Where in your body do you think cell division is occurring?
Answers
Answer:
Everywhere except in gonad cellsExplanation:
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46. In the sex cells, meiosis occurs where the DNA is halved and the daughter cell has only 23 chromosomes.

It is also involve in filtration of noise with processing of messages or make it slower during sleep, it alters the brain's electrical activity, electrical voltage of brain waves and the speed.
The primary function of RAS is higher at brain centres when important messages are received and filter the important messages, for example The eye sends messages to the brain through the optic nerve.
If the RAS system is damaged, it can cause sleep problems, lethargy, or coma, also play a role in narcolepsy and degenerative brain disorders like Parkinson's disease and supranuclear palsy
