A pair of salivary glands tucked into the notch in front of each ear and emptying through parotid ducts by each upper 2nd molar. Although the fluid has some of the thick viscous lubricant nature of saliva from the glands in the floor of the mouth, the parotids secrete high levels of ptyelin and amylase (starch-digesting enzymes) lysozymes (antimicrobial enzymes) and a group of proteins loosely called parotin that stimulate epithelial and nerve cell growth...a lot more here than just spit.
