What do convolutions do?
Convolutions create a greater surface area within the same size skull
The convolutions on the cerebrum's surface is called?
The convolutions on the cerebrum's surface are called gyri and sulci. Gyri are the raised folds, while sulci are the grooves that separate them. These convolutions increase the surface area of the brain, allowing for more neurons to be packed within the limited space of the skull.
Explain the significance of the different in color and its relationship to the convolutions?
It is darker on the outside due to the presence of fissures. The darker the color, the deeper the fissure. The deeper the fissure, the more surface area there is, and the more convoulted the brain is.
Why do cells have membranes with many convolutions?
Cell membranes have many convolutions because they increasee the surface area to volume ratio, thus increasing the diffusion rate.
What are the depressions between the convolutions of the cerebrum?
The answer is sulcus.
What is the definitions of convolutions and sulci?
convolutions: a form or part that is folded or coiled; one of the convex folds of the surface of the brain.Sulci: a shallow groove, such as that between gyri on the brain surface.
What are the convolutions of the brain?
The convolutions in the cerebrum increase surface area
What is polygyria of the brain?
polygyria - a brain with an excessive amount of convolutions
How might large and complex nasal cavities conserve water during exhalation?
Large nasal cavities that are very complex have convolutions. These convolutions help to keep the moisture in when the animal exhales.
What is the more convolutions that are found in the brain of an animal?
the less healthy the brain
What role do convolutions play in the brain?
They provide more surface arean for nerves and such.
How do the convolutions and sulci of the sheep cerebrum compare with the human cerebrum in number?
I think the sheep cerebrum has less Yes, the sheep cerebrum does have less of the convolutions and sulci, because the human cerebrum has evolved mental capacity over time.
