PsychologyApproachesCore studiesBiopsychologyASAQA Created by: Betsy_2018Created on: 18-02-17 20:19 What is the basis of Biopsychology? The nervous system co-ordinates the workings or organs and cells by collecting, processing and responding to environmental info 1 of 17 What are the two parts of the Nervous System? Central Nervous System and the Peripheral Nervous System 2 of 17 What are the two parts of the central nervous system? The brain (central/master processing unit; 2 hemispheres and cerebral cortex); spinal cord (receives sensory info from PNS, responsible for reflexes) 3 of 17 What is the basis of the PNS? Neurons that transmit info to and from the CNS 4 of 17 What are the two parts of the peripheral nervous system? Automatic (involuntary) and Somatic (voluntary) nervous system 5 of 17 What are the two subunits of the Automatic Nervous System? Sympathetic: fight or flight; Parasympathetic: restores processes 6 of 17 What is the Endocrine System? Series of glands that secrete hormones (slowly, but in great strength) 7 of 17 How do hormones affect the body? Chemical substances that will enter any cell of the body that has a complementary receptor; makes the response diverse (across the whole body) 8 of 17 How do the Endocrine System and the ANS work together? The hypothalamus is triggered by a stressor, which activates the sympathetic branch of the ANS, as well as the Endocrine System 9 of 17 What is the function of the pituitary gland? Instructs other glands; releases oxytocin for bonding 10 of 17 What is the function of the testes? Release testosterone in males 11 of 17 What is the function of the ovaries? Release oestrogen and progesterone 12 of 17 What is the function of the thyroid gland? Produces thyroxine which affects heart rate, metabolism and growth 13 of 17 What is the function of the adrenal gland? Releases adrenaline 14 of 17 What is the function of adrenaline during the sympathetic state? Increases heart rate, breathing rate, muscle tension, sweat production, dilation of pupils 15 of 17 What is the function of adrenaline during the parasympathetic state? Restores digestion an the immune system and other functions to their normal states 16 of 17 What is a real life application of hormones affecting behaviour? Oxytocin was given to anorexia patients; negative focus on body and food was reduced dramatically 17 of 17
