What Are The Five Senses?

1341 Words3 Pages

Each person has five senses organs (eyes, ears, nose, tongue and skin) that take in information from your environment and send it to your brain. Your brain then processes the information and tells your body how to respond. Your nervous system is responsible for ignoring unnecessary data. Sight is the capability of the eyes to focus and detect images, hearing or audition is the sense of sound perception, taste refers to the capability to detect the taste of substances such as food, smell refers to the capability of detecting odors and touch responds to pressure receptors. There are about 6 million specialized cells just for smelling. Separate senses with their own receptor organs, taste and smell are nonetheless intimately entwined. This …show more content…

The general senses are pain, temperature, touch, pressure, vibration, and proprioception. Receptors for those sensations are distributed throughout the body. Special senses are limited to the head, such as the ears and eyes. A sensation is how receptors transmit information to the brain and perception is how the brain processes that information. The five types of receptors are chemoreceptors (sensitive to changes in chemical concentrations), pain receptors (sensitive to tissue damage), thermo receptors (sensitive to temperature change), mechanoreceptors (sensitive to mechanical forces), and photoreceptors (sensitive to …show more content…

Rods are responsible for vision at low light levels they do not mediate color vision, and have a low spatial acuity. Rods are more sensitive to light then cones. Cones are active at higher light levels and are capable of color vision and are responsible for high spatial acuity resulting in sharp images. Rhodopsin is the light sensitive pigment in rods. Rhodopsin molecules break down into a protein called opsin and an organic compound called retinal which manufactures vitamin A. Iodines are the light sensitive pigments of cones. They contain different proteins than the

    Each sensation has its own neuronal receptor, such as: “mechanosensation, thermosensation, vibration, joint position, chemosensation, and electrosensation.” Oaklander then discusses “nocifensive sensations,” or senses that defend us from danger, such as pain and itch. These sensations trigger reflexes and strong movements. However, something that is often left undetected is chronic neuropathic pain, which can cause nerve damage. Shingles is a result of chronic neuropathic pain.

  • Roles Of Perception In Critical Thinking

    Our five senses –sight, hearing, smell, taste and touch help the ways in which we perceive the world around us. And while they seem to work independently at time they can effect each other and the way we comprehend something. Seeing something pretty, touching something soft, eating something cold and smelling something rotten are the sense we use to connect with the world around us and will all effect how we move forward in that situation. When you look at the top picture say the color of the word not the word itself. It is harder than it seems and takes a little practice to do it efficiently. It is because we see the spelling we were taught not the color it was written in. It is hard to process it the other way, but not impossible. Take the bottom picture for another example is this a

    Lastly, behavior can also be determined by sensation and perception, the stages of processing the information gathered from the senses. Sensation and perception depicts the world for humans. Without them, humans would not be able to truly experience what is going on around them. The first step, sensation, is the gathering of the information from the outside would through the five senses: sight, hearing, taste, touch, and smell. The information is then organized and interpreted by the brain through

  • Sensation And Senception: The Process Of Sensation And Perception

    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.

  • The Processes of Visual Perception and Visual Sensation

    1240 Words  | 3 Pages

    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.

  • What it means to be human

    First, one must have the five senses; taste, smell, hear, see, and feel. Yes, these are physical aspects, however, these senses are what any human needs to be, human. For example, the human body needs to be able to taste. It must ingest food, and the food must appeal to a decent taste. A human must also be able to smell, so one may smell a poisonous gas, delicious food, or any other stench that may linger in the air. To be able to hear, enables the human to hear danger or a noise that appeals to them. When seeing, danger is also noted as well as the care of others. When one feels, the object that is being felt may make the person feel comfortable. Not only the sense of touching, but feelings.

  • Anosmia

    1633 Words  | 4 Pages

    Have you ever wondered what your life would be like if you did not have one of your five senses? At some point in our lives we have all seen a blind or deaf person but how often do we wonder what it would be like if we were in their shoes? Many people take their senses for granted, not giving much thought to the fact that something as simple as bumping your head the wrong way or getting a cold could take away your sense of smell forever. Anosmia is the total loss of the sense of smell and affects approximately two million Americans (Wuensch, 2001). Of all the five senses, smell seems to be the least appreciated due to our society's beliefs that sight and hearing are more important for survival (Gillyatt, 1997). For most people, once they start to notice a decrease in their hearing or sight they go to the doctor almost immediately to fix the problem. However, because the sense of taste and smell are so closely related, many people attribute the problem to a lack of taste and do not see their doctor until the damage is irreversible (Thomson, 2001). Anosmia is a condition in which although there are mild cases, more serious cases do exist which may jeopardize the victim's life. This disorder not only affects the person's life and safety, but also has psychological effects as well . In any case, anosmia should not only be taken seriously, but research should be continued in the hopes of finding better treatments.

  • The Common Sense: The Five Sense Of Perception

    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.

  • Auditory Sensations

    Along with vision, hearing is one of the most important senses that humans have. We use it to communicate, learn, and stay aware of our environment. In fact, hearing is the only sense that never stops receiving sensory input. While all of our other senses become drastically less sensitive when we are sleeping, our brain still processes auditory information to awaken us the second something is wrong. Although this may have been more practically used before people slept safely in homes, it’s still useful for hearing a fire alarm or our alarm clock in the morning. We are able to hear by processing sound waves. This energy travels through the delicate structures in our ears to be transformed into neural activity so that we can perceive the sensory information we receive (Myers, 2010).
