Vertebra Lumbar Spine Anatomical Model - Degenerative Changes Disc Protrusions Disassemblable 3B Scientific

H2: Vertebra Anatomical Model

The model provides a detailed representation of degenerative changes affecting the vertebral bodies and intervertebral discs in the lumbar spine, illustrating conditions across a spectrum of severity. Based on an original cast of a human lumbar spine, fine bony structures are accurately reproduced to support advanced anatomical education.

The sequence from top to bottom displays:

• Intervertebral disc in healthy condition
• Lumbar vertebra (L1) without degenerative changes
• 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, demonstrating pressure on the spinal nerve root L5 on the left

The model is designed for disassembly into individual vertebrae and intervertebral discs to facilitate hands-on learning.

Supplied on a stable base for secure display and classroom use.
