In the I Love Spaghetti mnemonic, which muscle is the most medial?

Explanation:
The I Love Spaghetti mnemonic helps you recall the erector spinae muscles from outside to inside: iliocostalis is the most lateral, longissimus sits in the middle, and spinalis runs closest to the spine. Therefore, the most medial muscle is spinalis, the one positioned right along the midline next to the spinous processes. This placement aligns with its role in extending and stabilizing the vertebral column, especially in the thoracic and upper lumbar regions.
