Experience can be defined as something or nature of events that someone has undergone.

It is what happens to us all the times as long as long as long as we live. Experience is not only what happens to a man, but it is also what a man does with what happens to him or her. Experience plays a major role in visual perception and object recognition. Basically, it's important to have some experience of something when looking at it for you to recognize it.But this is not the case always, sometimes you can look at something for the first time and you just take it for known since you had previous experience with some objects that looks the same, which might be similar in all aspects to the one that you are seeing and recognizing at the moment. For example, when you see a book that you read everyday you will be sure it is your book, you recognize it as being yours because you bought it, you read thus you knew it before.

You recognize the book and you make it part of your visual perception, you just see it and recognize what it is because you have done that before.Just imagine you have seen a new book that you have never read or seen before, you will somehow recognize it because it has similar features to your book. It has the same structure, you can read it, you hold it the same way, but it is very different from your book, thus you identify the two objects as different objects in your visual perception, which allows you to recognize them and tell which one is which the next time you see them since you already had the same experience before. Senses can be defined as the physiological methods of perception.An exteroceptive sense is a faculty by which outside stimuli of sight, touch, smell, taste and hearing are perceived.

The senses and their classification, operation and theory are major topics that are being studied by various fields like cognitive, neuroscience, cognitive science and philosophy of perception. Sensation is a mind condition which results from some inherent feelings or spiritual. They are physical affection or purely spiritual, agreeable or disagreeable feelings that are occasioned by objects that.The nervous system has got a specific sensory organ or system that is dedicated to each and every sense. For example if somebody perceives that some people are out to get them, it is possible that they will start seeing people following them, or they think that there some people who are jumping out from the bushes and spying on them.

The paranoia is known to heighten all the five common senses. This is also true in conditions of extreme excitement, which releases endorphines which is responsible for stimulating the nervous system and all the five common sense.Some studies have been done through hypnosis where someone through suggestion is able to taste whatever item that is mentioned or not feel a flame. This is one way in which perception is shown to create one's reality and how it can easily alter one's five common senses.

Scott (1982) explains, At the sites of sensation of these different modalities they are turned into electrical signals that the brain understands, they communicate via action potentials across neurons in the nervous system and are then brought to the brain for processing.A sensory receptor is an organ that has nerve endings that respond to stimulation and transmits a neural signal to the brain and are found in parts of the body like mouth, nose and eyes. They are responsible for the sense of touch, smell and taste. Near sense is the sense that can only detect items that are in the environment when they come into contact with the organism. The nerve cell is a specialized cell within the nervous system that transfers messages from one part of the body or from the brain to another part. Olfactory neurons are responsible of the smell sense.

They are located in the nose and are stimulated by odor compounds in two ways which are, orthonasal stimulation which is caused by odor compounds traveling through the external nares which are also called nostrils to the olfactory bulb. The other way is called Retro nasal where by the odor compounds travels through the internal nares which are located in the mouth. Odor compounds are hydrophobic, volatile compounds that are larger than the taste compounds, they evaporate readily and they dissolve in oil and not in water. Papilla is a small, round or cone shaped bump that is found in the mouth on the surface of the tongue.There are many types of papilla but it is only one that is responsible for the sense of taste which is called Fungi form.

Fungi form has some taste buds that contains papillae and are located on the front two-third of the tongue. They can be seen as red bumps when under magnification and they look like fungi or mushrooms. Sensory system is divided into two, on one side we have perception which comprises of raw, naked immediacy of the receptor organs for taste, touch, smell, hearing and sight. Perception doors at the olfactory, somato-sensory, gustative, hearing and visual systems of the Central nervous system.

On the other hand, the main end results of an array of central neural systems which is committed to process the coded form of the impulse perceived by receptor, for example the secondary and tertiary sensory areas, the angular gyrus in the inferior parietal lobe the limbic system and the ascending reticular activation system in the brainstrem for the general arousal level of the Central nervous system. Mental state are based on sensation or are based on non-sensation. Sensation has a body location and it possess raw feels that are defined by the five common sense.The nervous system cell is one of the complex and important cell in the body of a human being that is responsible for sensory input, motor output and integration. The systems has two types of cell which are neurons and support cells.

Neurons makes the majority of nervous cells and they are responsible of transmitting messages. They differ in size depending on where they are found in the body and they includes, Dendrite, Cell body and Axon. The supporting cells are nine times numerous than the neurons, they assist, insulate and segregate the neurons.Each supporting cell has a specific function and location. The majority of the central nervous system support cells are known as glial cells sound that wrap around the nerves of the space to protect them. The nervous system is divided into two separate systems which are peripheral nervous system and the central nervous system.

the central nervous system is the central of the nervous that operates with only two organs which are, the spinal cord and the brain. Scott (1982) states that, the spinal cord serves as an integration center or interpretation center of sensory and motor neurons.The sensory neuron informs the body of the environment while the motor neurons interprets the information and responds to the environment. The brain is divided into three parts which are, mid brain, hind brain and the fore brain. The peripheral nervous system is divided into two groups which are the sensory and the motor. the sensory neurons also called the afferent-sound neurons which provides information from the environment to the body while the motor neurons also known as efferent sound neurons are used by the body to respond to the environment.
