Spine and Vertebrae Models

These represent different spinal levels with varying detail: BS 28 covers lumbar/thoracic vertebrae with the spinal cord's nerve endings, filum terminale, and cauda equina; BS 29 is a cervical vertebra showing spinal nerves, ganglion, and vertebral artery; BS 30 is an enlarged (7×) cervical vertebra with more extensive nerve and vascular detail. If you're teaching spinal nerve pathways specifically, BS 30's enlargement may be worth the added cost over the natural-size BS-series options — let us know your course level and we can compare.

QS 15-N is articulated on nylon, while the standard QS 15 uses a different articulation method (typically wire or elastic core). Nylon articulation tends to hold position better for display purposes but may flex differently than wire-core models during movement demonstrations — worth specifying based on whether your primary use is static display or dynamic posture teaching.

Yes — the QS 8 series comes in multiple configurations (14-part, 18-part, colored/uncolored, with or without the "+M" muscle of mastication addition). The suffix indicates the exact configuration, so if you're standardizing across multiple lab stations, confirm the full model number rather than just "QS 8" when reordering.

QS 17 vertebrae are available as individual selections (cervical, thoracic, or lumbar) rather than requiring a full set purchase — useful if you only need a representative sample of each region rather than duplicating what's already in a complete spine model.

Flexible spines allow physical repositioning for teaching posture, movement, and biomechanics — useful for hands-on kinesiology or manual therapy instruction. Rigid/mounted spines hold a fixed anatomical position and are generally more durable for repeated handling in a classroom setting where movement demonstration isn't the primary goal. If your program does both lecture-based landmark ID and hands-on movement work, some departments order one of each rather than compromising on a single model.

This depends on the specific configuration — some multi-part combination models may have individually available replacement sections, while others are sold as a single molded unit. Send us the exact model number and we'll confirm what's separately replaceable.

Pathology models (disc herniation, osteoporosis, compression) tend to be lower-volume, made-to-order items with longer production timelines than standard anatomy teaching spines. If you're working against a funding deadline, check availability on pathology-specific models before committing to a purchase timeline.

Yes — we regularly build combined quotes spanning spine, pelvis, and skull collections so a full lab setup (e.g., outfitting a chiropractic or PT program) ships together under one order rather than as separate purchases.

Yes — we offer repair and support for SOMSO anatomical models, including models purchased elsewhere. If a model in your existing lab inventory is damaged from too much student love, contact us for an assessment before assuming it needs full replacement. Please click here for more information.

Model numbers are usually stamped on the base or mounting stand. If unavailable, send photos showing the vertebra's shape, region (cervical/thoracic/lumbar), and any visible nerve/artery detail, and we can help identify the closest match from the manufacturer's line.
