Lymph nodes are generally circular, bean-like organs that are dispersed throughout the body. The lumbar lymph nodes are located in the region of the body between the diaphragm (a muscle in the lower rib cage that helps with breathing) and pelvis, known as the lumbar region. They are also called the lateral aortic lymph nodes. The nodes are part of the lymphatic system of the human body.
Erector Spinae Muscles Anatomy. As you can see from the picture, the lower back is made up of the erector spinae muscles (also known as extensor spinae) that run alongside the entire length of the spinal column (from the base of the spine all the way to the neck bones).his muscle group can also be referred to as the lower back, even though it extends above that area. Well-developed spinal muscles make you look as if you have two boa constrictors running up your back. The muscles of the erector spinae attach to the vertebrae, the ribs, and the pelvis.
