PPT-What are receptor neurons?

Specialized neurons that respond to physical or chemical stimuli Respond by changing ion channels altering graded potentials High graded potential at receptor ending causes rapid firing of its afferent neuron. Nonet. – cell biology. Nonet. – axon transport. Monk – Glia. In the future I will try to include notes/outlines of key points. A couple of these lectures are so broad that that would be difficult. Hopefully these questions give you a better idea of what you are actually expected to know. . 16. Some updates to original. I will probably update more later. Vision. Hearing. Touch. Taste. Smell. Five sensory modalities recognized since ancient times. . Ideal Sensory Receptor. Rapid response.
