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.
Best Answer: Yes, removing it from the thermometer would be dangerous. Plus, your thermometer won't work very well after that. Mercury, as a molten (liquid) metal is actually pretty safe, except for one flaw. It evaporates. It is the mercury vapor that is problematic. Breathing mercury vapor allows it to enter the body, and the body has no way of getting rid of it, so it can accumulate with repeated exposure.
