Short answer: ADA-308D is a life-size brain model, dissectible into nine numbered parts and mounted on a stand, whose specific purpose is stated on the product page: understanding the correlation of the brain's parts, with the cerebral hemisphere, brain stem and cerebellum as the external landmarks. The comparison that matters is against the simpler three-part brain models in the same catalogue. Choose by how many relationships you need to show — not by which model has more parts.
Key takeaways
| Criterion | 3-part brain model | ADA-308D (9 parts) |
|---|---|---|
| Published separation | Three blocks — typically hemisphere, cerebellum, brainstem | Nine numbered parts |
| Teaching objective | The overall concept of the brain and the relationships between its major divisions | Understanding the correlation of brain parts, with the same major divisions as the external frame |
| Vessels | Not part of the configuration | Modelled as "brain with arteries" |
| Handling in class | Fast to reassemble; suits introductory sessions | More parts to track; suits sessions where internal relationships are the objective |
| Footprint | Comparable | 18.5 × 14 × 13.5 cm, on a stand |
| Price signal | Lower tier | USD 40.66 listed, subject to order quantity |
| Item | Published value |

If your assessment asks a student to name structures, a three-part model is enough. If it asks a student to explain how structures sit relative to one another, you need the extra separation. The evidence for the physical model's role is about exactly this: spatial relationships. A randomised comparison found three-dimensional physical models outperformed two-dimensional computer presentations in anatomy learning [1], and a meta-analysis of comparative studies reached the same general conclusion for physical models in anatomy teaching [2]. Neither result says "more parts is better" — both say the physical object is doing work that a flat image cannot.
Applied to this choice: buy the nine-part model when the lesson is about correlation, and buy the three-part model when the lesson is about orientation. Buying nine parts for an orientation class adds handling time and no teaching value.
The same Brain Models category shows the alternative configurations, so the comparison can be made inside one supplier:
| Option in the same series | Published separation |
|---|---|
| ADA-308D Brain with Arteries | 9 parts, life-size, numbered, on stand, with cerebral vessels |
| ADA-304B New Style Brain Model | 9 parts |
| ADA-304A New Style Brain Model | 3 parts |
If a department wants one demonstration model and one set of student models, the usual configuration is the higher-part model for demonstration and the lower-part model for bench work — the same teaching objective, two different jobs.
| Not stated on the page | Why you need it |
|---|---|
| Painted or numbered by structure across all nine parts | Determines whether colour is used as an additional teaching cue. |
| Whether vessels are painted or modelled in relief | Affects how visible the arterial supply is in a lecture room. |
| Single-unit carton dimensions and gross weight | The page gives the multi-unit carton; single-unit data is needed for a small order. |
| Price at your order quantity and lead time | Listed price is explicitly subject to order quantity. |

Q1. What is ADA-308D?
A life-size brain model with arteries, dissectible into nine numbered parts and mounted on a stand, showing the cerebral hemisphere, brain stem and cerebellum as external features.
Q2. What is the difference from a 3-part brain model?
A three-part model separates the major divisions. ADA-308D separates nine parts, so internal relationships between structures can be shown rather than only named.
Q3. What size is it, and what is the carton data?
Size 18.5 × 14 × 13.5 cm. Packing is published as 18 pcs per carton, 53 × 39 × 55 cm, 17 kg.
Q4. What is it made of?
PVC, per the product page.
Q5. Is the price published?
The site lists USD 40.66, subject to order quantity. Confirm the price for your volume before ordering.
Q6. How do I request the specification and a quotation?
Email adacpr@adaanatomy.com with the model (ADA-308D) and the detail you need — painting scheme, vessel modelling, single-unit carton data or price.
Write to adacpr@adaanatomy.com for the ADA-308D specification sheet and a quotation. If you are deciding between the nine-part and three-part configurations, say so in the enquiry and ask for both prices at your volume — that is the only way to compare the two tiers on real numbers.
