A answered. Once the bacteria from a cat scratch reaches the blood stream, cat scratch disease (CSD) can spread to various parts of the body. Swollen lymph nodes closest to the scratch or bite are the most noticeable symptom. Most often these are the lymph nodes in the head, neck or upper limbs.
The upper three regions comprise the remaining 24, and are grouped under the names cervical (7 vertebrae), thoracic (12 vertebrae) and lumbar (5 vertebrae), according to the regions they occupy. Source(s): http://en.wikipedia.org/wiki/Vertebrae.
Lumbar (Definition). The lumbar part of the spine is the low back. It is made up of five bones (most of the time) stacked one on top of the other. They are connected by disks, facet joints, and ligaments. These soft parts allow for movement controlled by the spinal muscles; the muscles can also keep it stiff when need be.
