Stage 13

B1: Dorsal portion of hypopharyngeal eminence. Rathke's pouch derived from ectoderm anterior to the buccopharyngeal membrane ( rudimentary adenohypophysis).

B2: Rathke's pouch. Thyroid rudiment (cords) arrowed dark spots near midline.

B3: Rudimentary thyroid ventral to aortic sac (also seen in B2, ventral to the hypopharyngeal eminence).

G7: (Close to midline in head region). Forebrain, midbrain, hindbrain (with thin roof). Arrowed Rathke's pouch. Floor of pharynx with foramen caecum (the tongue has not yet formed).

Stage 22

List of serial section images containing endocrine components.

A6: Thalamus/hypothalamus.

B2: Neurohyophysis and adenohypophysis. Remnant of Rathke's pouch (residual lumen) in adenohypophysis.

B3: Adenohypophysis.

C3: Glottic region with cricoid cartilage and descending process of thyroid cartilage laterally.

C4: Section damaged, but shows thyroid gland lateral to trachea.

C5: Thyroidgland.

Dl: Thymus gland.

E6: R,L adrenal glands under diaphragm.

E7: Large adrenal glands.

Fl: Adrenal glands. R. Kidney. Autonomic ganglia (partly the adrenal medulla precursors).

F2: Kidneys (note retroperitoneal location). Cortex. Medulla. L. Adrenal gland.
