Dense Spot

**The macula densa** is a cellular layer that is located on the periphery of the retina, characterized by relatively high photoreceptor activity and close connection with ganglion cells, as well as slow neuronal transit. Translated from Latin, the stain is translated as poppy. The term "macula" is used to refer to the central part of the retina. That is, dense areas are areas of the retina with an average density of neurons - the macular region. The macula is a mesh structure in the central zone of the visual analyzer. The number of fibers involved here is high, which ensures the perception of rich photosensitive color information and high quality. The structure of the macula is responsible
