Briefly outline the sequence of events that occur in the HPA axis when a stressor occurs. Suggest how dysregulation of the axis may be involved in hypothalamus.
What will be an ideal response?
Ans: (1) The hypothalamus produces corticotropin-releasing hormone (CRH); (2) CRH, in turn, produces adrenocorticotropic hormone (ACTH) in the pituitary gland; (3) ACTH in the blood, in turn, causes the adrenal glands to produce glucocorticoids, such as cortisol. The HPA is ultimately under the excitatory control of the amygdala and the inhibitory control of the hippocampus. Dysregulation of the HPA axis has been related to vulnerability to psychosis among adolescents, and HPA overactivity is associated with depression.
