The human brain is the command center for the human nervous system. 00:00:04
It receives input from the sensory organs and sends output to the muscles. 00:00:09
The human brain has the same basic structure as other mammals' brains, 00:00:15
but is larger in relation to body size than any other brains. 00:00:19
The human brain is the largest brain of all vertebrates relative to body size. 00:00:26
It weighs about 1.5 kg. 00:00:33
The brain makes up about 2% of a human's body weight. 00:00:38
The cerebrum makes up 85% of the brain's weight. 00:00:44
It contains about 86 billion nerve cells, neurons. 00:00:49
It contains billions of nerve fibers, axons and dendrites. 00:00:55
These neurons are connected by trillions of connections, is located within the head. 00:01:00
The larger structures of the brain are the cerebrum, brain stem and cerebellum. 00:01:15
The cerebrum is a large part of the brain containing the cerebral cortex. 00:01:28
well as the hippocampus, basal ganglia and olfactory bulb. 00:01:35
In humans, the cerebrum is the uppermost region of the central nervous system. 00:01:42
Depending upon the position of the animal it lights, either in front or on top of the 00:01:47
brainstem. 00:01:53
In humans, the cerebrum is the largest and best developed of the three major divisions 00:01:54
of the brain. 00:02:00
The cerebrum is the newest structure in the phylogenetic sense and in mammals it is the 00:02:01
darkest and most developed out of unknown species. 00:02:07
The brainstem is the posterior parts of the brain, structurally continuous with the spinal 00:02:11
cord. 00:02:17
The brainstem includes the midbrain, the pons and the medulla oblongata. 00:02:19
The brainstem provides the main motor and sensory innervation to the face and neck via 00:02:25
the cranial nerves. 00:02:31
This is an extremely important part of the brain as the nerve connection of the motor 00:02:33
and sensory system from the main part of the brain to the rest of the body pass through 00:02:39
the brainstem. 00:02:44
The brainstem also plays an important role in the regulation of cardiac and respiratory 00:02:45
function. 00:02:51
It also regulates the central nervous system. 00:02:52
The cerebellum is a major feature of the hindbrain, of all vertebrates. 00:02:56
In humans, the cerebellum plays an important role in motor control, 00:03:01
and it may also be involved in some cognitive functions, 00:03:07
such as attention and language, as well as in regulating fear and pleasure responses. 00:03:12
It contributes to coordination, precision and accurate timing. 00:03:18
It receives input from sensory systems of the spinal cord. 00:03:24
In this image we can see what part of the brain controls each part of our body. 00:03:30
The main parts are feet, leg, knee, hip, trunk, elbow, wrist, hand, ring finger, middle finger, index finger, thumb, nape, eye muscles, face, lips, cheek, tongue, pharynx and larynx. 00:03:37
In our sport, gymnastics, we have to think twice what are we going to do and be very concentrated. 00:04:01
That's why when we are going to do a difficulty we are very serious and we take some seconds 00:04:07
before doing it. 00:04:15
When you are short on one part of the head you can die or not. 00:04:35
When you die is because the brain also die and all the organs of your body, including 00:04:39
the heart, stop working. 00:04:44
It gets two seconds until you die, if you survive you couldn't remember anything. 00:04:47
