Brain and nerves

It is one of the most complex and vital organs in the human body, and the structure of the brain and nerves is mainly composed of three main parts. The brain, the spinal cord, and the extracerebral nervous system.

The brain is the control center of the body and is the main part of the central nervous system. The brain consists of several parts, each of which has specific functions.

The brain consists of the medulla and the pons. The medulla controls the basic functions of breathing, heart rate, and body balance. The diencephalon consists of the thalamus and hypothalamus, which are involved in regulating processes such as sleep and appetite, pain perception, emotions, and temperature regulation. / The cerebrum is the larger and more complex part of the brain and consists of different lobes (such as the frontal lobe, parietal lobe, temporal lobe, and occipital lobe). The different lobes of the brain control different functions such as hearing, vision, movement, memory, and language. / The spinal cord is a long nerve column that extends downward from the brain. The spinal cord is responsible for transmitting nerve information between the brain and the rest of the body and is very sensitive. This part of the nervous system is responsible for voluntary and involuntary movements such as unconscious breathing / Extracerebral nervous system

This system includes nerves that exit the brain and spinal cord and extend to the rest of the body. These nerves are divided into two groups

The motor nervous system This part of the nerves is responsible for controlling voluntary movements such as muscle movement. And the autonomic nervous system This system is responsible for controlling involuntary processes such as heart rate, body temperature, digestion and a number of other organ processes.
