Here are diagrams of the human brain, detailed and scientifically accurate, illustrating the brain's structure.
The brain is a vital organ in the human body and serves as the center of the nervous system. It is responsible for processing sensory information, controlling movement, regulating vital functions, and enabling higher cognitive functions such as thinking, learning, and memory.
The brain is composed of billions of neurons (nerve cells) interconnected by trillions of synapses, which allow communication between cells.
The brain is protected by the skull and the meninges (three layers of connective tissue) and is surrounded by cerebrospinal fluid, which provides additional protection and support.
The blood-brain barrier, a selective semipermeable membrane, helps maintain a stable environment by restricting the passage of substances from the bloodstream into the brain tissue.
Here is a classification of the brain's main regions:
1. Cerebrum:
The largest part of the brain, responsible for higher cognitive functions. It is divided into two hemispheres (left and right) and four lobes:
a. Frontal lobe
b. Parietal lobe
c. Temporal lobe
d. Occipital lobe
2. Cerebellum:
A region located at the back of the brain that is responsible for motor coordination, balance, and movement precision.
3. Brainstem:
The lower part of the brain that connects to the spinal cord and is responsible for basic life-sustaining functions.
The brainstem can be further divided into three regions:
a. Midbrain
b. Pons
c. Medulla oblongata
4. Diencephalon:
A region located between the cerebrum and brainstem, which consists of:
a. Thalamus
b. Hypothalamus
5. Limbic system
A group of interconnected structures responsible for emotions, motivation, memory, and learning. Key components of the limbic system include the hippocampus, amygdala, and cingulate gyrus.
