The blood clotting function of the body speeds up in order to reduce bleeding and prevent excessive blood loss in the event of an injury sustained during the response. Increased muscle tension in order to provide the body with extra speed and strength, which can result in trembling or shaking until the tension is released.
The instinctive drowning response is an instinctive reaction that occurs in humans, particularly in non-swimmers, when close to drowning.It is focused on attempting to keep the mouth above water to the exclusion of useful effort to attract help or self rescue, and is often not recognized by onlookers.
Body reactivity is usually understood as an organism's functional ability of its body to react adequately in response to influence the environment. It is not to be confused with resistance, which is its physiological stability against the influence of pathogenic factors. The body reactivity can range from homeostasis to a fight or flight response.
At this point, all of the body's resources are eventually depleted and the body is unable to maintain normal function. The initial autonomic nervous system symptoms may reappear (panic attacks, muscle aches, sore eyes, difficulty breathing, fatigue, heartburn, high blood pressure, and difficulty sleeping, etc.).
As a result, cellular energy failure, depolarization of neuronal and glial membranes, edema, and excess neurotransmitter and calcium ion release can occur. [11] This ultimately ends with cell death, as cells succumb to a lack of nutrients to power their metabolism and to a toxic brain environment, full of free radicals and excess ions that ...
This same reaction mechanism is also responsible for the loss of body heat in the extremities, demonstrated via the Hunter's Test. One clinical test for the patient that can be performed is the QSART, or the Quantitative Sudomotor Axon Reflex Testing, which stimulates the autonomic nervous system of an individual by stimulating sweat glands ...
An altered level of consciousness can result from a variety of factors, including alterations in the chemical environment of the brain (e.g. exposure to poisons or intoxicants), insufficient oxygen or blood flow in the brain, and excessive pressure within the skull. Prolonged unconsciousness is understood to be a sign of a medical emergency. [3]
Usually the onset of the startle response is a startle reflex reaction. The startle reflex is a brainstem reflectory reaction (reflex) that serves to protect vulnerable parts, such as the back of the neck (whole-body startle) and the eyes (eyeblink) and facilitates escape from sudden stimuli. It is found across many different species ...
