Another way that receptors can be classified is based on their location relative to the stimuli.

Rod Pacinian corpuscles, Ruffini endings, and Krause end bulbs detect pressure. Both primary somatosensory cortex and secondary cortical areas are responsible for processing the complex picture of stimuli transmitted from the interplay of mechanoreceptors. Special pressure sensors called baroreceptors (or venoatrial stretch receptors) located in the right atrium of the heart detect increases in the volume and pressure of blood returned to the heart. (credit: modification of work by Wbensmith/Wikimedia Commons; scale-bar data from Matt Russell). These receptors are the main sensory cells in the tactile system. Somatosensation is the group of sensory modalities that are associated with touch and limb position. Treated by convex lens. They are found primarily in the glabrous skin on the fingertips and eyelids. The general senses can be divided into somatosensation, which is commonly considered touch, but includes tactile, pressure, vibration, temperature, and pain perception. These categories are based on the nature of stimuli each receptor class transduces. Listing all the different sensory modalities, which can number as many as 17, involves separating the five major senses into more specific categories, or submodalities, of the larger sense. ANAPHY SPECIAL SENSE NOTES.docx - THE GENERAL SENSES RECEPTORS 1 They are rapidly-adapting mechanoreceptors that sense deep, transient (not prolonged) pressure, and high-frequency vibration. 4) Bipolar cells.
