35
external auditory meatus
1st pharyngeal cleft
36
temporary cervical sinus
2-4 pharyngeal cleft
37
a pharyngeal (brachial cyst) is because the _____ fails to obliterate completely
2nd phayngeal cleft
38
medial swelling/ copula
2,3, anterior 4 arch
39
2 lateral swellings and 1 medial swelling

41
tympanic cavity (middle ear)
1st pharyngeal pouch
42
auditory tube (eustachian tube)
1st pharyngeal pouch
43
epithelial libing of palatine tonsils and tonsillar fossa
2nd pharyngeal pouch
44
inferior parathyroids
dorsal win 3rd pharyngeal pouch
45
thymus gland
ventral wing 3rd pharyngeal pouch
46
superior parathyroids
dorsal wings 4th pharyneal pouch
47
ultimobrachial body- parafollicular [c] cells of thyroid gland
ventral wing 4th pharyngeal pouch the cells themselves come from NCC
48
pt has insufficient migration of NCC into the 1st arch
treacher collins
49
pt presents with an overbite, retrusive chin & jaw, external ear abnormalities , maar hypoplasia
treacher collins
50
pt 1st arch structures are altered
pierre robins sequence
51
pt presents with hypoplasia of mandible, the tongue is drawn down, micrognathia, glossoptosis
pierre robins micrognathia- low jaw undersized glossoptosis- tongue too far back
52
pt has underdeveloped thymus, hypoparathyroidism, and congential heart defects
digeorge syndrome
53
migration errors of 3rd and 4th pouches- tissues end up in abnormal places
ectopic/ abberant parathyroid/thymic tissues
54
ectopic parathyroid
may end up in neck/chest- can cause persistent hypothyroidism if not removed
55
ectopic thymus
no symptoms- but can lead to mass in neck that compress trachea and esophagus
56
incomplete fusion of lateral lingual sweeling resulting in bifid tongue
glossoschissis
57
excessively large tongue caused by general hypertrophy
macroglossia
58
frenulum is short and extends to tip of tongue
ankyloglossia
59
thyroid gland
does not come from pharyngeal pouches
60
failure of thyroid primordium to migrate completely - accessory tissue is found along thryglossal duct
ectopic thyroid
61
thyroid gland has developed but fails to develop
sublingual thyroid gland
62
pt has a cyst in the tongue or anterior neck due to persistent duct
thryoglossal duct cyst
63
how to tell difference between thryoglossal duct cyst and ectopic thyroid
thyroglossal- has movement during swallowing and is in a midline position
64
absence of thyroid
agenesis
65
unilateral absence of thyroid; affects left lobe
hemiagenesis
66
pt has decrease in thyroid hormones, increase TSH levels, CNS development and lung development are affected
congential hypothyroidism
