What are Neurohormones? How do these Neurohormones reach the pituitary glands? The hypothalamus is located inferior to the thalamus of the brain and it secretes neurohormones. Neurohormones are secreted by neurosecretory cells located within supraoptic and paraventricular nuclei of the hypothalamus. These hormones influence the activity of pituitary glands. These neurohormones secreted by the hypothalamus are connected to the pituitary gland by hypophyseal portal vessels. The neurohormones from the hypothalamus reach to the anterior pituitary gland through the portal vein blood after passing through the stalk. These neurohormones control the secretion of hormones by the cells of the pituitary gland. … Continue reading Neurohormones
