THE SMELL SENSE

Olfaction is the sense of smell. The sense of smell is how a human or animal notices a smell by using the nose. Many animals have better noses than people, some animals can detect small particles in the air or sometimes water that people cannot.

   People have special cells in the nose that can detect some chemicals. These are special nerve cells attached to the olfactory epithelium. All vertebrates have these cells. The smell is first processed by the olfactory system. The information is given to the olfactory bumb in the front of the forebrain.

In insects, smells are sensed by sensilia on the antennae and first processed by the antennal lobe.
As we have said before, the taste and the smell sense were did by the same group. They had to explain and interact with the rest classmates in order to teach them what are these senses about.
