generates heat that is required for maintenance of a constant core temperature D. Nervous System 1. coordinates and regulates body temperature along with endocrine system 2. organs are: a) brain b) spinal cord c) nerves 3. primary functions are: a) body functions b) communications c) integration 4. primary functions accomplished by: a) generation (to start) b) transmission (to send out a signal) c) integration (bringing in) d) recognition...of special nerve impulses 5. impulses permit rapid precise control of diverse body functions 6. elements recognize certain stimuli a) light b) pressure c) temperature 7. this information is processed in the brain 8. nerve impulses cause muscles to contract and glands to secrete 9. the study of the nervous system is called neurology or neurobiology E. Endocrine System 1. has specialized glands 2. glands secrete chemicals called hormones 3. hormones remain regulators of: a) metabolism b) growth and development c) reproduction 4. this system performs same functions as nervous system a) communication b) integration c) control

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
