MICROANATOMY

Detailed explanation-1: -Human nerve cells differ from human muscle cells because different sets of genes are expressed; in each type of cell, different genes are transcribed into mRNA and translated into protein.

Detailed explanation-2: -The muscle and nerve cells vary in the expression of different genes, leading to various gene products. The variation of genes may be present in different types of cells. But the gene expression determines the variation in cellular metabolism of cell types.

Detailed explanation-3: -Muscle cells are able to detect mechanical, metabolic, neuronal and hormonal signals which are transduced over multiple pathways to the muscle genome. Exercise activates many signaling cascades–the individual characteristic of the stress leading to a specific response of a network of signaling pathways.
