Book Description
It develops from the endoderm of the oor of the pharynx with some contribution from the lateral pharyngeal pouches. Descent of the midline thyroid precursor gives rise to the thyroglossal duct, which extends from the foramen caecum near the base of the tongue to the isthmus of the thyroid. During development, the posterior aspect of the thyroid becomes associated with the parathyroid glands and the parafollicular C cells, derived from the ultimo-branchial body (fourth pharyngeal pouch), which become incorporated into its substance. The C cells are the source of calcitonin and give rise to medullary thyroid carcinoma when they undergo malignant transformation. The fetal thyroid begins to concentrate and organify iodine at about 10–12 weeks' gestation. Maternal TRH readily crosses the placenta; maternal TSH and T4 Do not. T4 from the fetal thyroid is the major thyroid hormone available to the fetus. The fetal pituitary-thyroid axis is a functional unit, distinct from that of the mother—active at 18–20weeks.
