Time course of morphological alterations of fungiform papillae and taste buds following chorda tympani transection in neonatal rats.
The time course of structural changes in fungiform papillae was analyzed in rats that received unilateral chorda tympani nerve transection at 10 days of age. Morphological differences between intact and denervated sides of the tongue were first observed at 8 days postsection, with an increase in the number of fungiform papillae that did not have a pore. In addition, the first papilla with a fil...
متن کاملFungiform taste bud degeneration in C57BL/6J mice following chorda-lingual nerve transection.
Taste buds are dependent on innervation for normal morphology and function. Fungiform taste bud degeneration after chorda tympani nerve injury has been well documented in rats, hamsters, and gerbils. The current study examines fungiform taste bud distribution and structure in adult C57BL/6J mice from both intact taste systems and after unilateral chorda-lingual nerve transection. Fungiform tast...
متن کاملNeural control of ectopic filiform spines in adult tongue.
The tongue surface directly above a fungiform taste bud is flat, thinly keratinized, and free of filiform spines. We examined fungiform papillae in serial sections of rat and gerbil tongues after unilateral transection of the chorda-lingual nerve had caused many fungiform taste buds to degenerate. Such empty fungiform papillae often formed a solitary keratinized outgrowth that closely resembled...
متن کاملMorphometric and immunocytochemical assessment of fungiform taste buds after interruption of the chorda-lingual nerve.
Unilateral interruption of the chorda-lingual nerve led to a loss of most epithelial axons and to the deterioration of fungiform taste buds in the anterior portion of the tongue of albino rats, mongolian gerbils, and golden hamsters. By three weeks after surgery the following percentages of fungiform taste buds had completely disappeared: 71% in gerbils, 28% in rats, and 26% in hamsters. Residu...
متن کاملChanges in fungiform papillae density during development in humans.
The anterior region of the human tongue ceases to grow by 8-10 years of age and the posterior region at 15-16 years. This study was conducted with 30 adults and 85 children (7-12 year olds) to determine whether the cessation of growth in the anterior tongue coincides with the stabilization of the number and distribution of fungiform papillae (FP) on this region of the tongue. This is important ...
