![]() ![]() ![]() Stress and strong emotions can present with respiratory symptoms, such as shortness of breath and rapid breathing, as the airway between the nose and the lungs constricts. The bronchioles then transfer oxygen to red blood cells for circulation. Air comes in through the nose and goes through the larynx in the throat, down through the trachea, and into the lungs through the bronchi. The respiratory system supplies oxygen to cells and removes carbon dioxide waste from the body. For those who develop chronic pain conditions, stress-relieving activities have been shown to improve mood and daily function. Relaxation techniques and other stress-relieving activities and therapies have been shown to effectively reduce muscle tension, decrease the incidence of certain stress-related disorders, such as headache, and increase a sense of well-being. Muscle tension, and eventually, muscle atrophy due to disuse of the body, all promote chronic, stress-related musculoskeletal conditions. Individuals who are fearful of pain and re-injury, and who seek only a physical cause and cure for the injury, generally have a worse recovery than individuals who maintain a certain level of moderate, physician-supervised activity. What determines whether or not an injured person goes on to suffer from chronic pain is how they respond to the injury. Often, but not always, there may be an injury that sets off the chronic painful state. Millions of individuals suffer from chronic painful conditions secondary to musculoskeletal disorders. Musculoskeletal pain in the low back and upper extremities has also been linked to stress, especially job stress. When muscles are taut and tense for long periods of time, this may trigger other reactions of the body and even promote stress-related disorders.įor example, both tension-type headache and migraine headache are associated with chronic muscle tension in the area of the shoulders, neck and head. Chronic stress causes the muscles in the body to be in a more or less constant state of guardedness. With sudden onset stress, the muscles tense up all at once, and then release their tension when the stress passes. Muscle tension is almost a reflex reaction to stress-the body’s way of guarding against injury and pain. The involuntary part of the PNS includes the sympathetic, parasympathetic, and enteric nervous systems.When the body is stressed, muscles tense up. These parts are linked in the CNS, but not in the PNS, where they usually occur in different parts of the body. The CNS and PNS both include voluntary and involuntary parts. The involuntary system is broken down into three parts It’s always active and regulates a person’s heart rate, breathing, metabolism, among other critical body processes. The body’s involuntary (vegetative or automatic) nervous system controls processes in the body that a person doesn’t consciously control. The body’s voluntary (somatic) nervous system controls things a person is aware of and can control consciously, such as moving their head, arms, legs, or other body parts. ![]() But it also has voluntary and involuntary nervous systems. There are two types of nervous systemsĮveryone’s body has a CNS and a PNS. All remaining nerves in other parts of the body are part of the PNS. It includes the nerves in the brain and spinal cord. The CNS is located in the skull and vertebral canal of the spine. They are distinguished by their location in the body and include the central nervous system (CNS) and the peripheral nervous system (PNS). The human nervous system is divided into two parts. There are two parts of the nervous system Interneurons: Interneurons sends messages from one neuron to another.ĥ.Receptors: Receptor neurons sense the environment (light, sound, touch, and chemicals) around you and convert it into electrochemical energy that is sent by sensory neurons.Motor: Motor neurons carry signals from the CNS to the outside parts of the body.Sensory: Sensory neurons deliver electrical signals from the outer parts of the body - the glands, muscles, and skin - into the CNS. ![]()
