Document Summary
General senses were somatic senses (tactile, thermal, pain, and proprioceptive) and visceral sensations. Their receptors were scattered throughout the body and were simple in structure. The special senses, on the other hand, are involved in smell, taste, vision, hearing, and equilibrium. Their receptors are anatomically distinct from one another and are concentrated in specific locations within the head and are usually embedded in the epithelial tissue within complex sensory organs (i. e. eyes and ears): olfactory epithelium: Both smell and taste (gustation) are chemical senses, and the sensations arise from the interaction of the molecules with smell/taste receptors. To be detected by either sense, the stimulating molecules must be dissolved. To make it possible for the nose to recognize more than 10 000 different odors, the nose contains 10 million receptors for the sense of smell (olfaction), which is contained within the (cid:862)olfa(cid:272)tor(cid:455) epitheliu(cid:373)(cid:863).
