Which of the following hormones released from the pituitary is actually synthesized in the hypothalamus?
- Follicle-stimulating hormone (FSH)
- Adrenocorticotropic hormone (ACTH)
- Luteinizing hormone (LH)
- Anti-diuretic hormone (ADH)
Answer
(4) Anti-diuretic hormone (ADH)
Solution
FSH, ACTH and LH are synthesised and secreted by the adenohypophysis.
The neurohypophysis (posterior pituitary) only stores and releases oxytocin and vasopressin (ADH); these hormones are actually synthesised by the neurosecretory cells of the hypothalamus and carried along their axons to the neurohypophysis.
Answer: (4)
