Question

i. When you smell tasty food your mouth waters which part of the
nervous system makes this happen?​

Answer 1

The nerves that control saliva production are part of a reflex system. They fire without conscious thought and can be activated by smells, tastes and even the movement of jaw muscles. When food is smelt, seen or even thought about, a signal is sent to your brain's primary salivary centres in the medulla oblongata.
