Explanation Explanation for the correct answer: Option (b) is hypoglossal nerve. This nerve does not participate in the gustatory sensation. The ends of gustatory cells (basal end) create synapse with the receptive endings of the sensory neurons which transfer stimuli of taste into the CNS (central nervous system) with the help of glossopharyngeal (CN IX), facial (CN VII) and vagus nerves (CN X). Hence, option (b) is correct. Explanation for the incorrect answers: Option (a) is vagus (X). Thevagus nerve plays a little role in the gustation as it innervates the taste buds that are scattered at the base of the tongue...

Summary Introduction

Introduction:

The gustation stimulation involves chemoreceptors that respond to a chemical stimulus. Specialized receptor cells called taste buds are responsible for taste. The tongue also consists of the papillae which are of four types. Taste buds contain three types of cells; gustatory cells, supporting cells and basal cells.
