Understanding the Big Brain, its Functions, Structure and Parts (Complete)

Understanding Big Brain, Function, Structure and Parts (Complete) – In this discussion we will explain about the big brain. Which includes the understanding, function, structure and parts of the cerebrum with a complete and easy-to-understand discussion. For more details, please read the review below carefully.

Understanding Big Brain, Function, Structure and Parts (Complete)

Let's discuss the meaning first carefully.

Understanding Big Brain Otak

The cerebrum or cerebrum is the embryonic period, the central nervous system that makes up the shallow central canal of the ventricles and forms the white and gray parts. The gray part consists of the cell body of the neuron, dendrites, and unmyelinated axons, then the white part contains the myelin-wrapped axons, making the neuron white.

The cerebrum is the largest part of the brain. For adults, the weight of the cerebrum is about 1 kg or 2/3 of the weight of the whole brain. The cerebrum is composed of the right and left halves.

The right part of the cerebrum controls the left side of the body and the left side of the cerebrum controls the right side of the body. As the largest structure of the brain, the cerebrum has a very important function for the human body.

And also as a major part of the nervous system, the cerebrum has hundreds of neurons that send information to other parts of the body.

Function of the Big Brain (Cerebrum)

The cerebrum is the central controller of most human activities. The cerebrum has a role in regulating conscious movement (striated muscles or skeletal muscles), memory, emotion, perception of stimuli, learning functions, regulating sensory organs, and others. But the main function of the cerebrum (cerebrum) is as a center for regulating consciousness and memory centers.

Structure and Parts of the Big Brain (Cerebrum)

The following will explain what are the structures and parts of the cerebrum.

According to the Structure

Based on its structure, the cerebrum is divided into two main parts, namely the cerebrum cortex (outer part) and basic ganglia (inner part).

Cerebrum Cortex
The cortex is a thin, gray layer with billions of nerve cell bodies. The cortex is also known as the gray matter area. Nerve cells that are interconnected with each other form like a chain, making the information received by one nerve cell can be passed on through communication with other nerve cells. The cortex is divided into three main areas, including:

• Sensory Area. Is an area whose job is to interpret sensory information (stimuli), such as: light, taste and sound.
• Motor Area. Is the area whose job is to control the muscles to make a movement, such as when stepping on a thorn, a reflex will occur by moving the foot away from the thorn.
• Association Area. Is an area whose function is to record experiences experienced by the body (memory), will and intelligence and also regulates some language functions.

Basic Ganglia
The basic ganglia are white areas that contain a lot of dendrites and axons. This layer is thicker than the cortex. The basic ganglia function is to coordinate movements, regulate involuntary movements, cognitive functions and emotional functions.

According to the Lobe

Based on the lobes, the cerebrum is divided into four parts, including the frontal lobe, parietal lobe, temporal lobe, and occipital lobe.

Frontal Lobe
This lobe is located at the front of the cerebrum. The function of this frontal lobe is as a regulator of motor activity (movement) consciously, speaking ability, thinking ability (solving problems) and emotions.

Pariental Lobe
This lobe is behind the frontal lobe at the top of the cerebrum. The main function of the parietal lobe is as a sensory center or reception of stimuli such as touch, pressure, temperature, pain and so on.

Temporal Lobe
This lobe is under the parietal lobe, precisely on the side of the cerebrum. The main function of the temporal lobe is as a center for hearing and language functions.

Occipital Lobe
This lobe is at the back of the cerebrum. The main function of the occipital lobe is as a visual center (vision).
