Salivary gland anatomy
ByStuart Winter, Brian Fish
Pages 6

Embryogenesis and ultrastructure The salivary glands share a common embryological development, whether they are the major named glands or the minor mucosal salivary glands.

The major salivary glands develop from the 6th to 8th weeks of gestation as outpouchings of oral ectoderm into the surrounding mesenchyme. The parotid develops first, growing in a posterior direction as the facial nerve advances anteriorly so that eventually, the parotid gland surrounds the facial nerve.
