Forms the anatomical bases for head & neck development Related to gill (brachial system) & located near the developing pharynx (pharyngeal) of the embryo. The branchial apparatus consists of: Branchial (pharyngeal) arches mesoderm Branchial (pharyngeal) clefts ectoderm Pharyngeal pouches endoderm Simultaneous with the development of the arches & clefts a number of outpocketings arise in … Read more

Development of Nervous System

Development of Nervous System

Prenatal Development of Central Nervous System At the beginning of the 3rd week, developing notochord induces overlying ectoderm to become neuroectoderm. Thus forming an elongated, slipper-shaped plate of thickened ectoderm – the neural plate. Neural plate invaginates and forms neural tube Pre-requirement for folding Notochord Anterior part Forms Forebrain Midbrain Hindbrain This neural plate invaginates, … Read more
