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.
Nerve cells use a variety of chemical messengers called neurotransmitters to communicate with each other. Neurotransmitters serve to carry messages between nerve cells by crossing the synapse, or space between nerve cells. Neurotransmitters also allow nerves to communicate with muscle cells in order to create motion.
