Lumbar Disc Herniation Model — 1.5x magnified L4L5 for clear demonstration What this model does Shows how the intervertebral disc shifts and herniates when the body is bent and curled, making the distribution of disc material and nerve relation easy to observe. Includes the fourth and fifth lumbar spinal nerves and intervertebral discs at 1.5 times natural size for improved visibility during demonstrations. The intervertebral disc is made of a soft elastic material that can be manipulated to simulate herniation and nerve compression. Key benefits Improves understanding by making internal structures visible and easy to explain during lessons or consultations. Practical for handson demonstrations because the elastic disc responds to pressure and movement for realistic representation. Lightweight and portable for use in classrooms, clinics, or lecture halls. Important attributes Function: Anatomical demonstration of lumbar disc behavior under flexion and curl positions. Coverage: Fourth and fifth lumbar spinal nerves and corresponding intervertebral discs (L4L5). Size: 1.5 times natural size for clear observation. Material: Soft elastic intervertebral disc for manipulation; anatomically accurate construction closely matching real human structure. Performance: Realistic visual and tactile response that supports demonstration and explanation without complex setup. Use scenarios Anatomy and physiology classes: Demonstrate lumbar mechanics and disc herniation patterns during lectures and lab sessions. Clinical education and patient consultation: Show patients how bending and posture influence disc position and nerve relation to support education and informed discussion. Physical therapy and rehabilitation training: Practice visual explanation of lumbar movement and illustrate how mechanical stresses affect the L4L5 region. Why choose this model Combines anatomical accuracy with a manipulable soft disc and enlarged scale to make complex lumbar relationships clear and accessible for students and professionals who need a reliable teaching aid.
