There are two types of stress response depending on the appraisal of the threat. Fight or Flight is activated for short-term stressors, different systems are activated for long-term or chronic stress. APPRAISAL OF STRESSOR The situation is appraised via sensory systems and stored memories. Hippocampus + Amygdala try to recognise emotional reactions to stimuli and access stored memories for potential danger  If the situation is deemed stressful, the hypothalamus is alerted. Hypothalamus controls the HPA axis (pituitary-adrenal system) for chronic stress and the SAM pathway for acute stress SAM PATHWAY Situation perceived as stressful due to emotions and memories Hypothalamus alerted and recognises stress as ACUTE SAM pathway activated (sympathetic branch of ANS) Adrenal Medulla stimulated (in adrenal gla...

FUNCTION OF ENDOCRINE SYSTEM FUNCTION:  To secrete hormones in the blood stream to regulate our bodily functions. Works w/ nervous system to regulate and coordinate physiological processes Provides a chemical system of communication via the blood stream. Uses a gland network, which secretes hormones (chemical messengers) throughout the body. HORMONES - Chemicals from glands which circulate bloodstream and are carried to target structures around the body. Each hormone will stimulate a part of the body, which leads to other hormones being released like adrenaline or oestrogen PITUITARY GLAND - The gland which exerts the most influence, this "Master Gland" can control all other endocrine glands. It's governed by the hypothalamus. PITUITARY HORMONES ACTH - Regulates the steroid hormone Cortisol (C is released from adrenal gland) OXYTOCIN - Facilitates in bonding between mother and child and stimulates uterus contraction during childbirth  VASOPRESSIN...
