Use dihydroergotamine exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor. Dihydroergotamine can damage the heart and other organs if it is used too often. Dihydroergotamine should be used only to treat a migraine that is in progress.
The posterior pituitary is often termed the neurohypophysis because the hormones of this part of the pituitary are released directly from the axonal endings of their source neurons into the circulation (Figure 2.1).
Pituitary Gland. The pituitary gland, or hypophysis, is about the size of a pea and sits in the small, bony cavity (sella turcica) at the base of the brain. The pituitary gland is divided into two sections: the anterior lobe (adenohypophysis) and the posterior lobe (neurohypophysis).The posterior pituitary is, in effect, a projection of the hypothalamus.It does not produce its own hormones, but only stores and releases the hormones created by the hypothalamus, whereas the anterior pituitary produces and secretes its own hormones.he posterior pituitary is, in effect, a projection of the hypothalamus.
