Neuroscience: Neurotransmitters (small molecule and neuroactive)‚ storage release removal and disease. 1. The brain is made up of neurons that process and transmit information by electrochemical signaling. Neurotransmitters are endogenous chemicals which relay‚ amplify‚ and modulate signals between a neuron and another cell. Chemical messengers must fulfill four criteria to be considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of

muscle should remain tightly closed to prevent the contents of your stomach from coming back up into the esophagus and burning its lining with hydrochloric acid. Drinking a lot of coffee will promote the release of the stress hormones cortisol and epinephrine. These chemicals increase your body’s heart rate‚ blood pressure and tension levels – the old ‘fight or flight’ response. All of this depends on how much coffee and caffeine your body can handle at one time. Although your shoe size isn’t a factor

The ingredient that provides energy is Caffeine. Caffeine does this by mimicking epinephrine‚ which stimulates the body. 3) An energy drink that does not contain caffeine could have a placebo effect on the user‚ mimicking the effects of caffeine. 4) The ingredients in these drinks are helpful to athletes because the temporary amount

Thermogenesis is the process of heat production in organisms. It occurs mostly in warm-blooded animals‚ but a few species of thermogenic plants exist. One form of thermogenesis is called thermo-regulatory thermogenesis. This is involved with keeping the temperature of the human body regulated. The average body temperature is 98.7 degrees (F)‚ which is quite a bit higher than the ambient (surrounding) temperature in most cases. There are two types of thermo-regulatory thermogenesis: shivering and
