44.4 Electromagnetic Reception

  • They respond to local tissue damage or stimuli that may cause it, with the help of the skin of its bill that can detect small damage.
    • Nociceptors can't respond to electric currents from its prey.
  • This feat is from damaged cells.
    • Small particles of iron oxide in the beaks of damaged cells allow them to release a number of substances, including acids and small signaling molecule called prostaglandins, which act as a compass.
    • The magnetite particles that cause inflammation and make nociceptors more sensitive to pain respond to the Earth's magnetic field.
    • Pigeons were placed individu to reduce pain.
  • The nociceptors travel to the tube.
    • When the tube was placed in a magnetic field, pigeons looked at the cause of the pain.
    • The limbic system, which holds memories of the tube, is also sent to which end is based on the magnetic signals.
    • In another experiment, the pigeons lost this abil and emotions associated with pain, and to the reticular formation in ity when their beaks were anesthetized or cooled down.
  • Magnetic field sense is not unique to birds.
    • Magnetite can be found in the heads of migratory fishes such as rainbow trout.
  • This probably doesn't explain the extraordinary many animals.
  • There are pits on each side of the head that animals use to sense their surroundings.
  • There is a wide range of the waves emitted by live animals.
    • The snake moves its head back and forth between the visible light and the electrical light until both pits detect the same intensity of radiation.
    • The prey is centered in front of the snake.
  • The ability of some animals to sense electric long-distance migration or low-light environments will be examined.
    • When light and magnetic fields are present.
  • Many animals have the ability to detect the presence of nearby prey.
  • The more ways an animal can detect other animals, the better it is at avoiding danger or getting food.
    • In fishes, specialized sensory structures detect electric fields in the environment.
    • There are two types of electrical activity.
    • Many fishes living in dark waters can detect the weak electric field generated by the muscles and nerves of other animals.
    • In order to do this, they use sensitive electroreceptors located in the head region.
    • The importance of this sense for their sur vival can be seen in the fact that these sensory receptors are as heavily innervated as the eyes of these fishes.
    • The rays and sharks can detect the small signals of prey hidden beneath a layer of sand on the ocean floor.
  • The fish can sense a white-lipped through sensory pits.
    • If a pit viper moves close to the animal, it will detect the heat given off by the prey.
