BIX-A1043 Guide: 85cm Both Sex Torso Model, 40 Parts — Full-Size Anatomy Torso with Organs

Product Description

Educational-use note: anatomical teaching model — educational equipment, not a medical device. Request the specification sheet by email for finishes and options.

1. Full Size, 40 Pieces: Two Decisions That Change What You Can Teach

A torso model makes three choices for you: how big it is, how deep it goes, and which patient it represents. The A1043 answers all three: 85 cm, 40 pieces, both sexes in one model.

Size is not vanity. Among 380 students with no prior anatomy knowledge, those studying from models whose longest diameter exceeded 10 cm recalled significantly more anatomical names than those using smaller models (F(2,707) = 17.15, p < 0.05) (Yang et al., 2023). In a lecture hall, size also decides whether the back rows can see the relationship being described.

Physical beats screens — measurably. Students naming structures on a cadaver pelvis scored 67% (with haptic feedback) and 69% (without) using a physical model, versus 41% using three-dimensional visualisation technology (p < 0.0001); in the transfer test the model scored 74% against 43%, an advantage attributed mainly to stereoscopic vision (Wainman et al., 2018).

Physical models also equalise. In a 78-student crossover study there was no overall VR-versus-model difference, but learners with low visuospatial ability performed significantly worse with VR (p = 0.001 immediately; p = 0.003 at 48 hours), while on the physical model low and high ability groups performed similarly well (Wainman et al., 2021).

2. Evidence

3. What the 40 Pieces Let You Teach

A. Neuroanatomy that comes apart

The 8-piece brain and 4-piece spinal nerves turn the nervous system into a build-and-identify exercise rather than a diagram — the content where physical modelling has been shown to lift scores specifically on three-dimensional questions (Estevez et al., 2010).

B. Thorax and abdomen, organ by organ

Four-part lungs, two-part heart, trachea/esophagus/aorta, diaphragm, liver, kidney, two-part stomach and four-part intestine allow a full dissection sequence in one session, the body wall opening around the organs instead of hiding them.

C. Two reproductive systems, one torso

Male reproductive organs (4) and female reproductive organs with fetus (3) sit in the same model, so students compare the two sets directly rather than studying them on separate models. The comparison is the learning objective, built into the hardware.

D. Obstetric and fetal teaching

The fetus piece supports antenatal teaching: fetal position, the uterus in relation to surrounding structures, and space constraints at term.

E. Lecture hall and small group

At 85 cm on its stand the A1043 is legible from the back of a teaching room; its 40-piece breakdown keeps it useful when the cohort splits into stations.

4. Where the A1043 Sits in the Torso Series

Buying logic: choose the A1043 when one model must serve both a lecture hall and detailed organ study, and the syllabus covers neuroanatomy, both reproductive systems and fetal position. Add 42 cm A1047 units if the course also needs multiple student stations.

5. Teaching Protocol (suggested)

Assessment checklist (suggested)

● Named the required structures on the intact torso

● Removed and reseated parts in order without forcing components

● Rebuilt the brain unlabelled

● Described one relationship between the male and female sets

● Reassembled the torso with all 40 pieces correctly seated

7. FAQ

Q1: What comes with the BIX-A1043? A: A 40-piece PVC torso on a plastic stand — the full component list is in the table above, from the 8-piece brain and 4-part spinal nerves to both reproductive sets, the female set including a fetus.

Q2: Why choose 85 cm over a 42 cm torso? A: Visibility and depth. Models above 10 cm longest diameter have shown better anatomy recall (Yang et al., 2023), and 85 cm is readable from the back of a lecture hall while 40 pieces still allow station work.

Q3: Does it cover both male and female anatomy? A: Yes — male reproductive organs (4) and female reproductive organs (3, with fetus) are both included, so the two systems can be compared in one session.

Q4: Is the fetus piece useful for teaching? A: It supports obstetric and maternal-child topics: fetal position, the uterus in relation to surrounding organs, and space constraints at term.

Q5: What is the MOQ and price? A: MOQ is 1 unit; price on request, varying with configuration and volume. Email ada-manikin@adaanatomy.com. for the quotation and spec sheet.

Q6: What are the delivery and service terms? A: Air freight 7–10 business days; sea freight 30–45 days. Manual included; spare parts on request — ada-manikin@adaanatomy.com..
