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.
When elemental mercury is spilled or a device. containing mercury breaks, the exposed elemental mercury can evaporate and become an. invisible, odorless toxic vapor. This happens with the most known devices such as barometers, blood pressure gauges, thermometers, etc. Both the breakage as the mismanagement of these.
