Its follicular cells secrete tyrosine derivatives, its parafollicular cells secrete calcitonin, which is opposed by PTH produced by four glands embedded in its surface.
Two of its products play a role in fetal brain maturation, and OATP1C1 and MTC8 have been implicated in their transport across the blood-brain barrier. In humans, this organ is on the same plane as the cricoid cartilage, and its namesake superior artery emerges from a point above the origin of the ascending pharyngeal, lingual, and facial arteries. Its follicular cells secrete tyrosine derivatives, its parafollicular cells secrete calcitonin, which is opposed by PTH produced by four glands embedded in its surface. Triiodothyronine and thyroxine, or T3 and T4, are the primary products of, for 10 points, this butterfly-shaped organ, which may develop a goitre because of iodine deficiency.
