Human Physiology Chapter 14– The Somatic Nervous System Study Guide This is the material you should know for the exam. What are the functional categories of sensory receptors and what modalities does each type of receptor transduce? What is a receptor potential? How is a receptor potential different/like an action potential? What is the difference between a tonic and phasic receptor? What are the somatosensory modalities? Where (in the brain) is somatosensory information sent? Where are the receptors for the somatic senses located? What kind of receptors are touch receptors? Be familiar with Pacinian and Ruffini corpuscles. What do nociceptors detect? Be aware of the receptive field and how it varies inversely with the density of receptors. If there is a low density of sensory receptors, does that mean large or small receptive field? What is the two-point touch threshold? Where are the olfactory receptors located? Olfactory receptors send axons to _______________ and the information is eventually sent to the _____________ cortex, located in the ______________lobe. What can our taste buds sense? Be familiar with the function of the taste bud, and that the cells within the taste bud are modified epithelial cells that can be depolarized.

    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.
