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

    The autonomic nervous system controls the heart and has two branches; the sympathetic nervous system and the parasympathetic nervous system. When the body is undergoing muscular work, fear or stress the sympathetic nervous system will be active. When the sympathetic nervous system is active it will cause every heartbeat to increase in strength and heart rate. During resting, peace and contentment the parasympathetic nervous system is active and it calms the heart output. During periods of fright, flight and fight the sympathetic nervous system is boosted by the hormone; adrenaline. The nerves of the adrenaline are the cardiac nerves. A special cluster…

    The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. Animals with backbones and spinal columns have a central and a peripheral nervous system. The central nervous system is made up of the brain, spinal cord and retina. The peripheral nervous system consists of sensory neurons, ganglia and nerves that connect to one another and to the central nervous system.

    The nervous system’s function is to monitor stimuli occurring inside and outside the body, process and interpret this sensory input, and respond by activating effector organs. It consists of the Central Nervous System (brain and spinal cord), and the Peripheral Nervous System (neurons that carry messages to and from the CNS).…

    The first system of the human body is the nervous system. The nervous system is made up of two parts: the central nervous system, which includes the brain and the spinal cord, and the peripheral nervous system, which consists of neurons found all over the body. A person’s brain is like a control room. It helps regulate all the other systems of the body by sending signals down the spinal cord and through the body nerves to all the other organs. In addition, the brain has different parts which specialize in processing thoughts, memories, feelings, dreams, speech, physical coordination, balance, hunger, and sleep. The fact that the nervous system is extremely complicated, without it, your systems in your body could not communicate.…

    Inside our brain, there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor nerves, which relay messages from the central nervous system, to all the skeletal muscles of your body. The autonomic nervous system regulates the body’s internal environment, which consists of organs, glands, and blood vessels. An example is breathing.…

    The nervous system comprises the central nervous system which is made up of the brain and spinal cord, with the main functions being processing information and determining responses and the peripheral nervous systems which is made up of all sensory, motor and inter neurons within the body and these are located on peripheral nerves. All of them work together to collect sensory data and also control the actions of the body. Sensory neurons collect sensory information and convey it to the brain, and motor neurons transmit the necessary signals to receptive tissues whilst inter neurons create circuits which creates communication pathways between the central nervous system and the two other neuron types. There are many sub neurons that fall under…

    In humans, the nervous system is divided into the central nervous system (CNS), which consist of the brain and spinal cord, and the peripheral nervous system (PNS), which contains all the nerves that run everywhere in the body. The brain and the spinal cord serve as the main processing center for the entire nervous system, and control all the workings of the human body. They work together to let messages flow back and forth between the brain and the body.…

    Yes, the autonomic nervous system is responsible for promoting the release of epinephrine from the adrenal glands during times of distress. In particular, this results in the rapid release of stored glucose (glycogen) into the blood stream which leads to a cascade of increased alertness, heart rate, blood pressure, and respiratory rate. These changes to homeostasis are useful for their purposes, however, the body is incapable of remaining in this state for extended periods of time. Increased heart rate, which results in a need for increased respiration to oxygenate the hardworking cells, can result in a type of heart arrhythmia known as tachycardia. This can lead to structural heart damage, vessel damage, and electrical conduction damage within…
