Neuroendocrinology is regulated by afferent synaptic inputs from other brain regions. By contrast, the hormones of the anterior pituitary gland (the adenohypophysis) are secreted from endocrine cells that, in mammals, are not directly innervated, yet the secretion of these hormones (adrenocorticotrophic hormone, luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone, prolactin, and growth hormone) remains under the control of the hypothalamus. The hypothalamus controls the anterior pituitary gland via "releasing factors" and "release-inhibiting factors"; these are blood-borne substances [author means via bloodstream and not by the lymphatic system nor air, nor any other modes of transport] released by hypothalamic neurons into blood vessels
Pituitary apoplexy achieved with magnetic resonance imaging and blood tests. Treatment is by the timely correction of hormone deficiencies, and in many cases surgical decompression is required. Many people who have had a pituitary apoplexy develop pituitary hormone deficiencies and require long-term hormone supplementation. The first case of the disease was recorded in 1898. The initial symptoms of pituitary apoplexy are related to the increased pressure in and around the pituitary gland. The most common symptom, in over 95% of cases, is a sudden-onset headache located behind the eyes or around the temples. It is often associated with nausea and vomiting. Occasionally,
