Question

Quizplus · Accepted Answer

Cleft lip is caused by the incomplete fusion of the nasomedial or intermaxillary process beginning the fourth week of embryonic development,a period of rapid development.
Cleft lip,not nasal passage atresia,occurs when there is lack of or incomplete fusion of the nasomedial or intermaxillary process.
In esophageal atresia,the esophagus ends in a blind pouch.It is not associated with nasomedial processes.
Lack of dentition is not due to incomplete fusion of the processes.
