Glioblastoma Multiforme
...  Multiforme? GBM is a disease that typically affects adults 40 to 70 years of age. Children ranging from 3 to 12 years old also suffer from the disease though cases are few and far in between. The cerebrum, particularly at the frontal and temporal lobes, is where glioblastomas usually develop during the early stages. Its definitive characteristic from other malignant brain conditions is that  ...

Visual Sense
...  rays are on the right focus, the image created is inverted. This makes the whole world inside the retina upside down. However, the action potential delivers the message to the visual cortex of the cerebrum and interprets the image as right side up. In wearing glasses that inverts the images, one person might see the world in an inverted orientation. But after a while, the brain can adapt to it  ...

Basal Nuclei
...  nuclei which are grouped together to perform one function. These are the corpus striatum and the substantia nigra. The corpus striatum differs from substantia nigra because it is found within the cerebrum, while the latter is found in the midbrain. Both of these types should exist in congruence with each other so that proper coordination or movements would occur. Anatomy The basal nuclei are  ...

Cerebrum
...  cerebrum is the largest part of the brain that constitutes the forebrain. It is the part of the brain that is responsible for all the voluntary actions of the body. It is located on top of the brainstem and is considered the most developed part of the brain. The cerebrum is the newest structure in the brain, phylogenetically speaking. This part of the brain is most-developed in mammals among  ...

Blood Supply to the Brain
...  artery. This artery, in turn, serves as the seed where two posterior cerebral arteries are created. The new set of arteries now takes charge of transporting the blood supply to the surface of the cerebrum, the dominant part of the human brain. They further branch out into posterior communicating arteries that are responsible for the Circle of Willis, also known as the cerebral arterial  ...

Mesencephalon
...  which deals with reflexes for the auditory stimulation. There are two cylindrical structures located there- those are the cerebral peduncles. These peduncles then create connection for the cerebrum and other parts of the brain. Meanwhile, the red nucleus is located between the cerebral aqueduct and the cerebral peduncle. It could be found deep in the midbrain. The red nucleus unites  ...

Reticular Formation
...  reticular formation pertains to a complex network of nerve fibers and nuclei within the brain stem. Its network aids in creating the reticular activating system, the one that is responsible for the cerebrum. This network is extended until the spinal cord, the pons, midbrain, thalamus and hypothalamus. Most of the structures in the brain send and receive fibers which go up and down within the  ...

Ventricles Of The Brain
...  ventricles of the brain are attached to each other, together with the spinal cord- particularly the central canal. The two lateral ventricles are situated together with the cerebrum in the same hemisphere, and is just under the corpus collosum. The third ventricle is located in the diencephalon, specifically in the thalami. These three ventricles are connected through an opening called the  ...
