Senses are a vital necessity in human life. Senses consist of sight, sounds, smell, tastes, and texture. A main function of the senses is to maintain homeostasis. There are two senses; general and special. “General senses are those with receptors widely distributed throughout the body, including skin, various organs and joints” ( ,Pg. 444). “Special senses have more specialized receptors and are confined to structure in the head, such as eyes and ears”( ,Pg.444). Over time, scientists have discovered that each little receptor places a different role. “A raw form in which these receptors send information to the brain is called sensation”( ,Pg 444). Sensation is the feeling you get when your body makes you aware of your surroundings. …show more content…
They are both dealing with change in temperature. “At intermediate temperature the brain interprets sensory input from different combinations of warm and cold receptors as an intermediate temperature sensation”( ,Pg 446). Other than temperature senses we have pain senses too. “Some pain receptors are most responsive to chemicals such as hydrogen ions, potassium ions, or specific breakdown products of proteins histamine and acetylcholine” ( ,Pg 447). Visceral pain falls under pain sensory. These visceral pain receptors are the ones who detect where the pain is located. Although you can detect a painful sensation in your body, the brain can trick you with referred pain. “Referred pain may derive from the common nerve pathways that sensory impulses coming both from skin areas and from internal organs use” ( …show more content…
Everyone had heard of tastes buds before. They allow for us to taste the food we are eating. The bubs are found on the tongue along with papillae. Inside taste buds are a taste cell. (It takes the function of a sensory receptor) “Each of our 10,000 taste buds have up to 50 to 150 taste cells” ( ,Pg 455). Each bud has a taste pore and taste hairs. With the sense of taste comes along with a mixture of chemicals. To receive sensation on taste there is chemical formulas the trigger your brain. “The five primary taste sensations are sweet, sour, salty, bitter and umani” ( ,Pg 455). The sections of the tongue are arranged so that they all have powering sensations to allow us to perceive food. Sweet receptors are triggered by the intake of crabs. Salty receptors are found through sodium and bitter senses are encouraged by organic
