The medulla, pons, and the cerebellum are three main parts of the hindbrain.
Brain is the centre of the nervous system. It is enclosed in the skull cranium. The primary regions of the brain are the forebrain, midbrain and the hindbrain. The forebrain consists of the cerebrum and diencephalon. The midbrain is a small tubular region between the forebrain and the hindbrain. The hindbrain is made up of the medulla oblongata, pons and cerebellum.
Cerebellum is the second largest portion of the brain which helps in maintaining the body's equillibrium, coordinates muscular movements and body posture. Pons is the structure located in the brain stem which relays impulses from medulla to cerebellum and vice versa. Medulla oblongata is the lowest part of the brain stem controlling involuntary reflexes and has the respiratory and cardiac centres in it controlling respiration and heart beats respectively.

Explanation:
Before explaining the following phenomenon, it is good to clarify one thing: the laws of thermodynamics are fulfilled and cold water usually freezes faster than hot water. However, and although it seems counterintuitive, it has been observed for centuries that this fact is not always fulfilled and under certain circumstances, hot water freezes before cold water. Aristotle was the first to record this phenomenon, but it was not published as a scientific observation until 1969 by Erasto Mpemba. Precisely due to the surname of the scientist born in British Tanganyika, this phenomenon is known as the Mpemba effect. A curious effect that has recently been having an impact due to a new viral called "boiling water challenge" and consists of throwing boiling water into the air to see how it quickly freezes and turns into snow.
