ADA-209 55cm Torso, 20 Parts: Which Size Class Should You Actually Buy?

Short answer: ADA-209 is a 55 cm unisex torso that separates into 20 parts. The published parts list covers the torso shell, head, eyeball, brain, two-part lungs, two-part heart, liver, gallbladder, kidney, two-part stomach, two-part intestines, vertebra spinal nerves, and interchangeable male (2 parts) and female (2 parts) genitalia. The page lists a reference price of USD 81.04, subject to order quantity. Its real question is not "is 20 parts enough" but "which of the three size classes in this series fits my room".

Key takeaways

• 55 cm sits in the middle of the series — large enough for group demonstration, small enough to place several on one bench.
• Both genitalia sets are included, so one unit covers male and female reproductive teaching without buying twice.
• 20 parts means real disassembly, not a single lift-out block: lungs, heart, stomach and intestines are all multi-piece.
• Price is published at a USD 81.04 reference, which makes it directly comparable with the rest of the range.
• Certification shown on the page: ISO 9001, ISO 14001, ISO 45001.

The size class comparison

The same catalogue offers torsos at 26 cm, 55 cm and 85 cm. Below is the trade-off, stated plainly. Only the 55 cm unit is the subject of this article; the other rows exist so you can place it.

The rule that falls out of the table: pick the size class by how many students must see the model at once, then spend the remaining budget on quantity. A room with six small tables is usually better served by several 55 cm units than by one 85 cm unit, because more students get hands on the parts.

If you are placing the 55 cm class against a specific shelf or cabinet, write to chinonmed@adaanatomy.com with the model number ADA-209 and ask for the assembled footprint and the carton dimensions before you order, since the page does not print them.

What the 20 parts actually are

Two details are worth pulling out of that list. First, the gallbladder and the vertebra spinal nerves are both present — small structures that cheaper torsos often drop, and both are examinable. Second, the male and female genitalia are supplied as separate multi-part inserts rather than moulded in, which is why a single unit can serve both modules.

ADA-209 against the 85 cm 40-part torso: what you gain and lose

Why part count is not a quality score

A meta-analysis of comparative studies found physical models effective for teaching anatomy [1], and the systematic review of advances in anatomy education places physical models alongside virtual tables and 3D printing as complementary tools rather than competitors [2]. An evaluation of physical anatomical models in anatomy education reaches a similar position — the model type matters less than whether students can repeatedly handle and re-identify structures [3].

That last point is the practical one for a 20-part torso. Twenty parts, handled by eight students in rotation, teaches identification better than forty parts handled once by a lecturer. The honest limit of ADA-209 is that it does not show deep structures, sectional planes or pathology; for those, the series offers a sagittal-section torso and separate models.

FAQ

Q1. What is ADA-209?
A 55 cm unisex human anatomy torso model that separates into 20 parts, supplied with both male and female genitalia inserts.

Q2. How many parts exactly?
Twenty, comprising the torso, head, eyeball, brain, lung (2), heart (2), liver, gallbladder, kidney, stomach (2), intestines (2), male genitalia (2), female genitalia (2) and vertebra spinal nerves.

Q3. Does it include both male and female anatomy?
Yes — the page lists male genitalia (2 parts) and female genitalia (2 parts) as separate components of the same model.

Q4. How does 55 cm compare with the 85 cm and 26 cm versions?
The 26 cm class suits desk study, the 55 cm class suits small-group teaching, and the 85 cm class suits whole-class demonstration. Visibility and units-per-budget move in opposite directions.

Q5. What does it cost?
The page lists a reference price of USD 81.04, subject to the quantity of the order.

Q6. What is not published?
Package size, weight and material data. Email chinonmed@adaanatomy.com with the model (ADA-209) and your quantity, and ask for the unit price, carton dimensions and material in the same message.

Request a quotation

Write to chinonmed@adaanatomy.com for the ADA-209 specification sheet and a quotation. If you are buying for several rooms, say so in the enquiry: the series is priced subject to order quantity, and ordering the small-group and full-class units together is normally the cheapest way to cover a whole teaching floor.
