List and explain the three general functions of the nervous system
What will be an ideal response?
1. Sensory (input) function–the nervous system uses millions of sensory receptors to monitor changes (stimuli) inside and outside the body; the gathered information is called the sensory function.
2. Integrative function–the nervous system processes and interprets sensory input and makes decisions about what should be done and the magnitude to which it should be done at each moment.
3. Motor (output) function–the process of reaction to stimuli; the body responds by activating muscles that can produce motion or glands that can produce and secrete hormones.
