[21] Afferent nerves make contact with the receptor cells at the base of the taste bud. [23] A single taste bud is innervated by several afferent nerves, while a single efferent fiber innervates several taste ...
The taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of lingual papillae; all except one contain taste buds: Fungiform papillae - as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section.

Anosmia is the inability to perceive odor, or in other words a lack of functioning olfaction.Many patients may experience unilateral or bilateral anosmia. A temporary loss of smell can be caused by a blocked nose or infection. In contrast, a permanent loss of smell may be caused by death of olfactory receptor neurons in the nose or by brain injury in which there is damage to the
