Model, Vertebral, Degeneration, 5 Stages - Me

The graphic, comparative model illustrates degenerative changes to the vertebrae and intervertebral discs of the lumbar spine in various degrees. Based on the original cast of a human lumbar spine, even finest bone structures are accurately depicted. The following conditions are shown from top to bottom: Intervertebral disc in healthy condition - Healthy lumbar vertebra (L1) - Intervertebral disc with protrusion - Lumbar vertebra (L2) with beginning degenerative changes - Intervertebral disc with medial prolapse - Lumbar vertebra (L3) with advanced degenerative changes - Intervertebral disc with intraforaminal prolapse on the right - Lumbar vertebra (L4) with strong degenerative changes and bony constriction of the left intervertebral foramen - Extremely narrowed intervertebral disc - Lumbar vertebra (L5) with strong degenerative changes and bony constriction of the left intervertebral foramen with pressure on the spinal nerve root L5 on the left. Measures 8-5/8". The model can be disassembled into vertebrae and intervertebral discs. Supplied on base.
