Verified step by step guidance1
Begin by understanding the primary function of each type of tissue mentioned in the problem. Epithelial tissue is known for covering and lining surfaces, both internal and external, which is a key characteristic to focus on.
Consider the location and role of epithelial tissue in the body. It forms the outer layer of skin and lines organs and cavities, providing protection and selective permeability.
Compare epithelial tissue with connective tissue, which primarily supports, binds, and protects tissues and organs, but does not cover surfaces in the same way.
Evaluate nervous tissue, which is specialized for communication and control through electrical impulses, and muscle tissue, which is responsible for movement. Neither of these tissues primarily covers surfaces.
Conclude that epithelial tissue is the type that covers internal and external body structures, based on its defining characteristics and functions.
