Arch	Nerve	Muscles	Skeletal	Artery
1 (maxillary/mandibular)	trigeminal (V)	mastication (temporalis, masseter, medial pterygoid, lateral pterygoid)	Meckel's cartilage mandible modelmalleus, incus	maxillary(terminal branches)
2 (hyoid)	facial (VII)	facial expression (buccinator, platysma, stapedius, stylohyoid, digastric posterior belly)	Reichert's cartilage stapes, styloid process, lesser cornu of hyoid, upper part of body of hyoid bone	stapedial (embryonic) corticotympanic (adult)
3	glossopharyngeal (IX)	stylopharyngeus	greater cornu of hyoid, lower part of body of hyoid bone	common carotid, internal carotid (root)
4 and 6	superior laryngeal and recurrent laryngeal branch of vagus (X)	intrinsic muscles of larynx, pharynx; levator palati	thyroid, cricoid, arytenoid, corniculate and cuneform cartilages	4 - aortic arch, right subclavian 6 - ductus arteriosus, pulmonary (roots)

Structures derived from Pouches

Pouch	Overall Structure	Specific Structures
1	tubotympanic recess	tympanic membrane, tympanic cavity, mastoid antrum, auditory tube
2	intratonsillar cleft	crypts of palatine tonsil, lymphatic nodules of palatine tonsil
3	inferior parathyroid gland, thymus gland
4	superior parathyroid gland, ultimobranchial body
5	becomes part of 4th pouch
