Richard Ramirez, the serial killer who terrorized Southern California in the 1980s as the Night Stalker, has died in prison while awaiting execution. Ramirez died of natural causes at Marin General Hospital. He was 53 years old. San Quentin State Prison spokesman Lt. Sam Robinson confirmed Ramirez's death Friday.
The somatic nervous system (SoNS or voluntary nervous system) is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements. The SoNS consists of afferent nerves and efferent nerves.
Smooth muscle, such as in the digestive system, is also controlled by the autonomic nervous system. Like heart muscle, it is not under our conscious control. The SNS is responsible for controlling voluntary body movements, such as movement of the arms and legs. It is also responsible for receiving sensory information such as touch, hearing, and sight. The SNS contains neurons that connected with the skeletal muscles, skin, and sense organs. Neurons that control skeletal muscle and organs are called motor neurons.
