[Histo-ontogenetic study of the major salivary glands and Chievitz's organ]

Salivary glands development has been studied by optical microscopy in 8 fetuses aged from 8 to 20 weeks of fetal life. From the observation of the sections obtained we can assume that submandibular gland is the first gland to be detectable, later the parotid gland and then the sublingual gland. In tight connection with the parotid gland Chievitz organ has been demonstrated. It is not known whether this organ may or may not contribute to parotid gland.
