Answer 1

Answer:

a). TRH stands for Thyrotropin-releasing hormone. It is secreted by the neurons in the hypothalamus.

b). TSH stands for Thyroid-stimulating hormone. It is secreted by the anterior  pituitary which are known as thyrotrophs.

c). Thyroxine is the main hormone which is secreted into the blood by the thyroid glands.
