Lumbar fascia Lumbar fascia The lumbar fascia is an anatomic structure of the lumbar region. It consists of a band or sheet of connective tissue fibres, primarily collagen, that attaches, stabilizes, encloses and separates muscles not limited to the lumbar region as the name suggests, but extending upwards over the thorax to the neck and downwards over the muscles covering the sacrum. The upper thoracic portion is thin while the lumbar and sacral regions are thicker and stronger. The lumbar fascia binds the deep muscles of the back to the spine and to the transverse processes of the vertebrae. Additionally the lumbar
Spindle cell sarcoma Spindle cell sarcoma Spindle cell sarcoma is a type of connective tissue cancer in which the cells are spindle-shaped when examined under a microscope. The tumors generally begin in layers of connective tissue such as that under the skin, between muscles, and surrounding organs, and will generally start as a small lump with inflammation that grows. At first the lump will be self-contained as the tumor exists in its stage 1 state, and will not necessarily expand beyond its encapsulated form. However, it may develop cancerous processes that can only be detected through microscopic examination. As such, at this level
