🔬 Medical science
The thyroid regulates metabolism through the hormones T3 and T4, under pituitary TSH control. Conditions include autoimmune hypothyroidism (Hashimoto's) and hyperthyroidism (Graves'), nodules, and thyroid cancer; iodine status and radiation exposure are relevant factors.
Diagnosis relies on measurable hormone levels, autoantibodies and ultrasound; treatment uses hormone replacement, anti-thyroid drugs, radioiodine or surgery.
🧩 The GNM model
Claimed conflict: GNM links the thyroid gland to a conflict of "not being able to act fast enough" (needing to speed up), and the thyroid ducts to a conflict of "feeling powerless / not fast enough to escape."
Germ layer & brain relay (GNM model): GNM classes the thyroid acinar tissue as endoderm controlled from the brainstem and the thyroid ducts as ectoderm controlled from the cerebral cortex.
Two-phase course (claimed): GNM claims the glandular tissue proliferates during conflict activity (altering hormone output) and is reduced in healing, with duct portions ulcerating then swelling.
