- The nervous system is composed of the brain and spinal cord, together known as the central nervous system, and a vast array of peripheral nerves that transmit information to and from these central structures. The nervous system may be damaged by infection, injury, vascular problems, inflammation, and degeneration.

The Nervous System: Fight or Flight This feeling of stress, often referred to as the fight-or-flight response, is directed by the sympathetic nervous system. The sympathetic nerve system is used by your body in response to stress, or, in other words, anything that your body perceives as a threat. Acting intelligently, your body’s response to threats is to prepare for action: fight-or-flight. Even thinking of a stressful event will cause you to experience the influence of the sympathetic nerve system in your body.

- The parasympathetic nervous system (PNS) controls homeostasis and the body at rest and is responsible for the body's rest and digest function. The sympathetic nervous system (SNS) controls the body's responses to a perceived threat and is responsible for the fight or flight response.he sympathetic nervous system, also part of the autonomic nervous system, originates in the spinal cord; specifically in the thoracic and lumbar regions. It controls the body's fight or flight responses, or how the body reacts to perceived danger.

Nervous System and Brain Health The autonomic nervous system has two parts: the sympathetic and the parasympathetic nervous systems. The sympathetic nervous system prepares the body for sudden stress, like if you see a robbery taking place.

Body Systems & How They Work Together Integumentary and Nervous Systems. Your skin is called the integumentary system, which is your body's first line of defense. It regulates your body temperature, protects underlying layers of tissue from sun damage and prevents pathogens from freely entering your body.

- Our nerves carry pain signals to the brain about damage to parts of the body, but nerves can also be a cause of pain themselves. This can be from damage to nerves because of medical conditions, through injury or pressure, such as a trapped nerve. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion and temperature regulation. 2  Motor nerves. 3  These nerves control your movements and actions by passing information from your brain and spinal cord to your muscles.

- The anatomy of nerves. The nervous system is one of two key control systems of the body that sends and receives messages, enabling us to function properly. It is able to do this because of the nerves that connect the brain and spinal cord with our peripheral regions (legs and arms) and viscera (organs).

What Is Spinal Stenosis? This can cause pain and other problems. Your spine is made up of a series of connected bones (or “vertebrae”) and shock-absorbing discs. It protects your spinal cord, a key part of the central nervous system that connects the brain to the body. The cord rests in the canal formed by your vertebrae.

- 1 Skin protects body tissues and organs against injuries. 2  The nerves in your skin receive the stimuli that tell your brain when your skin has been touched. 3  The nerves in your skin also help your brain respond to sensations of hot and cold.

Outline of the human nervous system Outline of the human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves, which are long fibers that connect the CNS to every other part of the body.

- central nervous system, coordination, flexibility, pain reduction, protective mechanisms, strength, Z-Health. One of the most important things to understand about your body is that it is largely governed by the central nervous system (the “CNS”.) The CNS is composed of your brain, the spinal cord and the nerves. It is a lightning fast communication system that controls every aspect of your sensation and movement.

Nervous System: Facts, Function & Diseases The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort, according to Merck Manuals. The somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin.

- The sympathetic branch of your autonomic nervous system originates in the spinal cord. It goes into action to prepare the body for physical or mental activity. In response to a stressor, the sympathetic nervous system orchestrates what you familiarly call the fight-or-flight response.

Nerve Pain Linked to Medical Conditions and Injury To break this down even further, individual nerve cells consist of an axon (the inner pathway whereby information is transmitted) and a myelin sheath (a fatty outer covering that protects the nerve cell and helps transmit information). 1  An injury or irritation to any part of nerve structure can cause nerve pain.

Nervous System Nerves. Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium. Sensory. 2  The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body’s internal and external conditions. 3  These signals are then passed on to the central nervous system (CNS) for further processing by afferent neurons (and nerves).

Nervous system The nervous system is the part of an animal 's body that coordinates its voluntary and involuntary actions and transmits signals to and from different parts of its body. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago.he central nervous system functions to send signals from one cell to others, or from one part of the body to others and to receive feedback. Malfunction of the nervous system can occur as a result of genetic defects, physical damage due to trauma or toxicity, infection or simply of ageing.

- Figure 1.6. The central nervous system, which includes the spinal cord and the brain, is the most protected organ in the human body. It is protected from the external environment by three barriers: skull, meninges, and cerebral spinal fluid (CSF).he CNS, in turn, is divided into the brain and the spinal cord, which lie in the cranial cavity of the skull and the vertebral canal, respectively. The CNS and the PNS, acting in concert, integrate sensory information and control motor and cognitive functions.

Symptoms of Stress We have an involuntary nervous system called the Autonomic Nervous System (ANS), which contains two types of nerves. 1  Parasympathetic nerves conserve energy and keep the systems in a relatively resting state. 2  Sympathetic nerves prepare the body for action through the Fight-or-Flight reaction.

The Nervous System An easy way to think about the CNS is all nerve encased in bone. In the case of human that includes just the brain and spinal cord. We will talk WAY more about the brain in the next chapter. Peripheral Nervous System (PNS) The PNS consists of all the other nerves in our body or all nerves that are not encased in bone. The PNS is divided into two categories, the Somatic and Autonomic Nervous Systems. The Somatic Nervous System controls all of our voluntary muscle movements.
