middle
Verified step by step guidance1
Understand the structure of a nerve: Nerves are composed of bundles of axons surrounded by connective tissue layers. These layers include the epineurium, perineurium, and endoneurium.
Learn the hierarchy of connective tissue layers: The epineurium is the outermost layer, the perineurium is the middle layer, and the endoneurium is the innermost layer.
Focus on the perineurium: The perineurium surrounds fascicles, which are bundles of axons within the nerve. It provides protection and maintains the internal environment of the fascicles.
Compare the options provided: The perineurium is not the outermost (epineurium) or innermost (endoneurium) layer. It is the middle layer.
Conclude that the correct answer is 'middle' based on the anatomical structure and function of the perineurium.
