Peripheral Nervous System

The nervous system is one of the most important systems in the body. The nervous system helps to keep the human body in balance. There are several important parts of the nervous system; the brain, spinal cord, and nerves. Each part of the nervous system has different jobs. There are two main parts of the nervous system peripheral and central.
The peripheral nervous system is a collection of peripheral nerves, ganglia and specialized sensory structures that, as a unit, carries sensory and motor information between all organs and body system. The peripheral nervous system is divided into two major parts, somatic and autonomic nervous system. The somatic nervous system is made up of nerves that connects to voluntary skeletal muscles and to sensory receptors. Theses nerves cars information using the skin, muscles and joint to pass on to the central nervous
The autonomic nervous system is made up of nerves that connect to the heart, blood vessels, smooth muscles and glands. The Autonomic nervous system is separate from the Central nervous system but is controlled by the Central nervous system. The Autonomic nervous system controls the automatic voluntary and visceral functions. The Autonomic nervous system controls our heart rate and breathing patterns. The Peripheral nervous system has two branches. Sympathetic division is the first out of the two branches of the automatic nervous system that mobilize the body’s resources for emergencies. Sympathetic division is responsible for the fight or flight response. Special sympathetic nerves send signals to the adrenalin glands triggering the release of hormones. The second branch of the Autonomic nervous system is called parasympathetic division. This is the branch of the Autonomic nervous system that usually conserves bodily resources. This slows the heart rate, lowers blood pressure and promotes
