Blood Vessels of the Skull Blood Vessels of the Skull The brain requires a rich blood supply, and the space between the skull and cerebrum contains many blood vessels . These blood vessels can be ruptured during trauma, resulting in bleeding. Groove for middle meningeal artery

The Cerebrum The Cerebrum The largest portion of the brain is the cerebrum. It consists of two hemispheres that are connected together at the corpus callosum. The cerebrum is often divided into five lobes that are responsible for different brain functions. Corpus callosum

The Cerebrum The Cerebrum The cerebrum’s surface—the neocortex —is convoluted into hundreds of folds. The neocortex is where all the higher brain functions take place. Neocortex

The Neocortex The Neocortex The cerebral cortex is a thin layer of cells about 1.5 to 4 mm thick. The cortex provides the connections and pathways for the highest cognitive functions, such as language and abstract thinking. The cerebral cortex contains about 25 billion neurons, more than 62,000 miles of axons, and 300,000,000,000,000 synapses. Neocortex layer The thin layer of the neocortex is dense with neurons.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
