Oxytocin

Meaning

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.
