1. What is the law of specific nerve energies? Be able to name the five types of receptors. Each receptor that you have in your body was designed to transmit one type of sensation. It monitors 1 thing: 1. Mechanoreceptors a. Receptor undergoes mechanical distortion. b. Ex.) Pressure, Force, etc. 2. Thermoreceptors a. Cold receptors b. Warm receptors 3. Nociceptors (Pain) a. Free nerve ending b. Ex.) Exposed nerve in tooth from cavity. 4. Electromagnetic receptors a. Vision i. Rods (Black & White) ii. Cones (Color) 5. Chemoreceptors a. Taste i. Taste buds b. Smell i. Receptors in the olfactory c. Arteriol O 2 i. Receptors of aortic & carotid bodies d. Osmolarity e. Blood O 2 f. Blood glucose 2. What is meant by receptor adaptation? What is a tonic receptor? What is a rate receptor or phasic receptor? Be able to give examples of each. Receptor Adaption - A property of every receptor. - If we keep the same stimulus strength can the firing continue at the same frequency. --Tonic - Keep same firing rate. - Little or no change - - Phasic - Same as rate receptors - Strength of firing drops rapidly Slow Fast Tonic Phasic/Rate Nuclear Chain Nuclear Bag

    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.
