Verified step by step guidance
1
Understand the structure of a nerve: A nerve is composed of multiple nerve fibers (axons) bundled together.
Identify the different connective tissue wrappings: Nerves have three main connective tissue layers - endoneurium, perineurium, and epineurium.
Define each connective tissue layer: The endoneurium surrounds individual nerve fibers, the perineurium encases a bundle of nerve fibers (fascicle), and the epineurium wraps around the entire nerve.
Focus on the epineurium: The epineurium is the outermost layer that provides protection and support to the entire nerve, including all its fascicles and blood vessels.
Conclude that the connective tissue wrapping that surrounds the entire nerve is the epineurium, based on the definitions and structure of nerve connective tissues.
