How does hypothalamus control both anterior and posterior pituitary functioning?
The posterior pituitary gland Nerves go directly from two nucleii in the hypothalamus (supraoptic & paraventricular) to the posterior pituitary Posterior pituitary hormones are made in the cell bodies of the nerves Hormones travel down the nerve axons by axoplasmic transport to the pituitary Hormones released from the pituitary as needed by neurosecretion The posterior pituitary releases two hormones ADH – acts on collecting duct of the kidney to increase water retention Oxytocin stimulates uterus to contract during childbirth Also causes vasoconstriction & raises blood pressure.
