Document Summary
As a system we can classify in three groups or three parts: motor, sensory and autonomic. Autonomic: controls nerve supply or innervation of internal organs in thoracic cavity, abdominal cavity, and pelvic cavity. Smoot muscle, which is located in one of blood vessels, endocrine glands, sweat glands. Autonomic nervous system has two parts: sympathetic and parasympathetic. Sympathetic system: when your body is active, the sympathetic system is active (hiking, swimming, dancing). More active when you sleep/rest the heart rate is lower than average. Decreases/calms down the heart activity respiration system as well. When you sleep the digestive system is more active. Sympathetic system: location-red color on slides from t1 up to l2 or l3. Location of sympathetic system is t1 to l2 or l3, it contains two types of fibers, preganglionic and postganglionic fibers. Travel to the sympathetic ganglia on left and right side of spinal cord. Meets with postganglionic fiber two fibers have a synapse inside the sympathetic chain.
