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.

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 is the part of the peripheral nervous system that handles voluntary control of body movements. It contains all the neurons connected with skeletal muscles and skin. The Autonomic Nervous System is the part of the peripheral nervous system that acts as an involuntary control system b(elow the level of consciousness), and controls visceral functions. The ANS controls the connections between the brain, spinal cord and organs/glands, whereas the SNS connects external sensory organs through the brain to the muscles.
