THE NERVOUS SYSTEM

  • The nervous system is a network of nerve cells that transmit nerve impulses.
  • It consists of the brain, spinal cord, sensory organs, & all of the nerves that connect them to the body.
  • Central nervous system is made up of the brain & spinal cord.
  • Peripheral nervous system is made up of all the nerves outside of the central nervous system.

WHY IS THE NERVOUS SYSTEM IMPORTANT?

THE 5 SENSES

  • The 5 senses are sight, taste, smell, touch, & hear.
  • They are essential to everyday living.
  • They let your brain know what is going on around you.
  • They warn you during danger.

SIGHT

  • Sight helps us see where we are going.
  • Sight is the most important sense.
  • Sight helps us gather light.
  • Images are sent upside down, but our brain makes sense of what it receives by turning it right side up.
  • The brain uses the images from 2 eyes to create a 3D image.

TASTE

  • Taste comes from the taste buds on our tongue.
  • The tongue is able to taste 4 flavors: salty, sweet, sour, & bitter.
  • It picks up texture and temperature in your food.
  • Taste buds send a signal to our brain to determine if our food is safe.

SMELL

  • Our sense of smell is able to identify 7 sensations: camphor, musk, flower, mint, ether, acrid, and putrid.
  • Smell is important to be able to taste.
  • We never experience the same smell twice.
  • Dogs have the strongest sense of smell.
