What is resilience? Used differently by a range of fields from psychology to engineering, resilience has no single widely accepted definition. The concept typically connotes an ability to âbounce backâ from a stress or disturbance, potentially returning to a pre-stress norm or a transformed post-stress condition.
a chemical transmitter substance produced by cells of the body and transported by the bloodstream to the cells and organs on which it has a specific regulatory effect. adj., adj hormoÂ´nal. Hormones act as chemical messengers to body organs, stimulating certain life processes and retarding others.
Therefore, neurotransmitters make possible the nerve impulses of one cell influence the nerve impulses of another, thus allowing brain cells to talk to each other, so to speak. The human body has developed a large number of these chemical messengers in order to facilitate internal communication and signal transmission within the brain.
