Hypothalamic Hormones
Hypothalamic hormones regulate anterior pituitary function
Hypothalamic Hormones:
- Releasing hormones :TRH – stimulates TSH & prolactin
- GnRH – stimulates LH & FSH
- Inhibitory hormones :Somatostatin – inhibits GH & TSH
- Dopamine – inhibits prolactin

What our notes say
- Hypothalamic hormones regulate anterior pituitary function (Medical Physiology Paper II MCQs)
- Target organ hormones directly inhibit hypothalamic hormone release (Medical Physiology Paper II MCQs)
- Hypothalamic Hormone Release:The hypothalamus secretes releasing or inhibiting hormones that influence the anterior pituitary's activity. (LECTURE 6: Pancreatic and Adrenal Hormones)
- Hypothalamic Hormones: Master Regulators of the Endocrine System (Hypothalamic Hormones: Master Regulators of the Endocrine System)
- Hypothalamic Hormone Action: Hypothalamic neurons synthesize and release specific hormones that either stimulate or inhibit the secretion of anterior pituitary hormones. (Hypothalamic Hormones: Master Regulators of the Endocrine System)
- Hypothalamic Hormones: These include releasing and inhibiting hormones (e.g., TRH, CRH) that regulate pituitary function. (LECTURE 1: Principles of Endocrinology)

Practice questions on Hypothalamic Hormones
The hypothalamic hormone that stimulates both FSH and LH release is
- TRH
- Somatostatin
- CRH
- GnRH
Answer: D. GnRH is released in pulses from the hypothalamus, stimulating pituitary gonadotrophs to secrete both FSH and LH. ---
