Senses essay

Critical thinking Each healthy human being is born with five senses to include sight, smell, hearing, touch, and taste. The relationship between these components allows living beings to function daily by using sensory perception. The Merriam-Webster dictionary, defines sensory as conveying nerve impulses from one of the sense organs, eyes, ears, mouth, hands, or nose, to the nerve center where information is received regarding the surroundings of a person Merriam-Webster. According to the Merriam-Webster dictionary perception is defined as the way an individual notices and understands something using one of the five senses Merriam-Webster.

They are many different areas in the field if neuroscience. Neuroscience deals with the five senses, anything connected to the nervous system, the brain, anything that sends information to and from the brain, etc. Many of these things go from simple ideas and concepts to the complex coding of the brain, and everything in between.

One of the areas of study that can go from being simple to complex easily is the study of the five senses, sight, hearing, taste, smell, and touch. These five senses may seem simple to describe and easy to define, but they are some of the most complex functions in the human body.

Some might say, "How does this pertain to neuroscience? The answer to that is that each of these five senses Senses essay neurons, and these neurons have to be dealt with.

The bodily function Senses essay deals with these neurons is the nervous system. The first of these senses is taste, or gustation. Taste, as everyone knows, is what happens when some thing is placed on the tongue.

A more technical definition is that it is the direct detection of chemical composition, usually through contact with the tongue. The tongue is the muscle that has different nerves on it that relay information to the brain, via the nervous system.

This information is put back together and depending on your likes and dislikes, you either spit the food out or keep eating. Brandt 4 The tongue is covered with chemoreceptor cells that detect the chemical composition of foods or drink, or anything put into the mouth.

Also in the tongue are taste buds. There are about 10, taste buds on the tongue. These taste buds are linked to the brain by nerve fibers, and when food is detected by the taste buds, they relay signals to the brain.

In technical terms the sense of taste is picked up by the taste buds and conveyed via three of the twelve cranial nerves. First is the facial nerve that carries the taste signals from the two-thirds of the tongue that is showing, the other third is carried by the glossopharyngeal nerve, and the vagus nerve carries some from the back of the mouth.

This information is then processed by the gustatory system, the taste sub-system of the nervous system. With this information, the brain then decides if it likes what it is eating or not.

On the tongue are also the four well-known receptors that determine and detect sweet, salt, sour, and bitter. The bitter receptors are on the back of the tongue.

While the receptors that detect saltiness are on the very tip of the tongue. Sweetness is detected on most of the front half of the tongue, while the sour receptors are on the back half on the sides.

The sense that works similarly to taste is the sense of smell. Smell, or olfaction, is another chemical sense. Unlike taste, there are hundreds of olfactory receptors, each that bind to particular molecular feature.

So where taste used taste buds to detect a chemical composition, these receptors will detect a distinct molecular feature of an odor. Just like taste, smell has its own sub-system of the Brandt 5 nervous system, this is called olfactory system.

Unlike all the other senses the, the olfactory receptors will die and regenerate on a regular basis. The organ that centralizes the olfaction system is the nose.

The nose on vertebrates normally houses the nostrils, which admit and expel air for respiration. In most mammals, the nose also houses the nose hairs, which catch airborne particles and prevent them from getting to the lungs.

In most mammals the nose is the primary organ for smelling.

As the air flows through the nose it runs over structures called turbinates in the nasal cavity. These structures cause the air to slow and it is directed toward the olfactory epithelium.

Once at the surface of the olfactory epithelium, odor molecules carried by the air come in contact with the olfactory receptors. The olfactory receptors turn the features of the odor molecule into electrical impulses that are then sent to the brain to manage.

The olfactory system has many functions that it must accomplish. These functions include creating a representation of an odor, determine the strength of an odor, identify the odor across different concentrations, distinguish new odors from background environmental odors, and pair an odor with a memory of what the odor represents.

And to do these functions it utilizes more than itself as the primary system. It uses many different parts of the brain to encode the odorants and their particular memories. These odor memories are easily stored in long term memory and have strong ties to emotional memories.Essay on Sense N Sense Final.
