The hormones produced in the hypothalamus are

Step 1: Analyze the question You are asked which pair of hormones is produced in the hypothalamus, the part of the brain just above the pituitary gland.

Step 2: The concept The hypothalamus links the nervous system to the endocrine system. It makes:

• Releasing and inhibiting hormones, such as TRH, GnRH, CRH and somatostatin, which control the anterior pituitary.
• Oxytocin and vasopressin (ADH), which are made in hypothalamic neurons. They travel down nerve fibres to the posterior pituitary, where they are stored and released.

Many textbooks wrongly say the posterior pituitary "produces" these two hormones. It only stores and releases them.

Step 3: Check each option

• A. Auxin and somatotropin: Auxin is a plant hormone. Somatotropin (growth hormone) comes from the anterior pituitary. ✗
• B. Oxytocin and vasopressin: Both are made in the hypothalamus. ✓
• C. Parathormone and progesterone: Parathormone comes from the parathyroid glands. Progesterone comes from the ovaries (corpus luteum) and the placenta. ✗
• D. Testosterone and insulin: Testosterone comes from the testes. Insulin comes from the pancreas. ✗
• E. Thyroxine and nor-adrenalin: Thyroxine comes from the thyroid. Noradrenaline comes from the adrenal medulla. ✗

Step 4: Answer The correct option is B, oxytocin and vasopressin.

Tip: Remember "Oxytocin and Vasopressin are Out of the Very top of the brain (hypothalamus)." Also remember that the hypothalamus makes them and the posterior pituitary only releases them. NECO and JAMB often test this.
