The first stage of the GAS model when one first becomes aware of the stressor is known as ———————-
Alarm reaction.
_______ is any response to nervous system that does not require awareness
Unconscious responses
______________ are an involuntary and unconscious response to a stimuli involving the spinal cord and occurs without input from the brain
Spinal reflexes
________ - afferent neurons: which transmit information from the body to the brain
________ - efferent neurons: which transmit information from brain to body
_________ : which communicate between sensory and motor neurons
sensory
motor
interneurons
Neurons communicate via a process called _______ which uses _______________
Neurotransmission, electrochemical energy
_______________ are specialised chemical messengers. They transmit information from one neuron to the next
Neurotransmitters
Relatively permanent strengthening of synaptic connections resulting from repeated activation of a neural pathway
Long term potentiation
Repeatedly lower levels of activity in a neural pathway and involves relatively permanent weakening of synaptic connections
Long term depression
_______ is the creation of new extensions on a neuron to allow it to make new connections with other neurons.
Sprouting
_______ occurs when new connections are made between neurons to create alternate neural pathways
Rerouting
______ is the elimination of weak, ineffective or unused synapses (and therefore connections to other neurons)
Pruning
stress that lasts for a relatively short time
Acute
stress that continues for a long time
Chronic
A bidirectional (two way) communication link between the central and enteric nervous systems
Gut-brain axis
Subdivision of autonomic nervous system and the two way communication that occurs between the enteric nervous system and the CNS and happens via the vagus nerve and gut microbiota
Enteric nervous system
evaluation of stress
irrelevant
stressful
benign positive
primary appraisals
harm/loss
threat
