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.
Many thermostats used in residences, businesses and industrial settings all used to contain mercury at one point. When the seasons change many people start thinking about upgrading their heating and cooling systems, which typically means replacing their old thermostats with new ones.Do NOT throw your old thermostat in the trash if it contains a mercury switch! You should dispose of it properly.Each mercury thermostat has an average of 4 grams of mercury in it. This seemingly small amount could pollute an 80-acre lake or 20 million gallons of water and result in a fish consumption advisory lasting a year.ach mercury thermostat has an average of 4 grams of mercury in it.
