU ARE WALKING AROUND IN THE BRAIN, WATCH YOUR STEP, BECAUSE THE BRAIN IS VERY SLIPPERY.

IMPORTS:

The nervous system imports a lot of oxygen from the lungs. The nervous system also imports a lot of blood from the heart.

EXPORTS:
The nervous system exports lots of neurons, and signals, which control the human body.
