19. Embryology (Endocrine System): Messages Without Wires
The endocrine system develops quietly, without ducts or obvious boundaries, yet its influence is global. This episode explores how dispersed endocrine organs arise from multiple embryological origins and come to regulate growth, metabolism, and internal balance across the body.
Drawing on IB Singh’s clear sequencing, we trace the embryological origins of key endocrine organs — including the thyroid, parathyroids, adrenal glands, pancreas, pituitary, and gonads. Particular attention is given to migration, interaction, and timing, which explain why endocrine anatomy is so closely linked to…
