Verified step by step guidance
1
Step 1: Understand the function of the tissue types listed in the problem. Epithelial tissue is specialized for lining body cavities and covering external surfaces, connective tissue provides support and structure, nervous tissue is involved in communication and control, and muscle tissue is responsible for movement.
Step 2: Recall the characteristics of epithelial tissue. It forms continuous sheets of cells that act as a protective barrier, and it is found lining organs, body cavities, and the external surface of the body.
Step 3: Compare the functions of epithelial tissue with the requirements of the problem. The problem specifies tissues that line body cavities and cover the external surface, which matches the role of epithelial tissue.
Step 4: Eliminate the other options based on their primary functions. Connective tissue does not line cavities or cover surfaces, nervous tissue is involved in signaling, and muscle tissue is responsible for contraction and movement.
Step 5: Conclude that epithelial tissue is the correct answer based on its unique role in lining and covering surfaces.
