Epithelial tissue cells are tightly packed and form a continuous sheet. They have minimal intercellular spaces and are held together by small amounts of cementing material.
How are epithelial tissue cells arranged, and what is their characteristic feature regarding intercellular spaces?

Epithelial tissue cells are tightly packed and arranged in continuous sheets, forming a protective barrier on body surfaces and lining internal organs. Their characteristic feature is the presence of minimal intercellular spaces, thanks to specialized junctions like tight junctions and desmosomes. This arrangement ensures close cell-to-cell contact, enhancing barrier function and facilitating selective permeability.
