Chapter 17: The Special Senses I. An Introduction to the Special Senses The state of our nervous systems determines what we perceive. 1. For example‚ during sympathetic activation‚ we experience a heightened awareness of sensory information and hear sounds that would normally escape our notice. 2. Yet‚ when concentrating on a difficult problem‚ we may remain unaware of relatively loud noises. The five special senses are: olfaction‚ gustation‚ vision‚ equilibrium‚ and hearing. II.

Conductive hearing loss "occurs when the eardrum‚ bones and membranes don ’t properly transmit vibrations to the cochlea..." this may be caused by a traumatic head injury or the patient could have been born with a birth defect (http://www.a1-hearingaid.com/howwehear.htm). Sensorineural hearing loss "is characterized by deterioration of the cochlea." These causes may include the aging process‚ excessive exposure to loud noise ’‚ viral infection or in some cases‚ it may be spontaneous

Sensing the World – Basic Principles * Bottom-up processing suggests that we attend to or perceive elements by starting with the smaller‚ more fine details of that element and then building upward until we have a solid representation of it in our minds. * Top-Down Processing states that we form perceptions (or focus our attention) by starting with the larger concept or idea (it can even be the concept or idea of an object) and

Effects of Loud Music Suman Shreshta Byanju Research Paper Professor: Merry Bodner Date: 11/09/2013 Abstract Music at 85 decibels or higher can cause different health problems. Loud music could develop noise-induced hearing loss or tinnitus in an individual and can permanently damage auditory nerves of the human brain. Researchers have found that loud music reduced the memory recall power and reaction time of an individual. Further‚ it could impair the decision-making ability of peoples and

Every second of life‚ the senses are functioning to connect the internal or physiological body to the external world or vice-versa. Through man’s development in life (from birth to death)‚ the senses are continuously affected by one stimulus after another. The process of accepting the stimulus by the sense is called sensation.

channels stay open a lot longer causing depolarization and excessive sound presence even though it is not present. Symptom of Tinnitus include hearing sounds such as ringing‚ whistling‚ buzzing‚ and clicking. Tinnitus is caused by loss of hair cell in cochlea and when these hair cells are damaged‚ they trigger random electrical impulses to the brain. These impulses cause hearing sounds such as ringing‚ buzzing and clicking. Tinnitus is a fairly common disease and most of the time it points to a deeper

The human body has the ability to understand the environment around it by using its senses. The five basic human senses are hearing‚ sight‚ touch‚ smell‚ and taste. Anytime one of these senses is triggered by a specific stimulus the signal is transmitted to the brain in order for the information to be interpreted. This transmission process is known as perception. First the body will experience an external stimulus‚ the sensation. Then this information will be transformed into electrical stimulation
