Question

After suffering a head injury, doctors discover that your

olfactorybulbs have been completely severed from the axons of the
olfactoryreceptor cells. Check all true statements that apply to
thisinjury.

1. Youwill be unable to smell.
2. Youwill be unable to taste.
3. Yourolfactory receptor cells will no longer be able to respond
tomolecules trapped in the mucus.
4. Yourolfactory receptor cells will no longer be able to synapse
within aglomerulus.

Answer 1

1. You will be unable to smell

3. Your olfactory receptor cells will no longer be able to respond to molecules trapped in the mucus.

Step-by-step explanation:

The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.

The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.

If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.

Thus, Options-1 and 3 are correct.
