Growth hormone–releasing hormone (GHRH), also known as somatocrinin among other names in its endogenous form and as somatorelin in its pharmaceutical form, is a releasing hormone of growth hormone (GH). It is a 44 [1]-amino acid peptide hormone produced in the arcuate nucleus of the hypothalamus.
The hypothalamic–pituitary–somatotropic axis (HPS axis), or hypothalamic–pituitary–somatic axis, also known as the hypothalamic–pituitary–growth axis, is a hypothalamic–pituitary axis which includes the secretion of growth hormone (GH; somatotropin) from the somatotropes of the pituitary gland into the circulation and the subsequent stimulation of insulin-like growth factor 1 ...

The hypothalamus uses gonadotropin-releasing hormone (GnRH or gonadoliberin) to tell the pituitary to release gonadotropin. The hypothalamus uses growth hormone–releasing hormone (GHRH or somatoliberin) to tell the pituitary to release somatotropin. The main release-inhibiting hormones or inhibiting hormones are as follows:
The hypothalamus is divided into four regions (preoptic, supraoptic, tuberal, mammillary) in a parasagittal plane, indicating location anterior-posterior; and three zones (periventricular, intermediate, lateral) in the coronal plane, indicating location medial-lateral. [7] Hypothalamic nuclei are located within these specific regions and zones. [8]
These neurons, generated from the ventral part of the periventricular epithelium during embryonic development, locate dorsally in the hypothalamus, becoming part of the ventromedial hypothalamic region. [3] [2] [4] The function of the arcuate nucleus relies on its diversity of neurons, but its central role is involved in homeostasis. The ...
Secretion of growth hormone (GH) in the pituitary is regulated by the neurosecretory nuclei of the hypothalamus. These cells release the peptides growth hormone-releasing hormone (GHRH or somatocrinin) and growth hormone-inhibiting hormone (GHIH or somatostatin) into the hypophyseal portal venous blood surrounding the pituitary. GH release in ...
The median eminence contains fiber terminals from many hypothalamic neuroendocrine neurons, secreting different neurotransmitters or neuropeptides, including vasopressin, corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone (TRH), gonadotropin-releasing hormone (GnRH), growth hormone-releasing hormone (GHRH), dopamine (DA) and ...
