Everything we see, hear, touch or feel is a creation of our
nerve system. The main laboratory of the nerve system is the brain. The brain
is the most important and wonderful organ in the human body. Without this amazing
organ, probably we couldn’t evolve or develop everything we see. In physiology
the brain is referred to as central nerve system (nerve system in cranium).
The central nerve system is made from 5 different parts or
brain: hindbrain, midbrain, small brain, interbrain and forebrain. The medulla
oblongata is in the lower back part of the cranium. The most important vital
function is in the hindbrain.
The center for respiration, hearth work, sweets,
sneeze, cough, puke are founded in the hindbrain.
In the middle of the central nerve system there is the state
midbrain.
Its function is to regulate the muscle reflex and keep the muscle
tonus of skeleton musculature.
Bellow the main brain there is the cerebellum.
This brain also has two little hemispheres.
Although very small it contains 50
percent of all nerves in the central nerve system. Inside this part there is the
center of poise and nicety. We can’t walk without the small brain.
The interbrain is made from thalamus, hypothalamus and
subthalamus. These three parts regulate some of the most vital functions in the
human body (angst, thirst and happiness). These parts produce hormones which
are very important for the normal function of the body.
This brain is
connecting the endocrine system with the nerve system and because of that it is
very important.
The forebrain is biggest of all brains which all of us have.
The apogee of evolution is developing the forebrain and cortex.
The cortex is a
part which takes the signals from the body, elaborate and deliver them to some
parts of the human body. This process happens in part of a second.
Also, inside
this part are the centers for memory, ear, stimulation, speaking and everything
you can imagine in the moment. Without the cortex we couldn’t think and without
the cortex life wouldn’t exist. Every animal that has a brain also has a
cortex, but humans have the most developed cortex.
All of these parts work together in a perfect way.
