![Anatomy of the Brain: Ventricles](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14904.jpg)
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral…
![Cerebrum: Anatomical Overview II](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14906.jpg)
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters…

The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and…
![Diencephalon: Anatomical Regions](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14909.jpg)
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast…
![Diencephalon: Thalamus and Information Relay](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14910.jpg)
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals…
![Cerebellum: Anatomical Regions](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14912.jpg)
The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal…
![Brainstem](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14913.jpg)
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a…
![Functional Brain Systems: Limbic System](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14915.jpg)
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of…
![Functional Brain Systems: Reticular Formation](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14916.jpg)
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within…
![Spinal Cord: Cross-sectional Anatomy](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14918.jpg)
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the…
![Spinal Cord: Information Processing](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14919.jpg)
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS).…
![Cranial Nerves: Overview and Anatomy](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14921.jpg)
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are…
![Cranial Nerves: Types Part I](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14922.jpg)
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs…
![Spinal Nerves: Anatomy](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14924.jpg)
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These…
![Spinal Nerves: Plexus I](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14925.jpg)
