Oxytocin Release

Meaning

Oxytocin release is the process of secreting the nine-amino-acid peptide hormone, Oxytocin, from the nerve endings in the posterior pituitary gland into the systemic circulation, or locally within the brain. This release is characteristically pulsatile and is triggered by specific physiological and social stimuli. Peripheral release is critical for functions such as uterine contractions during childbirth and milk ejection during lactation. Central release, however, is a key component of neuroendocrine signaling, profoundly influencing complex social behaviors, including bonding, trust, and the reduction of anxiety.
