A neuropeptide and nonapeptide hormone synthesized primarily in the paraventricular and supraoptic nuclei of the hypothalamus and released by the posterior pituitary gland. Clinically recognized for its critical roles in parturition and lactation, oxytocin also functions as a neuromodulator in the brain, influencing social bonding, trust, and anxiety. Its widespread effects highlight its importance in the intersection of endocrine and behavioral health. This hormone is often referred to informally as the “love hormone” due to its pro-social effects.
Origin
The term is rooted in Greek, combining oxýs (sharp/quick) and tókos (birth), referencing its original clinical discovery as a facilitator of uterine contractions during labor. It is a fundamental component of the neuroendocrine system, linking the central nervous system with peripheral endocrine function.
Mechanism
Oxytocin exerts its effects by binding to specific G protein-coupled receptors (OXTR) located on myoepithelial cells in the mammary glands, uterine smooth muscle cells, and various regions of the central nervous system. In the uterus, it promotes powerful contractions, while in the brain, its action modulates neural circuits involved in stress response and social recognition, thereby influencing emotional regulation and behavior. Its signaling is crucial for reproductive and social physiology.
