Glandular Epithelial Flashcards
Classification of glands based on their number of cells is divided into
Unicellular gland &
Multicellular gland
Multicellular glands are divided into?
Simple - one unbranched duct eg sweat gland
Compound - branched ducts eg parotid gland
Two characteristics of unicellular glands are?
Scattered among other non secretory epithelial cells
They have no ducts
The only unicellular gland in mammals are?
Goblet cells
Goblet cells secrete the glycoprotein______ which is converted into_____ by the uptake of water
Mucin, mucous
Goblet cells are scattered among the absorptive cells in the epithelium of
Small intestine, colon, respiratory tract and female reproductive female tract
Goblet cells are found in____ epithelium and ____ epithelium
Simple columnar, pseudostratified columnar
Multicellular glands can be divided into?
Intraepithelial gland: within the epithelium
Extraepithelial gland: below the epithelium
Exocrine gland types according to shape are divided into?
Simple tubular Simple coiled tubular Simple branched tubular Simple branched acinar Compound tubuloacinar Compound tubular Compound acinar
The mode of secretion that doesn’t affect the well being of the cell is?
Merocrine: sweat glands, salivary glands, pancreas, lacimal gland etc
The mode of secretion in which part of the cell cytoplasm is lost with the secretion is?
Apocrine: mammary glands
The mode of secretion in which a great deal of cytoplasm is lost with the secretion or the cell dies is?
Holocrine: sebaceous glands
Four composition of secretum are?
Mucous
Serous
Sero-mucous
Lipid
Four characteristics of mucous gland are?
Well seen, wide lumen
Pale stained, foamy cytoplasm with H.E
Viscous secretory product
Basally located nuclei
Four characteristics of serous glands are?
Centrally located nucleus
Basophil cytoplasm
Narrow lumen
Protein-rich fluidly secretum
