(Sympathetic nervous system pathway)
Endocrine system
Network of glands - hormone release
HPA pathway
Which system return the body to normal functioning?
Parasympathetic nervous system

ACTH major stress hormone which stimulates the adrenal glands > trigger release of corticosteroids to further produces arousal
Sympathetic nervous system
During stress stimulates organs
Release of Adr and NAdr
DSM-5 PTSD
Exposure to traumatice event, Intrusive symptoms, Avoid trauma linked stimuli, Negative changes in cognition, Changes in arousal/reactivity
PTSD and stress pathways
Heightened arousal in the stress pathways
Multifinality
People with similar beginnings may wind up at very different end points
Equifinality
Different developmental pathways may lead to the same end point
Memory and dissociative disorders
In dissociative disorders one part of the person’s memory (identity) becomes dissociated (separated) from the self
