Sympathetic nerve

A slender pale yellow to yellow-beige sympathetic autonomic nerve fiber or small nerve bundle shown isolated in a clean schematic anatomical clipart style. The main structure is an elongated, gently curving and slightly wavy thread-like cord with a smooth subtle outer sheath and a faintly beaded or segmented appearance from small varicosities or swellings along its length. Fine branchlets and delicate arborizing offshoots extend from the main trunk, especially toward the ends, tapering into thin terminal branches with small terminal bulbs or boutons. No surrounding tissue is shown.
