Question
Chapter 15.2, Problem 8AYP
Summary Introduction
To analyze:
The initiation of the action potential and the cells that it encounters on its way to the taste area of the cerebral cortex.
Introduction:
Taste hairs are the several hair-like structures present on the taste cell. These taste hairs extend to the opening called taste pores. These taste cells are replaced in the same way as the olfactory cells. The depolarization occurs by the binding of the tastants to the taste hair followed by the sensation of different tastes differently.

From a biological perspective, how do we experience taste? Discuss the composite of the five basic taste sensations. Include a relevant example. Please include references.
Describe the pathway of taste reception from the point where food comes into contact with the tongue to the point at which taste information travels to the brain. Briefly describe the structure and function of each organ along the pathway.
Taste cells form chemical synapses with afferent neurites that make up the gustatory
cranial nerve. For signals to pass onto the afferents, what critical step must take
place?
Opening of Ca++ channels
Opening of K+ channels
Opening of Na+ channels
Generation of an action potential
