Human Receptors

  1. 1. Interaction and Coordination ●Systems involved. ●Receptors. ● Skin receptors ● Ears ● Eyes ●Neurones.
  2. 2. Systems involved ● What is the name of the organs which obtain information? ● ● What systems analyze the information? ● ● What is the name of the organ responsible for carrying out the response? ●
  3. 3. Systems involved ● What is the name of the organs which obtain information? ● RECEPTORS ● What systems analyze the information? ● NERVOUS AND ENDOCRINE SYSTEM ● What is the name of the organs responsible for carrying out the response? ● EFFECTORS

  7. 7. Receptors Skin Receptors
  8. 8. Receptores Receptores de la piel
  9. 9. Receptores The skin layers
  10. 10. Receptores The skin layers MELANOCYTE
  11. 11. PIEL Skin and sun:
  12. 12. Receptors Skin Problems: Moles: Moles are bening tumors, normal parts of the skin. Moles can be flat or raised, and they can be red, brown, black or skin-colored.
  13. 13. Receptors Skin Problems: If a mole start changing in size, color or shape, or if it bleeds and doesn't heal on its own in three weeks, it should be evaluated by a doctor to make sure it is not turning into a skin cancer. MELANOMA
  14. 14. Piel Skin Diseases: MOL → MELANOMA
  15. 15. Piel Skin Diseases: MELANOMA
  16. 16. Receptors Skin Problems: Acne presents itself as red bumps and pimples.ACNE
  17. 17. Receptors Ear: Recommended:
  18. 18. Receptors Ear: The eardrum flexes when sound waves coming. The flexing is transported and magnified by the three tiny bones to the round window of the cochlea.
  19. 19. Receptors Ear: Draw the ear And write the name of each part
  20. 20. Receptors Ear: The cochlea is the sense organ that translates sound into nerve impulses to be sent to the brain. Hair cells are the sensory receptors of the auditory system
  21. 21. Receptors Ear: The cochlea is the sense organ that translates sound into nerve impulses to be sent to the brain.
  22. 22. Receptors EYES: Anathomy.
  23. 23. Receptors EYES: Anatomy.
  24. 24. Receptors EYES: Retina: There are two types of photoreceptors in the human retina, rods and cones. The retina is a thin layer of specialized cells located at the back of your eye that help to transmit information provided by light to our brain.
  25. 25. Receptors EYES: Retina Rods are responsible for vision at low light levels Cones are active at higher light levels, are capable of color vision
  26. 26. Receptores EYES: Lens Crystalline lens: is a transparent structure. It can change the shape to change the focal distance of the eye so that it can focus on objects at various distances.
  27. 27. Receptors EYES: Lens
  28. 28. Receptors EYES: IRIS The colored part of the eye is called the iris. It controls light levels inside the eye similar to the aperture on a camera. The round opening in the center of the iris is called the pupil
  29. 29. Receptors EYES: IRIS
  30. 30. Receptores EYES: Problems The myopia eye is usually longer than a normal eye, and its cornea may also be steeper. Therefore, when light passes through the cornea and lens, it is focused in front of the retina. This will make distant images appear blurred. The Hypermetropia eye is the oposite case.
  31. 31. Receptores EYES: Problems Astigmatism: Asymmetric steepening of the cornea or natural lens causes light to be focused unevenly
  32. 32. Receptors EYES: Problems
  33. 33. Receptors EYES: Problems Cataract: is an eye disease in which the clear lens of the eye becomes cloudy or opaque, causing a decrease in vision.
  34. 34. Receptors VISTA: Problems Glaucoma: Is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision (peripheral vision). Glaucoma is usually, but not always, associated with elevated pressure in the eye (intraocular pressure). Generally, it is this elevated eye pressure that leads to damage of the eye (optic) nerve.
  35. 35. Receptores VISTA: Problemas Retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue.
