TY - CHAP M1 - Book, Section TI - The Autonomic Nervous System A1 - Waxman, Stephen G. PY - 2017 T2 - Clinical Neuroanatomy, 28e AB - The autonomic (visceral) nervous system (ANS) is concerned with control of target tissues: the cardiac muscle, the smooth muscle in blood vessels and viscera, and the glands. It helps maintain a constant internal body environment (homeostasis). The ANS consists of efferent pathways, afferent pathways, and groups of neurons in the brain and spinal cord that regulate the system's functions. It is modulated by supraspinal centers such as brain stem nuclei and the hypothalamus.
