Sympathetic Nervous System

The nervous system is made of two systems which consist of the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain, spinal cord, and the nerves in the body. The peripheral nervous system is composed of nerves and a bundle of nerve cells called ganglia, which is located on the outside of the spinal cord and the brain. The nervous system is responsible for controlling and communicating with other parts in the body to maintain blood pressure, breathing, and other essential functions to carry out an ordinary lifestyle (Zimmermann, K.A., 11 March

The central nervous system is composed of the brain and spinal cord and the peripheral nervous system is composed of the body’s sensory receptors, muscles, and glands. The peripheral nervous system is made up of somatic and automatic. Somatic is the voluntary movement of our skeletal muscles. When we hear the bell ring, our somatic nervous system carries the message to the brain and the brain reports back to our muscles. The autonomic nervous system controls our glands and muscles in our internal organs. Some things this nervous system does is taking control of our digestive system and our heart beat. There are two functions of the autonomic nervous system- the sympathetic and the parasympathetic nervous system. The sympathetic nervous system arouses and expands energy. If someone gets excited or nervous in a situation, their blood pressure will rise, their digestion will slow down, their heartbeat will accelerate, their blood sugar will rise, and they will sweat to cool down. The parasympathetic is the opposite. It tries to conserve energy by decreasing your heartbeat, lowering your blood sugar, and so

The nervous system is made up of three vital parts; the brain, spinal cord and nerves. This system controls everything we do from breathing, to running to making our heartbeat fast or slow. The nervous system is very complicated although it can be broken down into smaller components.

Medications used for nervous system disorders such as: ADHD, Schizophrenia, Bipolar Disorder and more have been used for years to treat these disorders and others. Most medications have a positive effect on a person, when used correctly and with the right body chemistry. Other times, these medications can cause more harm than good.

The first communication system is the Nervous System (NS), which includes the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS is comprised of the brain, spinal chords and nerves, and the PNS is comprised of sensory neurons, ganglia (clusters of nerves) and nerves that connect to one another and to the CNS. Sensory neurons act as receptors, and respond to physical stimuli such as light and sound, and send feedback to the CNS regarding the body’s surrounding environment which leads to, as previously mentioned, motor neurons in the CNS, or even in the ganglia of the PNS, transmitting the signals to the muscles and glands. This is how the receptors interact with the effectors via the CNS. In the PNS, there is a sub-system called the Autonomic Nervous System (ANS), which regulates glands, smooth muscle, heart rate etc, under subconscious control. The ANS has two ‘divisions’: the sympathetic division, which speeds up functions and can be asscociated with ‘emergency reactions’ to unfamiliar or extreme events, and the parasympathetic division, which slows down functions and is associated with automatic responses to day to day life. These two divisions of the ANS are essential to homeostais in that they allow for subconscious responses in relation to external stimuli. The ANS also bases its

The nervous system is figuratively a command center of various organisms, including humans, in which its primary role is to receive and send messages. These messages are carried by nerve cells, known as neurons. The two major components of the system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) (Eunice Kenedy Shiver National Institute of Child Health and Human Development 2013). Previous educational research demonstrate that the CNS contains the brain and the spinal cord. The brain, one of the most important organ, is also made up of many parts, where each part has its own roles, such as the control over awareness, movements, sensations, thoughts, speech, and memory. For instance, the occipital lobe, which is

Stage1- Alarm stage is the immediate response to the stressor. This immediate response will result in a person's sympathetic nervous system being stimulated. The stimulation of the person's sympathetic nervous system is characterized by the increase in one’s heart rate, blood pressure, and respirations. This reaction is also known as a fight or flight response when adrenaline is released in a person body which stimulates the sympathetic nervous system. This stage gives us the strength to fight off a threat.

The Parasympathetic is the one that controls homeostasis, this will control the body’s responses when at rest. Sympathetic is the system that responses to a perceive threat responses, and this system is responsible for the flight or fight response. The difference between the two is the parasympathetic is responsible with anything when you’re at rest, where the sympathetic is responsible for anything threatening.

Sympathetic nervous system is the system that prepares the body for intense physical activity and is often referred to as the fight-or-flight response. (p.11) As stated in the book this nervous system is encharged of preparing your body for physical activity. The sympathetic systems as well has effects over several other organs. Affected human parts include the heart, liver, the digestive system and several more. Together the parts of the body involved in the process prepare the body for physical activity such as a emergency.

First we would have to assume that you want the response to if you were afraid of the dog. In that case your fight or flight response would be triggered which starts in your limbic system where it is than transmitted to your hypothalamus which activates that response. The sympathetic nervous system would respond by releasing epinephrine, dilate your pupils and respiratory passages, dilate your coronary arteries and speed up your heart, cause your hair to stand on end, cause a dry mouth, increase blood flow to your skeletal muscles, promote glycogen breakdown and glucose mobilization, and inhibit digestive and urinary function. This allows our bodies to act quickly and to the most efficient degree with the energy that is produced in this response.

The nervous system allows the animal to quickly detect, communicate information about its external and internal environment. There are two major parts of our nervous system are the central nervous system (CNS) and peripheral nervous system (PNS).

The nervous system is a system of nerve cells that carry messages to and from the brain, spinal cord, and other parts of the body. It has two parts of it: the Central nervous system and the Peripheral nervous system. The central nervous system contains the brain The central nervous system contains the brain, spinal cord, and retina. While the peripheral nervous system consists of sensory neurons and nerves that connect the central nervous system to arms, hands,and feet. The nervous system contains other body systems like the skeletal system which helps the individual move and make a frame for the other organs. An example would be the bones in the skeleton. The nervous system interacts with the bones because of the calcium they receive from

The human nervous system is complex one that is composed of two main parts: the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain and the spinal cord, that both serve different purposes. The brain intercepts and stores information as well as send actions to the muscles, organs, and glands. The spinal cords serves as a connecter for the brain and the peripheral nervous system. The peripheral nervous system is separated into two different parts: the autonomic and somatic nervous system. The autonomic nervous system is responsible for regulating functions in the body automatically without conscious thought about it. The Somatic nervous system is responsible for carrying sensory information

The nervous system is what helps communicate with the entire body and its activities. The nervous system is made up of two major parts of the system; the central and the peripheral. The central nervous system (CNS) is made of the brain and spinal cord, (Get Healthy Stay Healthy, n.d). The job of the CNS is that is to integrate the information that is coming back from the body and peripheral nervous system. It works subconsciously and consciously to control all the activities. The work that the peripheral nervous system carries out is to communicate messages between the central nervous system and the body, (Ptdirect, 2010).
