Concerning the development of the respiratory system:

[Medicoman]

1 The lateral palatine processes:

• 1 Are derived from the maxillary prominences
• 2 Encounter the tongue and grow vertically downward
• 3 Elevate and fuse slightly later in female embryos
• 4 Normally complete their fusion in the embryonic period

2 Concerning the development of the respiratory
system:

• 1 The nasal and oral cavities initially communicate just
• posterior to the primary palate
• 2 Except for the epiglottis, the laryngeal cartilages are
• derived from the pharyngeal arch cartilages
• 3 The laryngotracheal diverticulum is a foregut
• derivative
• 4 The developing lungs grow into the medial aspects of
• the pleural canals

3 With reference to the developing face:

• 1 The nasal placodes are thickenings of surface
• ectoderm on the inferior aspect of the frontonasal
• prominence
• 2 The nasolacrimal duct will develop along the
• groove separating the medial and lateral nasal
• prominences
• 3 Much of the mesenchyme of the facial region is
• considered to be of neural crest origin
• 4 The muscles of facial expression are derived from the
• first pharyngeal arches

4 Gartner’s cysts are embryological remnants of the:

• 1 Ureteric diverticulum
• 2 Sinovaginal bulb
• 3 Paramesonephric duct
• 4 Mesonephric duct

5 The labioscrotal folds in the embryo give rise to the:

• 1 Clitoris
• 2 Labia minora
• 3 Round ligament of the uterus
• 4 Labia majora
