The myelin sheath is the protective layer, which is present in the outer layer of the neural cells. This myelin sheath prevents the loss of electrical impulses, which are being conducted in the neurons. This also act as an insulator between neuron and its external environment.
This layer is mainly made up of the protein and fatty substance. The degeneration of the myelin sheath result in many neurological disorders.
Hence, the correct answer is myelin sheath.
The geosphere is considered that portion of the Earth system that includes the Earth's interior, rocks and minerals, landforms and the processes that shape the Earth's surface. The geosphere may be taken as the collective name for the
- hydrosphere (The hydrosphere is the liquid water component of the Earth. It includes the oceans, seas, lakes, ponds, rivers, and streams. The hydrosphere covers about 70% of the earth surface)
- cryosphere (The cryosphere is the frozen water part of the Earth system. The Beaufort Sea, north of Alaska. One part of the cryosphere is ice that is found in water),
- atmosphere( is a layer or a set of layers of gases surrounding a planet or other material body)
- lithosphere is the substantial, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere below. The lithosphere is further subdivided into tectonic plates. The lithosphere is the most rigid of Earth’s layers.
Hi,
here u go!!
Air masses are slowly pushed along by high-level winds, when an air mass moves over a new region, it shares its temperature and humidity with that region. ... For example, when a colder air mass moves over warmer ground, the bottom layer of air is heated. That air rises, forming clouds, rain, and sometimes thunderstorms.
hope it helps!!
