Where is the most highly developed sensitive area for touch?
- A.
Back of the shoulders
- B.
Tip of the tongue
- C.
Bottom of the foot
Correct Answer
A. Back of the shouldersExplanation
Touch is more sensitive in some parts of the body than in others. This difference is due to the fact that the end organs for touch are not scattered evenly over the body, but are arranged in clusters. The feeling of pressure is keenest where there are the greatest number of end organs. It is most highly developed on the tip of the tongue, and is poorest on the back of the shoulders. The tips of the fingers and the end of the nose are other sensitive areas.Rate this question:

How are different smells distinguised?
- A.
By the chemical gas an object gives off
- B.
The nose has different receptors for different smells
- C.
Scientists do not know exactly
Correct Answer
C. Scientists do not know exactlyExplanation
Scientists do not know exactly how different smells are distinguished. One explanation is that molecules of certain odors become more quickly and more strongly attached to the mucus at a particular place on the turbinates than do other molecules. Therefore, molecules of certain kinds of odors will always stimulate the same receptor cells on the conchae. According to this theory, an odor is distinguished by how fast and where its molecules become attached to the receptor cellsRate this question:

Some scientists think a fifth distinct taste, called umami, can be detected. This taste is usually described as “savory” or “meaty.” Japanese scientists were the first to describe it, The sensation of umami is caused by a chemical called glutamate. Glutamate is found in many protein-rich foods. However, not all scientists agree that umami constitutes a fifth category of taste.Rate this question:
