question 1 of 7 course: Biomedical Science(Degree)
question 1 of 7 course: Biomedical Science(Degree)

Q: What is the main component of the cell membrane?

Did You Know?

False. Histamine is best known as a mediator released from mast cells and basophils during allergic reactions, causing symptoms like itching and vasodilation. While it does have some roles in the brain, the primary neurotransmitter involved in the sleep-wake cycle is hypocretin/orexin. Histamine in the brain actually promotes wakefulness.
