The Five Senses When humans were evolving a key to their development was The Five Main Senses that we knew today as Hearing, Sight, Smell, Taste and Touch. The loss of any of these could have affected the survival of our Ancestors, but in modern times, the partial to total loss of any of The Five Main Senses does not carry the same danger. However today, losing one of our main senses can be uncomfortable and isolating, but it does not mean that our useful lives are over. The loss of each of the senses has a different consequence, methods to cope with that loss, and feelings attached to that loss, both by the person affected and the rest of society. Humans have a multitude of senses, but The Five Main Senses are: Hearing (Audioception) …show more content…
This fluid-filled structure known as the cochlea, contain small hair cells that output electrical signals when deformed. The signal travels through the auditory nerve directly to the brain, which interprets these impulses into sound. Sight (Ophthalmoception) or vision, is the ability of the eye to perceive images of visible light. Light enters the eye through the pupil and is focused through the lens onto the retina on the back of the eye. Two types of photoreceptors, called cones and rods, detect this light and generate nerve impulses which are sent to the brain via the optic nerve. Smell (Olfacception), anosmia is the inability to perceive odor, is closely related to the sense of taste. Chemicals from food or floating in the air are sensed by olfactory receptors in the nose. These signals are sent directly to the olfactory bulb in the olfactory cortex of the brain. Taste (Gustaoception), also known as gustation, this detection is performed by sensory organs on the tongue called taste buds. There are five basic tastes that these organs relay to the …show more content…
This would include just a few Sean Forbes, who became deaf at two months and is an American musician, song writer and Rapper. Also, Ray Charles who became blind at seven is became an amazing Pianist, singer, record producer as well as a film producer. This just proves you can overcome a loss of hearing and sight and this does not mean the end of your life, it could be just the
Anne Louise Oaklander then proceeds to discuss touch. She explains that senses have evolved specialized organs to process senses that were already discussed in this forum. Touch however, as Oaklander explains, can be perceived all throughout the body- something she likes to refer to as “somatosensation.” Oaklander defines somatosensation as: “A product of a number of different kind of sensory processes all chiming in to give you a perception.” All these sensory processes are somehow connected with processes in the brain.
The famous deaf person that I chose is Laurent Clerc being the first deaf teacher of the deaf in America. He was born December 26, 1785 in France and he had become deaf at the age of one. He was involved in an incident when he was left in his high chair for a few minutes by a fire and happened to fall off leading him to burn the side of his face. However, because of the scar that got left behind from the burn had permanently made name sign for him which was two fingers brushed against his right cheek. At the age of seven his parents believed that his deafness could be treated with injections but, in the end learned there was no cure. During his childhood he did not attend any schooling to learn how to write nor read. His family communicated with him through gestures because, he didn’t know sign language as well.
Senses are an important gateway for receiving information about the world around us. However, in Indian culture, various forms of sights such as gaze, glances, darshan were not only used to receive information but were often used to communicate with one another without speaking anything. Hence, sight held a significant position in all major Indian religions.
Christian Jarrett explains that having 5 senses is a myth. Just by defining the word “sense” we can tell that five is inaccurate. If a sense is a way for the brain to receive information about the world and the body, then we will agree that there are more than five. If senses were differentiated depending on the type of receptors, then that will multiply the number of senses even more. So five senses actually makes no sense.
Briefly describe the path of information from the targeted sensory organs (eye, ear, skin, and nose) to the brain.
The documentary of “Through Deaf Eyes” has open my eyes to the deaf culture. The movie has made it “click” that deaf people are just that people and individuals like me. Deaf community has its struggles just like everyone else. They struggle with growing into who they are as a person, harmful situations, and feeling a sense of belonging. They just speak a different language like Italians and Hispanics. Communicating with a different language does not make them lesser than a hearing person. When able to learn to communicate, the deaf are able to learn and gain knowledge just like a hearing person. The only difference is they have to learn more and work harder to achieve their goals and gain knowledge, which a hearing person learns just by hearing their surroundings.
Sense perception is one of our ways of knowing which is critical to our understanding of the world around us. The above quote by William Blake emphasizes how our perception can be easily altered and unclear to us. Blake’s comment was popular in his day and in ours, giving its name to one of the most celebrated rock groups in the world, The Doors. This prescribed title involves what we consider to be the “truth” and our five windows to the world, sight, smell, taste, touch, and hearing inform us constantly about our environment and our accurate perceptions of it. One of the knowledge issues of this prompt is whether or not we can assume everyone has the same concept of “truth”. For the purposes of this paper we will focus on truth being “reality” and what actually exists in our external worlds.
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.
The nose can smell thanks to the ten million scent receptors that make up the Olfactory Epithelium(smell device). The Olfactory Epithelium is located about 7 cm up inside the nose.These receptors can differentiate from over 10,000 different smells. The receptors send signals to the Olfactory Bulb. Those signals then travel to the brain which interprets what you are smelling by combining the different signals of the receptors. Many parts of the brain are affected by these signals.
Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.
So today, I have shared with you my journey in deafness. Being deaf can be hard, but it is not the end of the world. I can do what anyone else can do such as talk, play sports and hang out with friends. Every person’s journey is different. For me the key to success is perseverance.
Perception is a mysterious thing; it faces a lot of misconception, for it can merely be described as a lens, as it decides how someone views the events happening around them. Perception is the definition of how someone decides to use their senses to observe and make conceptions about events or conditions they see or that are around them. Perception also represents how people choose to observe regardless if it’s in a negative or positive way. In other words, perception can be described as people's cognitive function of how they interpret abstract situations or conjunctures around them. All in all, perception can do three things for someone: perception can change the way someone thinks in terms of their emotions and motivations, perception acts
Taste is a sensation created by receptors on the tongue. There are five tastes which are sweet, salty, sour, bitter and umami. Sweet is having the taste or flavour characteristics of sugar or honey while bitter is having harsh, disagreeably acrid taste like aspirin. On the other hand, salty is tasting of something that contained salt or seasoned with salt. Sour is having an acid taste, resembling that of vinegar, lemon juices and so on. Lastly, umami is a strong meaty taste imparted by glutamate and certain other amino acids which often considered being one of the basic taste sensations along with sweet, sour, bitter, and salty.
One sub-system under the sensory system is the visual system; the main sense organs of this are the eyes. The eye is the sensory organ that allows us to detect light from external stimuli. When a light ray is detected, the eye converts these rays into electrical signals that can be sent to the brain in order to process the information and giv...
