What are the erector spinae muscles What is its origin and insertion?
Since the erector spinae consist of nine separate muscles, there are many points of origin and insertion. In general, these muscles originate from the lumbar and lower thoracic regions of the body, and they insert onto the upper thoracic and cervical regions of the body.
Is the erector spinae a core muscle?
Your erector spinae is a vital part of your core, as it links to your abdominal and oblique muscles, which stabilizes and helps you move your entire upper body. Note: Your erector spinae is also referred to as, sacrospinalis group of muscles, spinal erectors, and most commonly, your lower back muscles.

What are the 7 core muscles?
The “core muscles,” which are the muscles responsible for giving us strength and stability when bending or twisting, can essentially be broken down into seven different sets: the rectus abdominis, the external obliques, the internal obliques, the transversus abdominis, the multifidus, the quadratus lumborum and the …

- Obliques.
- Transverse abdominis.
- Multifidus.
What are the 4 major core muscles?
The global movers/muscles include: Rectus abdominis. External obliques. Erector spinae.
Is erector spinae a core muscle?
Core Muscle Group: Erector Spinae These core muscles, aka the back extensors, allow you to extend your trunk, such as rolling up from a forward fold or bending backward into a bridge, according to ACE. One side of the erector spinae also works with the obliques and rectus abdominis to allow for lateral trunk flexion.
Where are the trap muscles?
The trapezius is one of the broadest and most superficial (closest to the skin) muscles of the upper back and trunk, meaning upon dissection of a cadaver it is often used as a landmark because it is encountered first. This muscle is triangular, broad, and thin and covers the upper back of the shoulders and neck.
What muscles make up the erector spinae group?
The iliocostalis muscles are the most lateral components of the erector spinae group. This subgroup includes the iliocostalis cervicis, iliocostalis thoracis, and iliocostalis lumborum.
What is the most lateral erector spinae muscle?
The iliocostalis muscles are the most lateral erector spinae muscles. According to their attachments and location, they are regionally divided into three groups, from superior to inferior: Iliocostalis colli muscle originates from the angle of ribs 3 to 6 and inserts into the transverse processes of vertebrae C4-C6.
Where are the erector spinae located?
They extend on either side of the vertebral column, between the base of the cranium superiorly and pelvis inferiorly. The erector spinae are divided into three groups, from medial to lateral:
Which posture causes the erector spinae to contract?
Poses where the erector spinae muscles contract: Postures such as shalabhasana will cause all of the erector spinae muscles to contract and lift the spine into hyperextension. In urdhva dhanurasana, we use the erector spinae muscles to concentrically contract against the resistance of both gravity and the front of the body.
