D. Which division of the autonomic nervous system does smelling lemon juice (or other citrus juices) stimulate the production of watery saliva?
E. What phase of the digestive process does this stimulate?
F. What is the cranial nerve that serves as a channel for the parasympathetic neurones that innervate the heart?
