What are the valleys separating the convolutions on the surface of the cerebrum?
Sulci
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 organelles inside the cell have membranes with many convolution and why?
The mitochondria has a membrane with many convolutions because it increases the surface area for ATP synthesis
Why do cell membranes have convolutions?
To increase surface area, allowing greater contact area for 'transport' of nutrients (movement of substances across the membrane).
What is the explanation for the fact that most cells are small and have cell membranes with many convolutions?
Small cells are better able to transport material more efficiently. Many convolutions increase the surface area of the cell, thus allowing for more interactions between the cell and its environment. A large cell has greater volume to its surface area and if this is too large, it will not get enough protein and oxygen.
The surface of the cerebrum is folded into elevations that resemble speed bumps are called what?
convolutions or gyri
Convolutions of the brain provide increased what?
The convolutions increase the surface are of the cerebrum.
What do you call the folds that can be found in the brain?
The folds on the surface of the brain are called gyri.
What do convolutions do?
Convolutions create a greater surface area within the same size skull
What are the valleys separating the convolutions on the surface of the cerebrum?
Sulci
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.
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 role do convolutions play in the brain?
They provide more surface arean for nerves and such.
What are the shallow folds of the cerebral cortex called?
The Sulcus is a shallow furrow on the surface of the brain separating convolutions.
What increases the surface area of the brain?
The convolutions in the brain increase surface area. In simpler words, those lines and ridges in the brain are what increases the surface area.
What are the convolutions of the brain?
The convolutions in the cerebrum increase surface area
Why do Cells have convolutions?
The are convoluted to increase the amount of surface area that is available for chemical reactions and other interactions.
