which of the following is the most medial muscle group of the erector spinae group?
longissimus group muscles
splenius group muscles
iliocostalis group muscles
spinalis group muscles

Explanation:

The erector spinae group is a set of muscles that straighten and rotate the back. The spinalis group muscles are the most medial (closest to the midline of the body) within the erector spinae group. The longissimus group is intermediate in position, the iliocostalis is the most lateral, and the splenius is not part of the erector spinae group but rather a superficial back muscle.

Answer:

Spinalis Group Muscles
