The Hormones of the Hypothalamus
Scientific American, 1972The isolation and synthesis of thyroid stimulating hormone-releasing factor (TRF or TSH-RF) and luteinizing hormone releasing factor (LH-RF) are discussed. Hypothalamic fragments of sheep brains were the source f rom which 1 mg of TRF was first extracted characterized and synthesize d.

The hypothalamus is an integral part of the neuroendocrine system. The anatomy, embryologic development, and normal function of the hypothalamus are described here. Pathophysiology of congenital abnormalities and brain injury is discussed and a case study examined. In addition, nursing implications of caring for such an infant are addressed.

The pathology of the hypothalamus
Clinics in Endocrinology and Metabolism, 1977The clinical effects of disease within the hypothalamus are largely dependent on the anatomical sites of the lesions. The importance of a knowledge of the nuclear topography and connections of the hypothalamus is therefore paramount for the study of clinico-pathological relationships. A detailed account of hypothalamic anatomy is not, however, possible

The effect of a transitory increase in plasma FSH and LH levels during the prepubertal period on puberty has been investigated. Twenty-day-old rats had been bilaterally ovariectomized and 24 hr later they received two ovaries of infantile rats beneath the kidney capsule. These rats exhibited precocious puberty. Animals into which two additional ovaries

Cephalalgia, 2009
Migraine is a complex brain disorder where several neuronal pathways and neurotransmitters are involved in the pathophysiology. To search for a specific anatomical or physiological defect in migraine may be futile, but the hypothalamus, with its widespread connections with other parts of the central nervous system and its paramount control of the ...

The hypothalamus forms part of the central autonomic network, regulating body homeostasis and controlling pain. To this effect, it is strongly wired to more rostral and caudal areas, in particular the brainstem periaqueductal grey, the locus coeruleus and the median raphe nuclei, all involved in autonomic and sleep mechanisms and also in the descending

The Hypothalamus and Hypertension
Physiological Reviews, 2001Most forms of hypertension are associated with a wide variety of functional changes in the hypothalamus. Alterations in the following substances are discussed: catecholamines, acetylcholine, angiotensin II, natriuretic peptides, vasopressin, nitric oxide, serotonin, GABA, ouabain, neuropeptide Y, opioids, bradykinin, thyrotropin-releasing factor ...

EXPERIMENTS with an analogue model of the heart, demonstrated by me1, show that a pulse may arise, in a fluid-filled elastic system, in either of two ways : in the first, energy is cycled into the system from a mechanical source, corresponding to the physico-chemical contraction of the ventricles ; in the second, pulsation can be derived from the ...

The hypothalamus and reproduction
American Journal of Obstetrics and Gynecology, 1972Abstract This article has been designed to review recent developments in the field of hypothalamic hormones involved in the control of reproductive functions. A brief resume of early physiologic and anatomic studies was presented initially to give a better understanding of the concept of hypothalamic regulation of the release of gonadotropic hormones ...

Optometry - Journal of the American Optometric Association, 2010
For nearly 2 millennia, signs of hypothalamic-related vision disorders have been noticed as illustrated by paintings and drawings of that time of undiagnosed Horner's syndrome. It was not until the 1800s, however, that specific connections between the hypothalamus and the vision system were discovered. With a fuller elaboration of the autonomic nervous
