7/10 Other senses

  1. 1. Other senses By: Justine Yu Madeleine Si
  2. 2. Other senses temperature (thermoception) kinesthetic sense (proprioception) pain (nociception) balance (equilibrioception) acceleration (kinesthesioception).
  3. 3. thermoception Thermoception or thermoreception is the sense of heat and the absence of heat (cold) by the skin and including internal skin passages, or, rather, the heat flux (the rate of heat flow) in these areas.
  4. 4. Mammals have at least two types of sensor: detect heat (temperatures above body temperature) detect cold (temperatures below body temperature).
  5. 5. kinesthetic sense (proprioception) provides the parietal cortex of the brain with information on the relative positions of the parts of the body.
  6. 6. The cerebellum is largely responsible for coordinatingthe unconscious aspects of proprioception.
  7. 7. The cerebellum is largely responsible for coordinatingthe unconscious aspects of proprioception.
  8. 8.  It is distinguished from exteroception, by which we perceive the outside world, and interoception, by which we perceive pain, hunger, etc., and the movement of internal organs.
  9. 9.  There are several relatively specific tests of the subjects ability to propriorecept. These tests are used in the diagnosis of neurological disorders. They include the visual and tactile placing reflexes.
  10. 10. One of the tests is…. Neurologists test this sense by telling patients to close their eyes and touch their own nose with the tip of a finger. Assuming proper proprioceptive function, at no time will the person lose awareness of where the hand actually is, even though it is not being detected by any of the other senses.
  11. 11. Nociception (physiological pain) Signals nerve-damage or damage to tissue. This activity is initiated by nociceptors, (also called pain receptors), that can detect mechanical, thermal or chemical changes above a set threshold. Once stimulated, a nociceptor transmits a signal along the spinal cord, to the brain. Nociception triggers a variety of autonomic responses and may also result in the experience of pain in sentient beings
  12. 12.  The main function of pain is to warn us about dangers. For example, humans avoid touching a sharp needle or hot object or extending an arm beyond a safe limit because it hurts, and thus is dangerous. Without pain, people could do many dangerous things without realizing it.
  13. 13.  The three types of pain receptors are cutaneous (skin), somatic (joints and bones), and visceral (body organs). It was previously believed that pain was simply the overloading of pressure receptors, but research in the first half of the 20th century indicated that pain is a distinct phenomenon that intertwines with all of the other senses, including touch. Pain was once considered an entirely subjective experience, but recent studies show that pain is registered in the anterior cingulate gyrus of the brain.
  14. 14. balance (equilibrioception) It helps prevent humans and animals from falling over when walking or standing still. Balance is the result of a number of body systems working together: the eyes (visual system), ears (vestibular system) and the bodys sense of where it is in space (proprioception) ideally need to be intact.
  15. 15. Balance skill development in children
