Is cerebrum a part of the brain?

Answer 1

A cerebral hemisphere (hemispherium cerebrale) is defined as one of the two regions of the brain that are delineated by the body's median plane. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter called the cerebral cortex that is supported by an inner layer of white matter. The hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers, and also by other smaller commissures, including the anterior commissure, posterior commissure, and hippocampal commissure. These commissures transfer information between the two hemispheres to coordinate localized functions. The architecture, types of cells, types of neurotransmitters and receptor subtypes are all distributed among the two hemispheres in a markedly asymmetric fashion. However, it must be noted that, while some of these hemispheric distribution differences are consistent across human beings, or even across some species, many observable distribution differences vary from individual to individual within a given species.

Answer 2

Because you can have 3 halves.

answ2. Much of the body of mammals (and many other animals as well) has a "bi-lateral symmetry". That is, it has a more or less matched right and left half, which mirror each other.

Thus you have a pair of arms, lungs, kidneys, legs, nostrils, eyes, ears and so on, so it is no surprise that the brain is divided into two halves. In general, each side of the brain controls the actions on the opposite side of the body.

There are exceptions to this general rule; you have only one liver, digestive system, bladder, and so on. And in the case of the eyes, part of each eyes signals goes to both halves of the brain.

There are animals with circular symmetry, but even the insects have a bi-lateral plan. So it is obviously one that carries advantage. By contrast, there appear to be no animals that have a tripod locomotion or balance, in spite of its stability and simplicity.

Answer 3

This is called the falx cerebri and is an extension of the dura matter surrounding either cerebral hemisphere.

Answer 4

Yes: There's the left hemisphere & the right hemisphere.

Answer 5

no, do not be confused with the other one with carabela cortex which is divided by 2

cerebral cortex is divided by 3
