The sense of Smell

Dakota Byrd

10 facts about it

We can discern about 10,000 different smells.

We have 500 different receptor types.

We have 12,000,000 olfactory receptor cells.

Our olfactory sense start in the nasal cavity.

The olfactory receptor cells are bipolar neurons.

The cortex for smell interpretation is located deep in the temporal lobe.

The right hemisphere controls the left side of our bodies because most of the fibers of the lateral corticospinal tract cross over at the lower portion of the medulla oblongata.

The proportion of the sensory cortex to the size of body region is uneven.

The sense of taste and smell are related because they use the same type of receptors and are stimulated by molecules in solutions or air.

Taste and odor stimuli are molecules taken in from the environment.
