The triclinic shape of copper sulfate can be seen in this cluster of crystals. Copper sulfate crystals are somewhat strange. Some crystals can hold their color for years with no change, while others dehydrate and turn into a white powder. This crystal of copper sulfate is nearly twenty years old.ne of the very best chemicals for growing crystals is copper sulfate. The only trouble with it is that is a poisonous chemical compound. Because of its poisonous nature, it has been used to kill tree roots in sewers. A solution of copper sulfate is simply flushed down the toilet to kill tree roots.
A sensory system is a part of nervous system consisting of sensory receptors that receive stimuli from internal and external environment, neural pathways that conduct this information to brain and parts of brain that processes this information.
From Wikipedia, the free encyclopedia. Sensory neurons are nerve cells that transmit sensory information (sight, sound, feeling, etc.). They are activated by sensory input, and send projections to other elements of the nervous system, ultimately conveying sensory information to the brain or spinal cord.he somatic sensory system includes the sensations of touch, pressure, vibration, limb position, heat, cold, and pain. The cell bodies of somatic sensory afferent fibers lie in ganglia throughout the spine. These neurons are responsible for relaying information about the body to the central nervous system.
