  • If you are that close to a black bear sow and her cub, you are going to win a Darwin award.  Dude would have been better off using his normal eyesight and talking loudly.
  • The section on the nervous system isn’t wrong, but it is missing entire chunks.   Let me see if I can straighten it out with some oversimplification.
      • The nervous system has two divisions: the central nervous system and the peripheral system.
        •  The central nervous system (CNS) consists of the brain and spinal cord.
          • The brain can be roughly divided into three areas – the front brain, the midbrain and the hindbrain.
            • The front brain handles cognitive tasks like “I can write a blog post!” or “That picture seems to be of a black bear, not a grizzly bear.”
            • The midbrain handles emotion, memory and routing information to the correct section of the front brain.
            • The hind brain handles automatic bodily functions that are critical for life like breathing, blood pressure, heart-rate, etc.
        •  The peripheral system (PNS) is the nerves outside of the brain and spinal cord.
      • The PNS has two divisions: the somatic nervous system and the autonomic nervous system.
        • The somatic nervous system deals with skeletal muscles.
        • The autonomic nervous system deals with smooth muscles (which are involuntary muscles in the body), organs and glands.
      • So, a more accurate way of describing control would be “The front brain handles conscious decision making while the autonomic prepares the body for action.”  This becomes important later in the lesson.
