However, most human brains have major parts in common. Your cerebrum is the largest part of your brain. It is made of two connected halves, or hemispheres. Scientists divide each side of the brain into four parts that are approximately located on the front, top, back, and side of the head: the frontal, parietal, occipital, and temporal lobes ...
The dura mater: This is the thick, outmost layer located directly under the skull and vertebral column.; The arachnoid mater: This is a thin layer of web-like connective tissue.Under this layer is cerebrospinal fluid that helps cushion the brain and spinal cord. The pia mater: This layer contains veins and arteries and is found directly atop the brain and spinal cord.
