Short answer: The BIX-A18102 is an anatomy model that shows the brain, the cerebral nerves, the spinal cord and the spinal nerves as one connected system, with 47 positions displayed. It is moulded in advanced PVC and hand-painted, and it belongs to the Torso Series in the Medical Series line. Its teaching value is simple: most classroom models show the vertebral column as bone, leaving the cord itself — the structure that determines neurological outcome — invisible inside the canal. This model opens that canal.
Key takeaways
| System shown | Teaching use |
|---|---|
| Brain | Cranial structures and the origin of the cerebral nerves |
| Cerebral nerves | Cranial nerve sequencing and their targets |
| Spinal cord | Cord segments and their position inside the vertebral canal |
| Spinal nerves | Segment-by-segment relationship between cord level and nerve exit |
| 47 positions | Ready-made checklist for spot tests and viva questions |
Human anatomy is a foundational course in nursing curricula, and the reason students find it hard is structural rather than motivational: the subject is built from complex spatial relationships and dense content, which produces a high cognitive load. A 2026 randomised controlled trial published in BMC Medical Education opens with exactly that framing when it evaluates a blended anatomy teaching model for nursing students [1]. A model that physically exposes a structure normally hidden inside a bony canal is a direct answer to that problem — the cord-to-nerve-level relationship stops being a memorised table and becomes a spatial fact.
The wider evidence supports physical models in general. Yammine and Violato's meta-analysis in Advances in Health Sciences Education (2016), covering 8 studies (7 randomised), 16 comparison arms and 820 learners, found that physical anatomical models gave better factual and spatial knowledge outcomes than comparator teaching methods [2].
Spinal cord anatomy also carries clinical weight that students can feel early. A 2026 integrative review in Frontiers in Medicine describes spinal cord injury as a major global health challenge associated with significant physical, psychosocial and economic consequences, and examines how nursing interventions shape rehabilitation, autonomy and quality of life [3]. Students who can name the level, the segment and the nerve are better equipped to understand why a lesion at one level produces deficits at a specific distribution — which is precisely the conversation that follows a spinal injury on a ward.
The product page lists the model number, the two features reproduced above — the systems shown and the 47 displayed positions — and states the materials as advanced PVC and paint.

Q1. What does the BIX-A18102 show?
The brain, cerebral nerves, spinal cord and spinal nerves, with 47 positions displayed.
Q2. How is it different from a spine model?
A spine model shows bone. This model shows the nervous structures — the cord inside the canal and the spinal nerves — which is what determines neurological function.
Q3. What materials is it made from?
Advanced PVC with painted detailing.
Q4. How can the 47 positions be used in class?
As a structured checklist: point to a position and ask the student to identify the structure and its relations, or use it for viva and spot-test practice.
Q5. Which courses is it suited to?
Nursing and medical anatomy modules, neuroanatomy teaching, physiotherapy and rehabilitation programmes.
Q6. How do I obtain the price and documentation?
Email adanursing@adaanatomy.com with the model (BIX-A18102), the quantity and the destination country. We will send pricing and the available documentation.
Email adanursing@adaanatomy.com for the BIX-A18102 quotation. Nursing schools often pair this model with a coronal-section torso (BIX-A3009) and a muscle torso (ADA-210) so one order covers anatomy, neuroanatomy and surface anatomy teaching — ask us for a combined price.
