Select the correct statement about oxytocin.

Oxytocin is a peptide hormone (nine amino acids) synthesised by the hypothalamus. 

It is transported to the neurohypophysis through the hypothalamo-hypophyseal tract. Neurohypophysis does not synthesise but stores it and releases it into the blood through which it reaches its target organs. 

Oxytocin stimulates milk ejection but not milk secretion. Oxytocin stimulates the contraction of smooth muscles (e.g., uterus) and myoepithelial cells (e.g., mammary glands) but not skeletal muscles.
