SENSORY ORGANS Introduction The knowledge of the world around us stimulates our sensory organs to provide us with the information of what is going on around us. All sensory information is picked up by the sensory receptors‚ specialised cells that monitor internal and external conditions. Examples of sensory organs are: SENSE ORGAN Eye Ear (Organ of Corti) Ear (Semicircular Canals) Ear (utricle and saccule) Olfactory mucous membrane Taste Buds Skin Skin Skin Skin Various Muscle Spindle Golgi tendon

of available donor organs provides little to no hope for patients wishing to have a chance at new life. According to the Texas Organ Sharing Alliance‚ there were 79‚466 patients on the U.S. National Waiting List as of January 1‚ 2002‚ with only 6‚148 donors in the country that year. In response to the organ shortage‚ scientists have made recent advances in transplant technology with the development of two new types of organ replacement: xenotransplantation and artificial organ replacement; the latter

Organ Printing Bioprinting is a relatively new field that involves creating living tissue with a three dimensional printer. The process of 3D printing is becoming increasingly popular in many fields as it allows for the direct digital manufacture of a wide variety of plastic and metal items. While this technology is revolutionizing by itself‚ it is now being applied to the field of tissue engineering to produce biological tissue in the form of bioprinters. These devices artificially construct living

Mechanical Organs Daily life for a person with naturally good health makes an average day possible‚ but a person with poor health due to internal organ problems can face many challenges. If a person has bad knees or poor eyesight‚ or even malfunctioning kidneys or heart‚ the only way to go about solving any one of those problems is to see a doctor and check out the options to fix the problem. Whether a person needs to be put on a transplant list or have surgery right then and there‚ it can be

Every year‚ there are suspicious deaths‚ in which the victims had their organs removed. In addition to con artists and illegal doctors‚ there are extreme cases in which people are murdered for their organs. A few cases from

The Senses The sensory system involves hearing‚ touching‚ tasting‚ smelling‚ and seeing‚ which provide data for perception. The eye is a sensory organ held by an orbit that allows vision (a detection of light in a way that provides mental images of objects) and holds photoreceptors. Photoreceptors are used to absorb light energy‚ which are bent by a transparent unit called the lens. Some photoreceptors in the eye are the rod cell and cone cell. Rod cells are used in dim light for coarse images and

Organ Senses Definition of each Sense Organ 1.) Eyes -The human eye is an organ that reacts to light and has several purposes. As a conscious sense organ‚ the mammalian eye allows vision. Fun Fact: *In the dark‚ a substance produced by the rod cells increases the sensitivity of the eye so that it is possible to detect very dim light. 2.) Nose - The nose is the organ responsible for the sense of smell. The cavity of the nose is lined with mucous membranes that have smell receptors connected

Honors Activity 6.3 Organ Transplants In order to prevent the rejection of transplanted organs in a person’s body‚ immunosuppressive therapy is necessary. These drugs have saved many lives and extended many others. The number of patients taking immunosuppressive drugs is not decreasing and at the same time doctors following up their patients after an organ transplant must be very vigilant and need to monitor the patience response to the therapy very closely. Unfortunately science has not yet
