The hypothalamus secretes somatostatin, an inhibitory hormone.
It is a peptide hormone that influences neurotransmission and cell proliferation and controls the endocrine system.
The function of somatostatin:
Somatostatin, commonly known as growth hormone-inhibiting hormone, prevents the pituitary gland from secreting GH.
Somatostatin is generated in a variety of additional places, including the gastrointestinal (GI) tract, the pancreas, and the central nervous system (CNS).
Somatostatin has primarily neuroendocrine inhibitory effects in a variety of systems.
It has been shown to suppress GI, endocrine, exocrine, pancreatic, and pituitary secretions, as well as affect neurotransmission and memory formation in the central nervous system.
