Verified step by step guidance

Step 1: Understand the structure of a nerve. A nerve is composed of multiple bundles of axons (nerve fibers) organized into fascicles, which are surrounded by connective tissue layers.

Step 2: Learn the hierarchy of connective tissue layers in a nerve. The innermost layer is the Endoneurium, which surrounds individual axons. The middle layer is the Perineurium, which encloses fascicles (bundles of axons). The outermost layer is the Epineurium, which encloses the entire nerve.

Step 3: Differentiate between the terms provided in the question. The Perineurium surrounds fascicles, the Perimysium is related to muscle tissue (not nerves), the Endoneurium surrounds individual axons, and the Epineurium encloses the entire nerve.

Step 4: Recognize that the dense irregular connective tissue layer enclosing the entire nerve is the Epineurium, based on its anatomical function and location.

Step 5: Confirm the correct answer by matching the description in the question to the function of the Epineurium, which is to provide protection and structural support to the entire nerve.
