True.
An asymmetrical contraction of the erector spinae muscles can result in lateral flexion of the spine, where the spine bends to one side.
Bilateral contraction of the erector spinae group results in extension of the spine, helping to maintain an erect posture and stabilize the vertebral column during activities like standing and lifting.
Erector Spinae are extensor muscles encompasing the neck and trunk. Extensor movement is antagonistic to flexor movement. Therefore, find a muscle of the neck and a muscle of the trunk that act as flexors. That should answer your question without giving away all of the milk and honey!
The erector spinae muscles are responsible for extending the vertebral column. They run along the spine and help to maintain posture and assist in movements like bending backward or standing upright.
