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.
Myth: Mercury bulb thermostats are hazardous and should be removed. Fact: The small amount of mercury in a thermostat is safely encased in a glass bulb. Unless the bulb is broken, which isnât going to happen unless someone smashes it, the mercury is perfectly safe.ome are specific to mercury-bulb thermostats. And some thermostat myths apply just to hydronics. Typical of electro-mechanical, non-electronic, mercury-bulb thermostats are the Honeywell T87 and the White Rodgers 1E56.
