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.
The nervous system uses chemical messengers called neurotransmitters to relay messages from one part of the nervous system to the other. They travel from one nerve cell, or neuron, to the next bringing messages to and from the body to the brain.The communication lines in your CNS are called tracts.ou can think of the spinal cord as an expressway between the brain and the peripheral nervous system. It also has sensory and motor neurons that are responsible for your reflexes (e.g. knee jerk reflex). The spinal cord is enclosed within a canal made by your vertebral column.
