Answer:
Parasympathetic nervous system
Explanation:
The parasympathetic nervous system of the autonomic nervous system is activated to restore the body's energy level after the emergency conditions. This division of the autonomic nervous system triggers the digestion and absorption of nutrients so that body cells obtain and conserve energy.
Some of the responses generated by activated parasympathetic division are increased activity of glands associated with the digestive system and increased the contraction of smooth muscles of the digestive tract. The parasympathetic nervous system also slows down the responses required for physical activities such as heart rate and breathing rate.
Oncogenes result from turning on, or activating proto oncogenes. Proto oncogenes are genes that code for positive cell cycle regulators, so proto oncogenes code for proteins that turn on cell division. Proto oncogenes are normal genes, but when they are mutated, they become oncogenes. Oncogenes are expressed too much, which makes them turn on cell division too much, which is cancer.
The right answer is glutamate
Glutamate is a major excitatory neurotransmitter associated with learning and memory.
It is also associated with Alzheimer's disease whose first symptoms are felt in memory.
Most people unknowingly consume monosodium glutamate (MSG), a commonly used food additive.
An experiment was done on healthy patients, giving them 12 grams of glutamate. It was found that the experience led to headaches, nausea or jaw pain in 50-60% of cases.
It was also measured the level of glutamate contained in the muscles of patients with jaw problems. The tests concluded that the most painful muscles were those containing the highest levels of glutamate.
According to him, one of the keys to chronic pain could lie in the development of drugs that reduce the rate of glutamate.
