Oxytocin is a hormone that acts on organs in the body and as a chemical messenger in the brain, controlling key aspects of the reproductive system, including childbirth and lactation, and aspects of human behaviour. Oxytocin is produced in the hypothalamus and is secreted into the bloodstream by the posterior pituitary gland. The posterior pituitary does not produce any hormones of its own, rather, it stores and secretes two hormones made in the hypothalamus— oxytocin and antidiuretic hormone. Oxytocin stimulates the uterine muscles to contract and also increases the production of prostaglandins, which increase the contractions further.

**Hormone secreted by the posterior lobe of the pituitary**
The hormone secreted by the posterior lobe of the pituitary gland that is concerned with the contraction of uterine muscles is called oxytocin. Oxytocin is a peptide hormone that plays a crucial role in various physiological processes in the body.
**Function of Oxytocin**
- **Contraction of uterine muscles**: Oxytocin is primarily known for its role in inducing uterine contractions during childbirth. It helps in the progression of labor and delivery by stimulating the contraction of uterine muscles.
- **Stimulation of milk ejection**: Oxytocin also plays a role in the ejection of milk from the mammary glands during breastfeeding. It causes the contraction of myoepithelial cells surrounding the alveoli in the breast, leading to the release of milk.
- **Social bonding and behavior**: Oxytocin is sometimes referred to as the "love hormone" or "bonding hormone" because it is involved in social bonding, trust, and emotional interactions. It promotes feelings of closeness and connection between individuals.
- **Regulation of stress and anxiety**: Oxytocin has been shown to have anxiolytic (anti-anxiety) effects and can help reduce stress levels in the body.
**Conclusion**
In conclusion, oxytocin is a hormone secreted by the posterior lobe of the pituitary gland that is primarily involved in the contraction of uterine muscles during childbirth and the ejection of milk during breastfeeding. It also plays a role in social bonding, stress regulation, and other physiological processes in the body.
