Sensory cell

can also be called a receptor or receptor cell. In addition, according to the species of suitable stimulation, it can also be specifically referred to as optical cells, flavor cells, and the like. On animals, it is generally linked through nerve fibers and the central nervous system and the neural network. Some are individually dispersed in the body surfaces and organs, and some are gathered in the sensory organ. In the case of invertebrates, in most cases itself is a bipolar neuron, a dendritic formation of a sensing region (primary sensory cells), but in the vertebrate body, like a cell transformation from epithelial cells (times Level sensory cells). In primary sensory cells, the cell body is disengaged from the upper skin to the deep protrusion (neural fiber) to the stimulating sensor surface, wherein the pernia is formed in the epithelium to form a sensitivity protrusion or free nerve end. The sensory cells associated with the skin feel (tactile, temperature) are mostly in this form. In the vertebrate, the sensory cell body even has a long-standing back to the spinal god of the nerve. Excited after the occurrence of nerve cells, the process of transforming into a repetitive nerve impulse in neutral nerve fibers can be used in detail, and the cellular electrodes can be used in detail, and most of them cause a cell part or all of the polarization. It is a sensor potential.
