Therefore, some parts of the so-called 'transition zone' - the layer between the outer mantle and the lower mantle, which extends between 410 and 660 kilometers below the surface of the Earth - participate in the creation of the Earth's magnetosphere.
The epidermis of the inner or ventral mantle surface is continuous with the epidermis of the body of the conch, contains numerous mucus cells, and may form folds in Lobatus gigas, whereas the epidermis of the outer mantle surface, continuous with the exterior surface of the visceral mass, has sparse mucus cells, shorter epidermal cells, and may be more heavily sinuated while typically not forming folds (Hyman 1967).
An MRI exam spotted damage caused by cysts in his cerebral cortex, which is the outer mantle of brain tissue, as well as the brain stem, including the cerebellum, which sits at the back of the head above the spinal cord.
Outer mantle layer loosely plectenchymatous (type E, Agerer, 1987-2008); hyphae light honey brown with no matrix material, rarely septate and clamps absent.
The smaller flame produced is due to the fact that it does not have an outer mantle, which can be advantageous as the combustion chamber can be made physically smaller reducing the risk of flame impingement.
These measurements yielded a mean waviness index for inner and outer mantle IM-3 fibers in both hyper-inflated and contracted tissue for each squid.
4B-C): The mycor hiza in plane view shows pseudoparenchymatous mantle with few hyphae running parallel Outer mantle layer not gelatinous, transparent in color, pseudoparenchymatous arrangement with few hyphae of 2 um running parallel (Type K, Agerer, 1987-2002), cells oval to rounded 3-5 um long and 2-3.5 um wide, unique organization, matrix granular, cell contents granular and oily droplets, hyphal junction not seen, hyphal anastomoses absent.
Among more than 500 genes that are normally expressed at significantly different levels in the front versus the lower middle part of the brain's outer mantle, or cortex, only 8 showed such differences in brains of people with autism, say researchers funded in part by the National Institutes of Health.
Saturn's tidal pull would cause much of the moon's ice to melt and then refreeze as an outer mantle. As the moon spiraled into the planet, Canup's calculations show, the icy layer would be stripped off to form the rings.
The star's outer mantle, with most of its mass, was ejected spherically, creating a round blast wave.
As a small star dies, its outer mantle radiates away, leaving a carbon-oxygen "white dwarf" core with about two-thirds as much matter as our sun, packed into a space the volume of our Earth.
On Earth, olivine is abundant in the Earth's outer mantle, the layer just below the surface crust.
