Head Development

Introduction

The head and neck structures are derived from pharyngeal arches 1 - 6 with the face forming from arch 1 and 2 and the frontonasal prominence. Each arch contains similar Arch components derived from endoderm, mesoderm, neural crest and ectoderm. These components though will form different structures depending on their arch origin. Because the head contains many different structures also review notes on Special Senses ([senses.htm eye, ear, nose]), Respiratation ([respire.htm pharynx]), Integumentary ([skin10.htm Teeth]), Endocrine ([endocrine.htm thyroid, pituitary]).

Lecture Objectives

List the main structures derived from the pharyngeal arches, pouches and clefts.
Briefly summarise the development of teeth (primary and permanent)
Briefly summarise the development of the tongue.
Know the stages and structures involved in the development of the face.
Predict the results of abnormal development of the face and palate.

The Pharynx

The cavity within the pharyngeal arches forms the pharynx.

The pharynx contributes to 2 endocrine organs, in the roof the [endocrine7.htm 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 [head6.htm tongue].
