What action does the multifidus have in common with the erector spinae?

The Erector Spinae muscle actually consists of three columns of muscles, the Iliocostalis, Longissimus, and Spinalis, each running parallel on either outer side of the Vertebra and extending from the lower back of the skull all the way down to the Pelvis.
The multifidus muscle is a series of small, triangular muscle bundles located on either side of the spinal column that make up the 2nd layer of the deep back muscles. Composed of 3 layers total, the deep back muscles are collectively called the intrinsic layer. Yet another name for this group is the transversospinal layer.
Above the transversospinal (deep) layer of back muscles is the superficial layer.The superficial layer is also known as the extrinsic muscles or the "erector spinae," or simply the paraspinal muscles.
The multifidus stabilizes the spine and helps the erector to move it.

What is the result of bilateral contraction of the erector spinae group?
Bilateral contraction of the erector spinae muscles which are the iiliocostalis, longissimus and spinalis leads to extension/hyper extension of the back.
What muscle extends the vertebral column?
Iliocostalis Thoracis
Muscle spasms of the back often are due to the erector spinae contraction?
True.
What movement does an asymmetrical contraction of the erector spinae produce?
Lateral bending of the spine.
What is the antagonist of cervical erector spinae?
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!
