One of the distinguishing characteristics of nervous tissue is how difficult it is to repair damage to nervous tissue. Explain factors limit neurogenesis in the CNS of adults, why is it so hard to repair a damaged nerve

Inhibitory influences from neuroglia, and the absence of growth-stimulating cues.

Explanation:

Neurogenesis in adults is limited by Inhibitory influences from neuroglia, mainly from oligodendrocytes, and the absence of growth-stimulating cues that are present during fetal development. It is so hard to repair a damaged nerve because nerve cell like other cells can't divide and increase in number, they can't renew themselves. Due to no division, the nerve cells does not increase in number and therefore can't repair themselves.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
