SENSORY ORGANS ANATOMY. 1  Sensory organs are very highly developed and specialized organs that are an extension of the central nervous system, with a sole function to take in information and relate it to the brain. The sensory neurons are highly adapted to detect changes of both external and internal changes in the environment and report these changes to the brain.
If you break a mercury thermometer or light bulb, a small amount of liquid mercury may spill out. Liquid mercury can separate into small beads, which can roll some distance away. The mercury may also evaporate into vapour. However, this small amount of mercury is extremely unlikely to cause problems for your health.
To get the mercury in you will have lead to a glass breakage which will be affecting your mouth, throat and stomach. You would probably need medical assistance for this alone. Mercury is venomously poisonous (it is also very reactive - try dropping mercury onto a piece of aluminium and see what happens). I have been told that any mercury dropets in you will eat through your stomach lining and much other flesh it touches. So, you have two worries, not just one (toxicnous, organic attack).
