Begin by understanding the structure of the brain stem, which is a crucial part of the central nervous system.
The brain stem is composed of three main regions: the midbrain, the pons, and the medulla oblongata.
The midbrain is located at the top of the brain stem and is involved in functions such as vision, hearing, and motor control.
The pons is situated below the midbrain and above the medulla oblongata, playing a role in relaying signals between different parts of the brain and the cerebellum.
The medulla oblongata is the lowest part of the brain stem, responsible for regulating vital functions such as breathing, heart rate, and blood pressure.
