Introduction
The head and neck are one of the most complicated structures that the embryo forms, with special intermediate structures (the pharyngeal arches) and contributions from all 3 embryonic layers (ectoderm, mesoderm, endoderm), and significantly, a major contribution from the neural crest.
The head and neck structures are mainly derived from pharyngeal arches 1 and 2. Each arch contains similar components derived from endoderm, mesoderm, neural crest and ectoderm. These components though will form different structures dependent upon which arch they are within. The cavity within the pharyngeal arches forms the pharynx.
The pharynx contributes to 2 endocrine organs, in the roof the pituitary (hypophysis) and the floor the thyroid. The thyroid gland being one of the first endocrine organs to be formed has an important role in embryonic development. The pharynx floor of all arches also contribute to the formation of the tongue.
Because the head contains many different structures also review notes on Special Senses (eye, ear, nose), Respiratation (pharynx), Integumentary (Teeth), Endocrine (thyroid, pituitary).
