The secretory senescence of the senses of smell and taste
Aging is a progressive and multifaceted event, which involves all the cells and organs of the human body. In this chapter we will try to analyze how the senses of smell and taste change with age. Anatomical and physiological modifications of the nose and salivary glands will be described, as well as changes in structures of the Central Nervous System and neurochemical processes that underlie these two senses. Finally, we will discuss the effect of many senile age drugs and chemo- radiotherapy on the perception of smell and taste, as well as the impact of chronical diseases on these senses.
