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.
