Salivary glands contain what three major cell types? | acinar cells ductal cells, myoepithelial cells |
Three main types of acini are? | serous mucinous seromucous |
When the gland has this demilunar structure, it produces? | both serous and mucous secretions, and is thus classified as "mixed". |
Demilune cells secrete? | the proteins that contain the enzyme lysozyme, which degrades the cell walls of bacteria. In this way, lysozyme confers antimicrobial activity to mucus. |
Which tissue contains the nerves and blood supply supporting each gland? | The capsule and the septa |
What is the lumen? | central opening where the saliva is deposited after being produced by the secretory cells |
Merocrine Secretion is | |
Characteristics of serous acini | serous cells with clear cytoplasm secrete more watery product primary source of amylase narrow lumen cells are pyramidal shape in cross section |
