About this document
Second Pharyngeal Pouch Overview by djae57262 is a document available to read on EtoBox.
The pharyngeal apparatus in a four-week human embryo consists of pharyngeal arches, pouches, grooves, and membranes, resembling fish embryos. The arches contribute to the development of facial structures, while the pouches give rise to various glands and tissues, such as the thymus and parathyroid glands. Developmental anomalies can occur due to insufficient migration of neural crest cells, leading to conditions like Treacher Collins syndrome and DiGeorge syndrome.
