Major Functions of the Brain

The five major structures of the brain are myelencephalon, Metencephalon, mesencephalon, diencephalon and telencephalon. The myelencephalon carries signals from the brain to the entire parts of the human body and it is also uniquely shaped looking like a little net. The Metencephalon is made up of ascending and descending tracts just like the myelencephalon. It has two major divisions which are pons and the cerebellum. The mesencephalon has two divisions also and they are the tectum and the tegmentum. The diencephalon is composed of two structures which are thalamus and hypothalamus. These two structures play a lot in our senses and important roles like sexual activity and sleep. The telecephalon initiates voluntary movement and interprets sensory input. It also mediates complex processes such as speaking, learning, and problem solving. The information below will be describing the five major structures and the functions that take place in the human body from the major structures in the brain.
The myelencephalon is made up of tracts that carry signals from the rest of the brain throughout the entire part of the body. The myelencephalon has a unique shape. It has a reticular shape meaning it looks like a little net. It is made up of about 100 tiny nuclei that occupies the central core of the brainstem. Parts of the myelencephalon play a part in arousal. The functions of the myelencephalon include sleep, attention, and movement, the maintenance of muscle tone and various cardiac, circulatory and respiratory reflexes. According to this collection of nuclei, it is an activating system and this means that it can be misleading to us.
Metencephalon is also made up of many ascending and descending tracts that are also a part of the reticular formation. The structure creates a bulge which these are pons, and it is located on the brain stems ventral surface. There are two major divisions of the Metencephalon which are the pons and the cerebellum. The
