Quizplus · Accepted Answer

During the fourth week of prenatal development,within the embryonic period,an adjacent swelling forms from increased growth of the mandibular arch on each side of the stomodeum,the maxillary process.In the future,the lateral nasal processes form the alae of the nose,and the fusion of the lateral nasal,maxillary,and medial nasal processes forms the nares.The paired medial nasal processes also fuse internally and grow inferiorly on the inside of the stomodeum,forming the intermaxillary segment by the end of the seventh week of prenatal development.In the future,the medial nasal processes will fuse together externally to form the middle part of the nose from the root of the nose to the apex of the nose,as well as the tubercle of the upper lip and philtrum.
