      1. 1.functions of the SENSES to organism
        1. A. senses give information/meaning about environment
          1. Some basic functions
            1. 1alerting function
            2. 2localization
            3. 3recognition (self, kin, others, enemies)
            4. 4social/sexual/reproductive communication
        2. B. Senses give information about internal states and "self"
          1. pressure, tension, glucose, oxygen, orientation, balance
        3. CSenses serve as a selective filter of information
        4. D.Three questions concerning human senses
