The Importance of 5 Senses: Essay Introduction
The knowledge that human beings need to understand the operations of the outside world depends on their modes of sensitivity. As such, the human sensory organs are categorized into vision, hearing, taste, touch and smell. The sense organs are made of specialized cellular configurations that accept specific stimuli. The senses are all critical in the functioning of human receptions to stimuli.
However, the measure of importance of every sense organ differs. In this regard, the sight is the most imperative sensory organs followed by hearing. Touch comes in thereafter since it also plays a critical role in determining the effects of soreness as well as necessitation of therapeutic attention. Further, scent and flavor verify the availability of aroma in food and the sweet, acerbic, astringent as well as saline flavors respectively.
Sight
The extent of the eye sensitivity is extraordinary. On this note, the eyes play fundamental roles in providing individuals with opportunity of viewing all the physical features of the ecosystem. In essence, the functions of the eye surpass the roles of other intelligences. The sight is instrumental in relaying data on the daily life occurrences to the body.
Doubtlessly, many people recognize that in almost every activity carried out by individual be it reading, watching, inscribing correspondences among other countless functions. In addition, the sight plays a vital function in enabling the survival of people in the environment since they are able to see the dangers and run into safety. Further, studies show that many individuals dread amaurosis than other disabilities.
Hearing
Perception of sound is fundamental role in individual aptitudes and amusements such as music and verbal communication. In the modern society, verbal communication is attributed to the intelligence of listening.

Actually, the sense of hearing enables the collection, progression as well as inferring the reverberations continuously with unconscious exertions. On this note, the sense of hearing should not be taken for granted. The growth and quality of an individual’s life originate primarily from the listening capability.
As such, communication is possible through listening to others. In addition, through hearing, an individual is capable of receiving admonitions about hazardous situations and deal with such life challenges,
Touch
The sense of contact is essential in becoming aware of the diverse surfaces as well as temperatures. In essence, the skin through its sensory receptors is significant in the detection of different sensations ranging from soreness to pulsations. Therefore, the sense of touch is vital in circumventing the bodily harms acquired through the daily links with the surroundings.
Smell
The sense of smell is fundamental in creating an environment where animals are capable of tracking their food as well as finding their mates. However, many individuals pay little attention to smell since it has insignificant effects on the operations of individuals.
For instance, there are people who do not love the scent emanating from garbage, pollution and sewage. On the same note, pregnant women are allergic to certain smells that make them sick. On the contrary, there are people who love the scent of flowers and cooking. Therefore, one would leave without the sense of smell.
Taste
Just like other senses, taste plays a significant role in the provision of body nourishment through prompting the salivary glands and the digestive juices. However, doing without the sense of taste is ideal for eliminating obesity since the individuals would lose the appetite for tasting food regularly. Further, lack of the sense of taste is inconsequential since flavor enhancers such as monosodium glutamate have been developed to counterbalance the predicament.
The differences between “Night Terrors” and “Nightmares”
Nightmares and night terrors are frightening happenings that occur at different stages of the sleep cycle exhibiting dissimilar signs. Just to begin with, nightmares are horrid imaginations that occur during the REM phase of sleep. In addition, the occurrence comes about because of stress, illness, eating before going to sleep as well as dozing in uncomfortable pose.
The nightmares are rampant in older children above five years. The nightmares scare the person experiencing the dream. Further, an individual is able to memorize the occurrence of the nightmare since it occurs in the REM sleep that has its longest periods during the early morning hours. In essence, the nightmares are mostly experienced during the dawn hours.
On the contrary, night terrors are horrible occurrences that take place during the non-REM sleep cycle. In other words, the night terrors are common and are experienced during the first hours of slumber. Night terrors are characterized by screaming, sweating and staring in the dead of the night.
In addition, the individuals experiencing the night terrors are unable to remember the particulars of the night fright. In essence, the behaviors emanating from night terrors scare the people who witness the occurrence. Moreover, night terrors are common in children between the ages of two to six years. The causes of night terrors range from sleep deficiency to inconsistent sleep programs.
Types of behaviors occur during stage four NREM
The stage four of non-rapid eye movement is a slow-wave phase of sleep characterized by intense deep sleep. In this stage, the body tissues are repaired and rejuvenated. In addition, the bones and the body muscles as well as resistance systems are strengthened. Further, shorter periods of slumber are experienced by the older generations.
Personality development
Personality development is a continuous process involving the accumulation of an individual’s life pronouncements that lead to the progress of individuality. As such, aspects of genetics as well as environmental influence the way individual personality grows. However, hereditary factors play a greater role concerning the development of individuality.
Just to start with, the initial development of a person begins from the exchanges of sperm and ova that contain the inherent make-ups necessary for life development. In other words, the genes contain the instructions that dictate the advancement of personality. For example, through genetic interactions, the genes compete for dominance and as a result affect development of individual.
Further, traits such as height, shyness, temperament, and love for adventure as well as intellectual advancement are affected by the hereditary characteristics from parents. Worth noting, genetic abnormalities such as the Down syndrome have the effect hearing and heart defects as well as intellectual impairments. Clearly, hereditary attributes greatly manipulates personal development compared to the environmental traits.
The possibility that loud, steady noise-like the hum of the city increasing the chances of developing a mental illness and Physical health problems like a heart attack. Loud noise has adverse effects to an individual’s healthiness as well as welfare. In other words, ensuring an environment that does not pose threats to the well-being of individuals ensures domestic tranquility.
Increased noise pollution has the effect of initiating poor physiologic as well as mental performance in fit individuals. For instance, continuous noise interrupts sleep. Further, noise exposes people to increased vasoconstrictions and changes in the rate of body movements. The incessant noise has negative effects on the sensitive groups such as the elderly leading to mental disorientations.
Further, the loud sounds trigger the hormonal and nervous reactions that initiate increases in the heartbeat rate and blood pressure thereby intensifying the peripheral resistance on the cardiac walls. Such occurrences pose the threats of heart attacks.
Electrical shock and Human Beings
Giving a deadly electrical shock to another individual has severe physiological effects to the individuals. Therefore, performing the electrical astound to another individual would be detrimental. Just to begin with, the body experiences muscular contractions, unconsciousness as well as the fibrillation of the heart. As a result, the contractions of the muscles initiate complexity in inhalation.
In essence, electric shocks are lethal due to the heat that is produced by the flowing current. As a result, the epidermis is unable to provide the required resistance to the current thereby causing burns to the skins. Another danger associated with electrical shocks is the interruptions in the heartbeats thereby posing the threats of cardiac arrests.
Moreover, the electrical shocks are associated with the irregular responses of the heart muscles that ultimately lead to death. The body damages associated with the burns from severe electrical shocks discharge noxious toxins that eventually lead to loss of life.
