Correct answer: ASkin / subcutaneous fat / supraspinous ligament / interspinous ligament / ligamentum flavum

Midline approach: skin / subcutaneous fat / supraspinous ligament / interspinous ligament / ligamentum flavum / epidural space. The ligamentum flavum provides the characteristic loss of resistance. In the paramedian approach the supraspinous and interspinous ligaments are bypassed.
