Functions of the Nervous System
Central Regulation of Visceral Functions
Introduction

The levels of Integration of the Autonomic Nervous system within the CNS, much like the somatic system, are organized according to a specific hierarchy. Simple Reflexes, such as the contraction of a full bladder's musculature, are coordinated by centers in the Spinal Cord. This chapter examines The regulation of more complex reflexes. The centers controlling Respiration and Blood pressure are located in the Medulla Oblongata, while the centers for the pupillary light reflex and accommodation reside in the Midbrain. The integration of complex autonomic mechanisms responsible for maintaining the chemical constancy and Temperature of the body's internal environment takes place in the Hypothalamus. The hypothalamus is also linked to the limbic system, regulating emotions and instinctive behavior; these aspects of hypothalamic function are likewise discussed in this chapter.
