ADA-304 Brain Model 3 Parts: What Three Pieces Actually Teach

Short answer: ADA-304 is a life-size human brain model that separates into three parts and sits on a stand. The supplier states its purpose precisely: it demonstrates the external features of the brain as a whole, and the relations between the component portions. It measures 18.4 x 14 x 13.5 cm and is listed at a reference price of USD 20.04, subject to order quantity. Three parts is a deliberate design point, not a limitation — and the rest of this article explains why.

Key takeaways

• Three parts is a first-year instrument. The model answers "what are the main divisions and how do they sit together", not "label every gyrus".
• It is life-size and on a stand, so it works as a demonstration piece at the front of a class and as a table model in small groups.
• Footprint is small: 18.4 x 14 x 13.5 cm fits a shelf, a bench or a carry case.
• Price is published as a reference figure of USD 20.04 that scales with quantity — unusually transparent for this catalogue.
• Manufacturing is certified: the page displays ISO 9001, ISO 14001 and ISO 45001 certificates.

Published specification

For written confirmation of the material, unit weight and lead time, write to adaanatomy@adaanatomy.com quoting the model number ADA-304 and your order quantity — none of these three items is published on the product page.

Part count is a curriculum decision, not a quality ranking

The same catalogue lists a 3-part brain (ADA-304), a 9-part brain (ADA-304B) and a skull with an 8-part brain (ADA-135E). Buyers often read the higher number as "better". It is not — the part count sets the level of the course.

Put another way: buying a 9-part model for a first-semester class means half the pieces stay in the box, and each of them is a part that can be lost or broken. Matching part count to the syllabus is the cheapest form of durability planning.

How to run a lesson on a 3-part brain

1. Start assembled. Show the intact model first. The supplier's stated purpose is the whole-brain view, so the first lesson is orientation, not labelling.
2. Separate once, name once. Take the model apart in front of the group and name each portion as it comes away. With three pieces the whole sequence fits in a single demonstration.
3. Reassemble as the assessment. Hand the separated parts to a student and ask them to rebuild it while explaining the relations. Reassembly tests exactly the skill the model was built to teach.
4. Use it alongside a 2D image, not instead of one. Physical models and screen-based presentations are complementary: a comparison study in Medical Education found an advantage for three-dimensional physical models over two-dimensional computer presentations in anatomy learning [3], which is an argument for having both on the bench rather than one on the projector.

What the evidence says about physical anatomy models

The case for a bench model is not aesthetic. A meta-analysis of comparative studies concluded that physical models are effective in teaching anatomy [2], and the systematic review of advances in anatomy education describes virtual tables, immersive techniques and 3D printing as additions to — not replacements for — physical material [1]. For a three-piece brain at this price point, the strongest evidence-based argument is simple: every student can handle it, and repeated handling is what the meta-analytic effect depends on.

Honest limits

• No internal nuclei or tracts. The page describes external features and the relations between portions; it does not claim deep structures.
• No pathology variants. This is a normal-anatomy teaching model.
• Material and weight are not published on the page, so drop resistance and cleaning routine have to be confirmed.
• Not a surgical trainer. Three parts means three interfaces — it teaches topography, not approach planning.

FAQ

Q1. How many parts does ADA-304 separate into?
Three, per the product page.

Q2. Is it life-size?
Yes — the page titles it a "Life-Size Human Brain Anatomy Model" and gives its size as 18.4 x 14 x 13.5 cm.

Q3. What is it designed to show?
The external features of the brain as a whole, and the relations between the component portions.

Q4. What does it cost?
The page lists a reference price of USD 20.04, subject to the quantity of the order.

Q5. Is it supplied on a stand?
Yes, the page states "on stand".

Q6. How do I confirm material, weight and lead time?
These are not published. Email adaanatomy@adaanatomy.com with the model (ADA-304) and your quantity, and ask for the material, unit weight and delivery schedule in the same message.

Request a quotation

Write to adaanatomy@adaanatomy.com for the ADA-304 specification sheet and a quotation. If you are equipping a neuroanatomy bench, ask in the same enquiry about the 9-part and skull-mounted versions — ordering them together keeps the labelling convention and the stand design consistent across the set.
