The longissimus muscle is not one muscle, but a collection of three separate muscles that run up nearly the entire length of both sides of the spinal column, from the lower back up to the neck. These three muscles include:
- Longissimus capitis
- Longissimus cervicis
- Longissimus thoracis[1]
Longissimus belongs to the intermediate column of the Sacrospinalis group of muscles.[2]
