Question

2) which one is the right flow chart? ( particles dissolve in saliva - Brain chemoreceptors- Nerve - Brain ) (particles dissolve in mucus -olfactory receptors -NerveBrain) (oval window - Nerve car ossicles- hair cells inside cochlea - Brain )​

Answer 1

Answer:

• particles dissolve in saliva
• brain chemoreceptors- nerve brain

Answer 2

The correct pathway will be saliva → chemoreceptors→ Nerve → Brain.

• First, the food that we eat dissolves in the saliva. The saliva has salivary amylase which helps in the digestion of 30% starch in the mouth with an enzyme salivary amylase.

• The chemoreceptors are present in the taste buds on the tongue. The chemoreceptor for taste is called gustatory receptor. These chemoreceptors convert the external stimuli or rather signal such as taste into intracellular messages.

• These messages travel all the way through nerves to the brain which further detects the taste.
