Nervous System Lecture 12: The Cerebrum (Part 2)

The cerebrum is a major part of the brain, responsible for higher-level functions like thought, memory, and voluntary actions.
Key Structures include: brainstem, cerebellum, diencephalon, limbic system, and the cerebrum itself.
The cerebrum is divided into two hemispheres (left and right).
Each hemisphere is divided into four lobes: frontal, parietal, temporal, and occipital.
A crucial structure connecting the two hemispheres is the corpus callosum.
The cerebral cortex is the outermost layer of the cerebrum, vital for processing information.
The cortex is composed of gray matter, which contains mainly nerve cell bodies.
Beneath the gray matter is white matter, composed mostly of nerve cell axons.
Image references show anatomical structures such as sulci (grooves), gyri (bumps), a longitudinal fissure and the various lobes of the brain
A nucleus is a cluster of nerve cell bodies inside the CNS.
Diagrams and images depict the structure and location of the cerebral lobes (frontal, parietal, temporal, occipital), sulci, and gyri.
The images also illustrate the relative thickness of cerebral cortex to white and grey matter and important measurements are included.

Explore the intricate details of the cerebrum, the major part of the brain responsible for higher functions such as thought and memory. This lecture covers the hemispheres, lobes, and key structures like the corpus callosum and cerebral cortex. Dive into the anatomy with clear diagrams and references to enhance your understanding of this vital brain region.
