Embryonic taste buds develop in the absence of innervation.
It has been hypothesized that taste buds are induced by contact with developing cranial nerve fibers late in embryonic development, since descriptive studies indicate that during embryonic development taste cell differentiation occurs concomitantly with or slightly following the advent of innervation. However, experimental evidence delineating the role of innervation in taste bud development is...
متن کاملTaste isn't just for taste buds anymore
Taste is a discriminative sense involving specialized receptor cells of the oral cavity (taste buds) and at least two distinct families of G protein-coupled receptor molecules that detect nutritionally important substances or potential toxins. Yet the receptor mechanisms that drive taste also are utilized by numerous systems throughout the body. How and why these so-called taste receptors are u...
متن کاملCellular mechanisms in taste buds.
In the soft palate, tongue, pharynx and larynx surrounding the oral region, taste buds are present, allowing the sensation of taste. On the tongue surface, 3 kinds of papillae are present: fungiform, foliate, and circumvallate. Approximately 5,000 taste buds cover the surface of the human tongue, with about 30% fungiform, 30% foliate and 40% circumvallate papillae. Each taste bud comprises 4 ki...
متن کاملDiscrete innervation of murine taste buds by peripheral taste neurons.
The peripheral taste system likely maintains a specific relationship between ganglion cells that signal a particular taste quality and taste bud cells responsive to that quality. We have explored a measure of the receptoneural relationship in the mouse. By injecting single fungiform taste buds with lipophilic retrograde neuroanatomical markers, the number of labeled geniculate ganglion cells in...
متن کاملTaste Preference Following Cross-Innervation of Rat Fungiform Taste Buds'
OAKLEY, B. Taste preference following cross-innervation of rat fungiform taste buds. PHYSIOL. BEHAV. 4 (6) 929--933, 1969.-It has been previously demonstrated that cross-innervation of rat taste buds alters some features of the taste input signal to the brain. In the present study the behavioral consequences of these alterations were assessed in a choice situation in which both water and taste ...
