Senses by ELIZABETH CARLS https://padlet.com/carlseli/frzbzmwv1m1n en-us 2017-11-27 17:21:49 UTC 2017-11-28 16:04:34 UTC hello@padlet.com Two major categories of sensory receptors: carlseli https://padlet.com/carlseli/frzbzmwv1m1n/wish/210964061 1. Somatic senses
2. Specialized sensory Organs]]> 2017-11-28 15:43:21 UTC https://padlet.com/carlseli/frzbzmwv1m1n/wish/210964061 Somatic Senses carlseli https://padlet.com/carlseli/frzbzmwv1m1n/wish/210965115
  • Receptors associated with the somatic senses of touch , pressure, temperature, and pain form one group. 
  • These receptors are widely distributed throughout the skin, muscle, joints, and deeper tissues.

  • Special senses of smell, taste, hearing, vision, and equilibrium.

  • Chemoreceptors  - are stimulated by changes in the chemical concentration of substances. (Taste and smell)
  • Pain receptors - by tissue damage
  •  Thermoreceptors - by changes in temperature
  • Mechanoreceptors - by changes in pressure or movement
  • Photoreceptors  - by light energy

  • Are feeling that occur when the brain interprets sensory impulses
  • All nerve impulses that travel away from sensory receptors into the central nervous system are alike, the resulting sensation depends on which region of the brain is stimulated.
  • An example would be the smell of a Apple scented candle.

  • The brain projects the sensation back to its apparent source
  • Projection allows a person to pinpoint the location of stimulation: thus the eyes seem to see, and the ears seem to hear.

  • When sensory receptors are continuously stimulated, many of them undergo an adjustment called sensory adaption.
  • As receptors adapt, impulses leave them at decreasing rates, until finally theses receptors may stop sending signals.
  • Example: a person walks into a room with a strong smell, the longer the person is in the room, the less noticeable the smell is.
