The Peripheral Nervous System

•Interneurons- neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs

•Somatic nervous system- the division of the peripheral nervous system that controls and the body's skeletal muscles

•Automatic nervous system- the part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). It's sympathetic division ariuses; its parasympathetic division calms

•Sympathetic nervous every system- the division of the automatic nervous system that arouses the body, mobilizing its energy in stressful situations


•Parasympathetic nervous system- the division of the automatic nervous system that calms the body, conserving its energy
