[Epthelial derivates of the transversal groove of the stomodeum: parotid gland and juxtaoral organ].
A study was carried out in humans on the initial developmental stages of structures derived from the epithelial transversal groove of the primitive mouth. In O'Rahilly's stage 16, an epithelial condensation can be observed, the anlage of Chievitz's organ, while the anlage of the parotid gland was observed in O'Rahilly's stage 18. These structures are defined by their relationships with the mesenchyme and with their topographical location.
