Estimates of the US sports industry's size vary from $213 billion to $410 billion. In 1997, 25% of tourism receipts in the United States were related to sports tourism; this would have valued the market at approximately $350 billion annually. Many US sporting events routinely attract international visitors.
carries info (APs) AWAY FROM the CNS to effectors. (muscles and glands) 1. Somatic division of the efferent nervous system (Somatic nervous system or SNS) a.Somatic efferent motor) neurons control skeletal muscle; skeletal muscle is the effector for the somatic. motor division of the PNS. b. Control may be voluntary (usually) or involuntary, because most of the SNS is mapped to the cerebral cortex.
The somatic nervous system controls all voluntary muscular systems within the body, and the process of voluntary reflex arcs. The basic route of nerve signals within the efferent somatic nervous system involves a sequence that begins in the upper cell bodies of motor neurons (upper motor neurons) within the precentral gyrus (which approximates the primary motor cortex).
