Hypothalamus, Neuroendocrine System, and Autonomic Nervous System

The hypothalamus is a very small nuclear mass found at the base of the third ventricle in the diencephalon. Its functional potency is related to its control of the hypophysis and the descending autonomic fibers, which affect preganglionic parasympathetic and sympathetic nuclei in the brain stem and the thoracic, lumbar, and sacral spinal cord. In addition, this diencephalic region, with its important tracts, forms part of the Papez circuit and must be included in any discussion of the limbic (or emotional) brain (Chapter 14).
