Nettet8. aug. 2024 · The first sign of development of taste bud on the lingual epithelium occurs at the 8th week of gestation. Between the ninth and eleventh week of gestation, many taste bud primordia develop. They differentiate into different cell types around the eleventh through the thirteenth postovulatory week. During this period, taste pores also develop. Nettet28. jan. 2016 · Lingual dorsal epithelium contains four kinds of papillae: filiform, fungiform, foliate, and circumvallate papillae. Stratum corneum is seen in filiform papillae, but not in fungiform, foliate, or circumvallate papillae. In contrast, taste buds are seen in fungiform, foliate, and circumvallate papillae but not in filiform papillae.
