The erector spinae is a group of muscles located along the spine that primarily functions to extend and laterally flex the vertebral column. When activated, these muscles help maintain an upright posture and support movements such as bending backward or side to side. They also play a crucial role in stabilizing the spine during various activities, including lifting and twisting. Overall, the erector spinae is essential for spinal mobility and stability.
