explain how the four major tissue types – epithelial, connective, muscular, and nerve – work together in the human arm.

Epithelial tissue, connective tissue, muscular tissue and nerve are present in all the body.

Explanation:

The major function of epithelial tissue is to provide protection to the muscles. The function of connective tissue is to connect with the bones to the muscles. The muscular tissue also helps in the movement of muscles. The whole movement is controlled by nerve through brain.

The brain gives direction through the nerve for the movement of arms. Then through muscular tissue the movement of muscles and bones are done. The epithelial tissue is present on the outer and inner lining of the skin.
