Welcome to softilmu, a simple blog that shares knowledge with sincerity. This time we will share knowledge about BRAIN, some of the topics discussed are Understanding the Brain, Parts of the Brain, Brain Structure and Brain Function. Go ahead, hopefully the knowledge can be useful J
A. UNDERSTANDING THE BRAIN
The brain is the most important organ in the human body which is the center of the nervous system. The volume of the brain is around 1,350 cc and has 100 million nerve cells or neurons to support its function. The brain is located in the head, and has several functions, namely:
- As a regulatory center some of the actions experienced
- As a central regulator of body organs (eg regulating the work of the heart, liver, etc.)
The brain is the controller of the body. If a person has a healthy brain, it will encourage a healthy body. On the other hand, if a person’s brain is in an unhealthy condition, then it is the cause of all problems in the body.
B. PART OF THE BRAIN
Overall, the human brain is divided into four parts, namely:
1. Big Brain (Cerebrum)
As the name implies, the cerebrum is the largest part of the brain. The cerebrum is the part that distinguishes the human brain from the animal brain. With a big brain, humans can think, control thoughts, speak, remember, and even speak. A person’s intelligence is also measured based on the ability of the big brain.
The cerebrum is further divided into several parts that compose it, namely:
- frontal lobe,namely the part of the cerebrum that occupies the leading part of the structure of the cerebrum. The temporal lobe has a relationship with human behavior, such as the ability to move, cognitive, planning, problem solving, creativity, emotional control center, sex, and language skills.
- parietal lobe,is the part of the cerebrum in the middle. Parietal lobe is associated with the body’s sensory processes in the form of pressure, touch, touch, and others.
- Occipital Lobe,is the part of the cerebrum that is at the back. This part of the cerebrum has a relationship with human vision (visual), so that the body is able to distinguish everything that is seen by the eye.
- temporal lobe,is the part of the cerebrum located on the left and right sides of the brain. The temporal lobe is related to human (verbal) voice, so that with this temporal lobe, humans can speak and distinguish the various languages used.
2. Small Brain (Cerebellum)
The cerebellum is the part of the brain that is under the occipital lobe of the cerebrum, precisely at the back of the head, and is associated with the upper neck. The cerebellum has a relationship with human movement functions, such as controlling human movement, controlling coordination between muscles, regulating body balance, and regulating body posture and position. Without a small brain, you can imagine how miserable human life is. Movement becomes uncoordinated, resulting in a person unable to use his muscles to carry out activities.
3. Brainstem (Brainsteam)
The brain stem is a part of the brain that is no less important than the cerebrum and cerebellum. The brain stem is in the upper neck and extends all the way to the human spinal cord. The brain stem regulates basic human functions, such as regulating the respiratory process, the heart rate process, the kidney work process, and other things that are vital for humans. Therefore, in medical terms it is known as brain stem death, which is a condition of brain stem injury that causes the person to be biologically dead.
The brain stem is further divided into several parts, namely:
- Midbrain (Mesencephalon), is the part of the brainstem that connects the cerebrum and cerebellum. The midbrain is related to the visual process in humans.
- Medulla Oblongata,is the starting point for the nerves that will go to the spine so that they will continue throughout the body. The medulla oblongata is concerned with controlling the automatic functions of the organs in humans.
- Punch,is the part of the brainstem that is located below the medulla oblongata and regulates and transmits all information to other parts of the brain.
4. Limbic System
The limbic system is the part of the brain located in the middle of the brain. The components of the limbic system are the hypothalamus, thalamus, amygdala, limbic cortex, and hippocampus.
The limbic system is the part of the brain associated with the human consciousness. Emotion center, data center, thirst center, hunger center, sex drive center, and many more. Even LeDoux termed the limbic system as a seat for all human passions, a place of appreciation, honesty, and a place where love and hate flow.
C. BRAIN STRUCTURE
The human brain is made up of two cells, namely glia and neurons. Glia are cells that protect neurons, or can be called neuron lining cells. While neurons are nerve cells that carry all the information the body needs to the brain. Neorun carries that information in the form of action potentials.
Between one neuron and another neuron are interrelated, so that it can be likened to an unbroken chain. One neuron will carry information in the form of action potentials to other neurons by participating in carrying chemicals called neurotransmitters. These neurotransmitters are carried and sent through synapses (a gap between neurons). Humans or even other living things have hundreds or even millions of neurons that are interconnected to carry all kinds of information to the brain.
D. THE FUNCTION OF BRAIN
As previously mentioned, the brain is the most important organ in the human body. Without the brain, humans cannot live and develop. This is evidenced by the function of the brain which is very sacred to the body. The following is a summary of the functions of the human brain, namely:
As a regulatory center for carrying out activities or moving, cognition, able to make plans, able to solve problems, provide judgment, stimulate creativity in humans, control feelings, control behavior related to sex and also be able to speak in general
- As a sensor for feelings, for example, pressure, pressure, responds to touch and produces pain.
- As a tool for translating verbally so that someone is able to hear, be able to capture and interpret information and be able to capture language in the form of sound.
- As a center for the entry of visual information to be translated in the form of vision that is in accordance with the original.
- As a center for regulating movement, coordination between body muscles and regulating balance, so that a person will be able to move properly and not fall.
- Functions in human visual translation, such as moving the eyeball, increasing or decreasing the pupil of the eye (according to the incoming light), and also regulating the movement of the human body.
- Controlling the automatic functions of the brain, such as regulating heart rate, regulating blood circulation in the human body, regulating breathing and also regulating the human digestive system.
- As a guardian of the body, whether asleep or awake.
- produces feelings, regulates emotions, regulates hormone production such as the function of the hormone testosterone, maintains homeostasis, creates thirst, creates hunger, creates desire for sex, stimulates feelings of pleasure, regulates body metabolism and also regulates human long-term memory.
