Longissimus is the longest, thickest and most central erector spinae muscle. It is divided into three parts (capitis, cervicis, thoracis) based on their superior attachments and location. The erector spinae muscles, including longissimus, are the most powerful extensors of the vertebral column.
Longissimus. 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.
Discover the function and structure of the longissimus capitis muscle, its origin and insertion points, and its role in head movement.
The longissimus capitis (trachelomastoid muscle) lies medial to the longissimus cervicis, between it and the semispinalis capitis. It arises by tendons from the transverse processes of the upper four or five thoracic vertebrae, and the articular processes of the lower three or four cervical vertebrae, and is inserted into the posterior margin ...
