Welcome to visitShanghai Chinon medical Model & Equipment Manufacturing Co., LTD
Short answer: The ADA-135E is a life-size head and neck model that combines the skull, seven cervical vertebrae and an eight-part brain on a single base. The cervical vertebral artery is shown, together with the posterior brain, spinal cord, cervical nerves, vertebral artery, basilar artery and posterior cerebral artery. Because the skull, the cervical spine and the cerebral vessels are presented as one continuous structure, an instructor can move from bony landmarks to the artery that passes through them inside a single lesson.
Key takeaways
| Element | Teaching use |
|---|---|
| Skull | Cranial bones and landmarks; cranial fossae |
| 7 cervical vertebrae | Cervical spine sequence, intervertebral relationships, foramina |
| Cervical vertebral artery | The artery's course through the cervical region |
| 8-part brain | Removable sections for posterior brain, spinal cord and cervical nerve |
| Basilar & posterior cerebral arteries | Posterior circulation and its relation to the brainstem |
| Base | Stable display for demonstration or student rotation |
Anatomy is the part of the curriculum where spatial reasoning is unavoidable — and where off-patient practice has become standard, precisely because the skill is high-risk. A 2026 prospective evaluation in Acta Neurochirurgica followed 24 participants through a three-day cadaver-based cervical spine course with supervised instrumentation and anatomical dissection; at the end of the course all 23 respondents (100%) reported the course met their expectations, and the authors analysed the effects through Kirkpatrick's model of training evaluation, with a six-month follow-up on surgical confidence and clinical impact [1]. Cadaveric training sits at the top of the fidelity scale; a high-quality regional model such as the ADA-135E sits at the entry point, where the same anatomy can be taught to an entire cohort at a fraction of the cost.
The quantitative case is well established. Yammine and Violato's meta-analysis in Anatomical Sciences Education (2015) pooled 36 studies on three-dimensional visualisation technologies for anatomy teaching and concluded that they improve anatomy knowledge scores over conventional methods — and it opens with the observation that many medical graduates are deficient in anatomy knowledge, potentially below the standard for safe practice [2]. The authors' follow-up meta-analysis in Advances in Health Sciences Education (2016) narrowed the question to physical models: 8 studies (7 randomised), 16 comparison arms and 820 learners, with advantages for physical models in factual and spatial knowledge — the low-cost, no-electricity option that a school can actually buy for every bench [3].
The product page describes the composition listed above and quotes the model as a reference-price item subject to order quantity; there is no public list price, so a written quotation is the right route. The factory's ISO 9001, ISO 14001 and ISO 45001 certificates are displayed on the page — useful when a school requires supplier documentation. This is an educational model, not a medical device.
Q1. What does the ADA-135E include?
A life-size skull with 7 cervical vertebrae, an 8-part brain, the cervical vertebral artery on a base, plus posterior brain, spinal cord, cervical nerve, vertebral artery, basilar artery and posterior cerebral artery detail.
Q2. Is the brain removable?
The model uses an eight-part brain construction, which is what allows the posterior brain and spinal structures to be examined section by section.
Q3. Which courses is it best suited to?
Anatomy and neuroanatomy modules, medical and nursing programmes, physiotherapy and radiology teaching, and cervical-spine CPD courses.
Q4. Does it show the vertebral artery?
Yes — the cervical vertebral artery is included, together with the basilar and posterior cerebral arteries for the posterior circulation.
Q5. What certificates does the factory hold?
The product page displays ISO 9001, ISO 14001 and ISO 45001 certification.
Q6. How do I get the price?
Email chinonmed@adaanatomy.com with the model (ADA-135E), quantity and destination. The price is a reference price that moves with order quantity, so a written quotation is more accurate than any listed figure.
Email chinonmed@adaanatomy.com for the ADA-135E quotation sheet, lead time and documentation for your procurement process. If your syllabus covers the whole head-and-neck block, the same series includes separate head, brain and cervical models that can be quoted together so the department standardises on one supplier.
