PSYCH 150 Lecture Notes - Lecture 9: Pituitary Gland, Adrenal Gland, Blood Sugar
Document Summary
Cognitive: thoughts that you have during the event. Behavioral: things you do in response to stress (e. g. pacing, tapping, yelling at someone) Physical responses: can be potentially damaging to health. The following two systems are connected to regions in the brain involved in cognition, emotion, etc; have numerous effects on the body related to health. Hypothalamus releases crf which travels to the pituitary. Pituitary gland produces acth which travels to the adrenal gland. Adrenal glands produce cortisol which has numerous effects on the body. Measure cortisol levels from saliva: during stressful events: reactivity and recovery. Measure cortisol levels over a period of time cortisol levels peak 20-40 min following stressor. Recovery change from the peak; how long it takes for someone to return to baseline: duri(cid:374)g (cid:862)rest:(cid:863) teady-state. Decreases over the course over the day. Negative feedback: feedbacks to the hypothalamus and pituitary; high levels of cortisol stop producing crf and acth.
