<h3>What are Neurotransmitters?
</h3>
Neurotransmitters, which are organic compounds, play a major role in the language that neurons use to communicate with one another and with their final targets. Following electrical stimulation, these substances are produced and act on their particular receptors to start a response that can be as simple as a muscle contraction or as extremely complex as starting a chain reaction that eventually changes how the organism behaves. Neurotransmitters can have multiple functions; depending on where they act, they can be neuromodulators or, in some cases, neurohormones.

Explanation:
Muhammad, or Mohammed, (born c. 570, Mecca, Arabia—died June 8, 632, Medina), Arab prophet who established the religion of Islam. The son of a merchant of the ruling tribe, he was orphaned at age six. He married a rich widow, Khadījah, with whom he had six children, including Fāṭimah, a daughter. According to tradition, in 610 he was visited by the angel Gabriel, who informed Muhammad that he was the messenger of God. His revelations and teachings, recorded in the Qurʾān, are the basis of Islam. He began to preach publicly c. 613, urging the rich to give to the poor and calling for the destruction of idols. He gained disciples but also acquired enemies, whose plan to murder Muhammad forced him to flee Mecca for Medina in 622. This flight, known as the Hijrah, marks the beginning of the Islamic era. Muhammad’s followers defeated a Meccan force in 624; they suffered reverses in 625 but repelled a Meccan siege of Medina in 627. He won control of Mecca by 629 and of all Arabia by 630. He made his last journey to Mecca in 632, establishing the rites of the hajj, or pilgrimage to Mecca. He died later that year and was buried at Medina. His life, teachings, and miracles have been the subjects of Muslim devotion and reflection ever since.
