PSYCH 3M03 Chapter Notes - Chapter 6: Anterior Pituitary, Cutaneous Receptor, Adrenal Medulla
Document Summary
Reflexes: eg/ withdrawal of hand when touch hot object; pain of heat straight to spinal cord then rapid involuntary response. Integration of autonomic, endocrine, and skeletomotor mechanisms: eg/ panting. Hypothalamic regulation: presumably integrates into drives and behaviour, specific regions of hypothalamus that are more implicated than other areas, heat dissipation response. Lesion area shivering response is lost. If you cannot feel pain, it will result in physical damage; eg/ if you do not withdraw your hand from heat, it will result in bad burns. Psychological dimensions that are confusing become very focused on trivial injuries, yet pain is innate. Amount perceived often not proportional to injury. Adaptive value: disincentive for maladaptive and self-injurious behaviour. Where fear comes from: punishes activity when rest and recovery are needed. In most organs of the body (not the brain), skin, muscle full of receptors. Free nerve endings (will leave to pain following injury)
