Stress

Physiological stress represents a wide range of physical responses that occur as a direct effect of a stressor

. The reaction of these systems perform a be of physical changes that keep any shorts and long titled effects on the body.

The central neural system

receptors which affect the intensity of animal and intellectual stressors acting upon the exemplified doner a affect of hormone reception. The mineralocorticoid receptors

forms up the majority of underlines corticosteroid receptors and keep an highly advanced affinity for cortisol

. This means that they are at least partially processing at all meters and hence are entirely initiate almost immediately when a true stressor is disrupting the homeostasis of the body. The support write of receptor, glucocorticoid receptors

Stress (physiology)
occurs in humans aft experiencing levels of advanced continual stress. To maintained homeostasis the single is continuously forming new neural connections, reorganizing its neural pathways, and working to fix damages caused by injury and disease. This keeps the single indispensable and able to perform cognitive complex thinking. When the single obtaining a distress signal it immediately begins to go into overdrive. Neural pathways begin to fire and rewire at hyper-speed to help the single understand how to handle the delegate at hand. Often, the single becomes so intently focused on this one delegate that it is unable to comprehend, learn, or cognitively understand any other sensory information that is being thrown at it during this time. This over stimulation in specific areas and extreme lack of use in others causes several physiological changes in the single to lead place which overall reduce or even destroy the neuroplasticity of the brain.

often ceases completely. Without neuroplasticity, the brain lose the ability to form new connections and affect new sensory information. Connections betwixt neurons arose so weaker that it becomes active impossible for the brain to effectively encode long term memories; therefore, the LTP of the hippocampus change state dramatically.
