Please add:
abnormal second branchial pouch morphology
DEF: any structural anomaly of the second branchial pouch located between the second and third branchial arches; the dorsal elongation of the second pouch endoderm of all mammals, with the exception of rodents, gives rise to the epithelial lining of palatine tonsils; in rodents, the ventral portion of the second pouch appears to degenerate whereas the remaining part is incorporated into the lateral border of the pharynx; it appears that rodents no longer require tonsils as their function is carried out by the NALT (Nose/Nasal-Associated Lymphoid Tissue) system in the upper respiratory tract
SYN: abnormal 2nd branchial pouch morphology
SYN: abnormal 2nd pharyngeal pouch morphology
SYN: abnormal second pharyngeal pouch morphology

absent second branchial pouch
DEF: absence of the second branchial pouch, normally located between the second and third branchial arches; the dorsal elongation of the second pouch endoderm of all mammals, with the exception of rodents, gives rise to the epithelial lining of palatine tonsils
