The taste bud in the right side of the top of the fungiform papilla illus-trated in Figure 1 shows cellular relationships of the taste bud. The large peripheral lightly stained cells are the supporting cells of the bud, and the long inner darkly stained ones are the gustatory cells. The outer and inner taste pores are both distinguishable. Fig. 2.
Pharyngeal Arch Deficiencies Affect Taste Bud Development in the ...
During tongue development, peripheral sensory nerve innerva-tion occurs concomitantly from the cranial sensory ganglia through each PA, with the nerves penetrating into the tongue mesenchyme and reaching the tongue surface epithelium by E14.5 (Krimm 2007; Ma et al., 2009). The continuous differentia-tion and maintenance of taste buds is largely ...

taste bud is an active process, such that nerve fibers, which fail to seek out new taste receptor cells to inner-vate, will ultimately be lost. Given this plasticity, some ... the tongue is innervated and contain taste bud progenitor cells (Paulson et al., 1985; Thirumangalathu et al., 2009).

Biology of taste buds and the clinical problem of taste loss
Taste buds are the anatomical structures that mediate the sense of taste. They comprise taste cells and nerve fibers within specialized epithelial structures. Taste cells are traditionally described by histologic methods as basal, dark, intermediate, and light cells, with the nerve fibers surrounding and infiltrating the taste buds. By means of

and ion channels to the taste zones of the brain through the seventh, ninth and tenth cranial nerves. On average, the human tongue has 2,000-10,000 taste buds.[2] Their average lifespan is estimated at 10 days.[3] Types of papillae The taste buds on the tongue sit on raised protrusions of the surface of the tongue called papillae.

The areas of the tongue with the most taste buds are the tip of the tongue and the sides of the tongue though there are some taste buds scattered all over the tongue. Food is rough and wears out taste bud cells quickly. They are replaced about every 7-10 days. The “taste signal” is sent up a nerve fiber to the brain that tells us if we like ...

sides of the rear of the tongue. Taste buds are onion-shaped struc-tures of between 50 and 100 taste cells, each of which has fingerlike projections called microvilli that poke through an opening at the top of the taste bud called the taste pore. Chemicals from food termed tastants dissolve in saliva and contact the taste cells through the ...

Individual taste buds themselves respond to multiple tastes, but usually one of the tastes (such as salty) is perceived the strongest by a single taste bud.
