The five senses include sight, smell, touch, taste, and hearing. Sight is the power of seeing objects and people. To see we use our eyes, our eye is a sphere with a diameter of about 2.5 cm or 1 inch. Our eyes include the eyebrows, eyelids, conjunctiva, lacrimal apparatus, and extrinsic eye muscles. The eyelids are thin, skin covered folds supported by the connective tissue sheets called tarsal plates and are separated by the palpebral fissure and meet at medial and lateral angles of the eye. The eyelid muscle cause blinking every 3-7 seconds and when the objects get in your eye, the flexibility is activated to protect the eye. The eyelashes also protect the eye. Anything that touches the eyelashes is blown away because it will cause your eye to blink. The conjunctiva in our eyes is a mucous membrane; it helps to line the eyelids. The function of the conjunctiva is to produce a lubricating mucus that prevents the eyes from drying out. A conjunctival sac is where contact lens lies and occurs when the eyes are closed and a slit like space occurs. An inflammation of the conjunctiva is called conjunctivitis and happens when the eye get red and really irritated. The lacrimal apparatus in our eyes drains the lacrimal secretions into the nasal cavity. The lacrimal fluid in the eye cleans and protects eye as it moistens. The fluid contains mucous, antibodies, and lysosome. The extrinsic eye muscles originate and insert into outer surface of the eyeball. The extrinsic eye muscles allow the eye to follow a moving object and provide wires to maintain shape of eyeball and hold it in orbit. When movements of these muscles are not the same, a person cannot focus on images correctly and see two images instead. The eye is called an eyeball and ha...

...cines. They may also help you cope with it by teaching you how to cooperate with noise around you. When doctors check your ears that may find OME, it’s thin and watery. If fluid is still present after six weeks the treatment may include having more observations and having to take tests. For us to tell what foods and scents delight us, we use our sense of smell. Your sense of smell helps us to determine what we like to have to eat and wear on different types of occasions. Your sense of smell can also be used for other things like smelling nature around you and smelling the different kind of foods there are around the world. Smell has a chemoreceptor that respond to chemicals in an aqueous solution. Smell receptors are excited by the airborne chemicals that dissolve in fluids coating nasal membranes. The organ of smell is a yellow patch of pseudostratified epithelium.
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.
Home is experienced in a multitude of ways using our senses. Impressions of our past and present homes materialize from a familiar smell, sight, feeling, taste or sound. We all live in a multi-sensory environment, where we can use one or more of our senses on a daily basis to absorb our surroundings. However, it is easily arguable that although each sense can conjure up a memory, or imprint a grasp of where we live or lived, certain senses are stronger with the recollection or the feelings we have of our home. If we live in the same home as other people, some of us will associate a certain smell to the home, while others will not; or a sound, etc., that I would not associate with that home. I will be pursuing the reasons why we absorb our environments
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.
Now in the short essay, “Us and them”, David Sadaris features great examples of how one’s culture truly molds the way one views the world and how it then affects them in life. In the text Sadaris states, “We never spoke, but I’d pass them in the halls from time to time and attempt to view the world through their eyes” (Page). For Sadaris, this was nearly impossible. In the beginning of his story he explains the black and white contrast between the Tomkey’s and his own family. He talks about his relationship with television and how it was a part of daily life, while the Tomkey’s on the other hand didn’t own a television, let alone even believed in it. Not to mentions the families’ two differences with Halloween or simply the way either family would eat their dinners. This all relates back to the quote and Sadaris’s big misunderstanding with the Tomkey’s. He couldn’t understand due to the lack of knowledge he had about living the way the Tomkey’s did. He said he never even talked to the children, one could say it’s because most are too scared of what they don’t understand. Sadaris gr...
The four main components of the eye that are responsible for producing an image are the cornea, lens, ciliary muscles and retina. Incoming light rays first encounter the cornea. The bulging shape of the cornea causes it to refract light similar to a convex lens. Because of the great difference in optical density between the air and the corneal material and because of the shape of the cornea, most of the refraction to incoming light rays takes place here. Light rays then pass through the pupil, and then onto the lens. A small amount of additional refraction takes place here as the light rays are "fine tuned" so that they focus on the retina.
This paper aims to endorse physicalism over dualism by means of Smart’s concept of identity theory. Smart’s article Sensations and the Brain provides a strong argument for identity theory and accounts for many of it primary objections. Here I plan to first discuss the main arguments for physicalism over dualism, then more specific arguments for identity theory, and finish with further criticisms of identity theory.
Fluid circulating inside the front portion of the eye is produced by a structure called the ciliary body, which is located behind the iris. This fluid moves through the opening of the pupil, passes into the space between the iris and the cornea, and drains out of the eye through a tissue called the angle. With glaucoma, the passing of fluid through the angle is either reduced or suddenly stops, and amounts of fluid inside the eye increase. This high fluid pressure hurts the nerve fibers and the eye's optic nerve and causes blind spots. It may lead to blindness in some cases.

Physicalism is the position that nothing can exceed past what is physically present, and what is physical is all that there can be. This idea is reductive in that it suggests there is no more to the universe than physical matters, including brain processes, sensations, and human consciousness. J.J.C. Smart explains sensations as a means of commentary on a brain process. He believes that, essentially, brain processes and what we report as sensations are essentially the same thing in that one is an account of the other. He writes in “Sensations and Brain Processes” that “…in so far as a sensation statement is a report of something, that something is in fact a brain process. Sensations are nothing over and above brain processes,” (145). Though
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.
“Consciousness is defined as everything of which we are aware at any given time - our thoughts, feelings, sensations, and perceptions of the external environment. Physiological researchers have returned to the study of consciousness, in examining physiological rhythms, sleep, and altered states of consciousness (changes in awareness produced by sleep, meditation, hypnosis, and drugs)” (Wood, 2011, 169). There are five levels of consciousness; Conscious (sensing, perceiving, and choosing), Preconscious (memories that we can access), Unconscious ( memories that we can not access), Non-conscious ( bodily functions without sensation), and Subconscious ( “inner child,” self image formed in early childhood).
The methods used to determine whether the samples are different are Paired Comparison test, Duo-Trio test and Triangle test. Paired Comparison method is the method used to determine whether the two samples differ in a specified dimension such as sweetness or crispness. The two samples are presented to the panelist simultaneously and the panelist is asked to identify the sample that is higher in the specified sensory attribute.
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.
This reflected light passes through the lens and falls on to the retina of the eye. Here, the light induces nerve impulses that travel through the optic nerve to the brain, where it makes an image of the object, and then that image is passed on to muscles and glands.The eye is well protected. It lies within a bony socket of the skull. The eyelids guard it in front. They blink an average of once every six seconds. This washes the eye with the salty secretion from the tear, or lachrymal, glands.
The main purpose of this chapter is: to illustrate that when we practice mindfulness, we are more aware of our senses and can more fully enjoy what they have to offer. Living in an overindulgent, demanding society, individuals lose sight of the simplicities. The five basic senses – sight, smell, taste, hearing, and touch – appear for many individuals at birth, resting unnoticed throughout life. With continuous stimulation from the external environment and internal factors, our senses do not turn on and off. Due to this continuous stimulation, individuals lose appreciation for their senses. By participating in mindfulness, an individual pulls himself or herself from reality, reflecting on their present experience.
