Neural tube defects
What type of twins?
Monozygotic twins
Dizygotic twins/fraternal twins
Pharyngeal arches
Third arch derivatives
The first pharyngeal cleft : develops into the external auditory meatus (the corresponding 1st pharyngeal pouch develops into the auditory (or Eustacian) tube, and the intervening membrane develops into the tympanic membrane).
• The pharyngeal clefts 2, 3, and 4 are overgrown by expansion of the 2nd pharyngeal arch and usually obliterated.
• Remnants of pharyngeal clefts 2-4 can appear in the form of cervical cysts or fistulas found along the anterior border of the sternocleidomastoid muscle.
