Morphological study of the parotid duct in human fetuses with special emphasis on the relationship between the buccinator muscle and the parotid duct

Abstract

, were prepared. They consisted of the following ages : three five-month-old fetuses, seven sixmonth-old fetuses, six seven-month-old fetuses, eight nine-month-old fetuses, and six ten-month-old fetuses. Their ages were determined by measuring their body lengths. These specimens were perfused with 10% formaldehyde fixative. After removing the facial skin, each parotid duct from the entrance of the buccinator muscle to the opening of the oral cavity along with its surrounding buccinator muscle was removed en bloc (Fig. 1).Twenty specimens were cut open from the entrance of the buccinator muscle toward the opening of the oral cavity under a dissection light microscope for morphological examination prior to scanning electron microscope (SEM) observation. After conductive staining with tannin-osmium (1%) solution, we dehydrated them with alcohol and used the tbutyl alcohol freeze drying method for preparing MINI REVIEWMorphological study of the parotid duct in human fetuses with special emphasis on the relationship between the buccinator muscle and the parotid duct

Atrial Natriuretic Peptide presence in parotid gland of human fetus at 13th week of development and in adult man

“…The morphology of developing salivary glands was described in rat [20,21], mouse [22], miniature pig [23], and in humans [24]. Few reports referred to the presence of peptides in the developing parotid gland.…”
