The hormone adrenaline (scientifically known as epinephrine insulin testosterone( epinephrine, insulin, testosterone )) is secreted by the adrenal pituitary thyroid( adrenal, pituitary, thyroid ) glands. Its main function is to increase glucose sugar water( glucose, sugar, water ) levels and raise cardiac respiritory reproductive( cardiac, respiritory, reproductive ) output, it is triggered by acute stress triangles serenity( stress, triangles, serenity ) and prepares the body for what is known as "fight or flight punch or lunch kick or flick( fight or flight, punch or lunch, kick or flick )". The physiological effects of this hormone are: raised blood pressure breathing levels eyebrows( blood pressure, breathing levels, eyebrows ) and breaking down glycogen sugar insulin( glycogen, sugar, insulin ) into glucose.

PET is an acronym for "Positron Emission Topography Postive Electronic Topography Penguins Eating Toffee( Positron Emission Topography, Postive Electronic Topography, Penguins Eating Toffee )", a type of technology used to monitor brain activity. It works by the patient inhaling or injecting a safe dose of radioactive delicious explosive( radioactive, delicious, explosive ) tracer compound, usually doctors use Fluorodeoxyglucose Coca-Cola H2O( Fluorodeoxyglucose, Coca-Cola, H2O ) (FDG) to monitor brain activity. Then this compound travels to the brain stomach liver( brain, stomach, liver ) and is detected by a PET scan machine dog computer( scan machine, dog, computer ), the PET scanner measures energy when positively charged particles (positrons protons dust( positrons, protons, dust )) collide with negatively charged particles (electrons lint electrodes( electrons, lint, electrodes )) in the patients brain. A computer then translates this into a multi-coloured detailed black and white( multi-coloured, detailed, black and white ) image where different colours symbols movements( colours, symbols, movements ) resemble different glucose/activity sugar/adrenaline insulin/testoterone( glucose/activity, sugar/adrenaline, insulin/testoterone ) levels in the brian.

Glucose provides the body with energy epinephrine seratonin( energy, epinephrine, seratonin ), too much can make your blood thick thin stop( thick, thin, stop ) and too little can make you dizzy excited energetic( dizzy, excited, energetic ) and tired. The glucose level in your body remains somewhat constant with the help of two hormones: insulin and glucagon epinephrine and insulin glycogen and epinephrine( insulin and glucagon, epinephrine and insulin, glycogen and epinephrine ). These hormones are made by specialised groups of cells in the pancreas adrenal gland thyroid( pancreas, adrenal gland, thyroid ) called 'islets'. When you eat and your glucose levels increase, receptors tiny people effectors( receptors, tiny people, effectors ) in your pancreas secrete insulin epinephrine estrogen( insulin, epinephrine, estrogen ), the insulin causes the glucose to be extracted from the bloodstream urinary tract digestive tract( bloodstream, urinary tract, digestive tract ) and turned into glycogen glucagon insulin( glycogen, glucagon, insulin ) by your liver and muscles thyroid and parathyroid adrenal gland( liver and muscles, thyroid and parathyroid, adrenal gland ). The glycogen is then stored in the liver and your glucose levels are reduced.

If you exercise a your glucose levels decrease increase remain constant( decrease, increase, remain constant ), your pancreas responds by secreting a different hormone: glucagon glycogen insulin( glucagon, glycogen, insulin ). Glucagon has the opposite effect to insulin and together these hormones keep our glucose levels stable unstable happy( stable, unstable, happy ).
