Epidermis of skin Function of stratified epithelium is secretion protection absorption both a & c are correct Transitional epithelium is stretchable as it has Thick basement membrane wide intracellular substance containing mucous like substance thin layer of keratin on top layer flat cells in the top layer and columnar cells in the top layer The type of epithelium that can accommodate stretch is stratified squamous epithelium Transitional epithelium stratified columnar epithelium According to the mode of secretion the exocrine glands classified into Apocrine, holocrine and merocrine glands Mucous, serous and mucoserous glands Simple, branched, and compound glands Alveolar, tubular and tubuloalveolar glands Mixed gland is a mixture of Endocrine and exocrine glands Simple and compound glands Unicellular and multicellular glands Stroma and parenchyma salivary glands release their secretion by merocrine apocrine holocrine The function of transitional epithelium is stretchability Distensibility Protection from toxins All of the above 1 out of 15 Time's up
