BIX-A2110 Guide: Teaching the Parasympathetic System as a Circuit
Short answer: The BIX-A2110 is an electric parasympathetic brain model measuring 56 × 12 × 66 cm. It is built to show the parasympathetic component of the brain — the cranial and vagal outflow that slows the heart, drives secretion and governs resting digestion. Because the display is electric, the pathway can be lit on the model while the teacher is talking about it, rather than described in the abstract.
Key takeaways
- Dedicated to one division of the autonomic nervous system, so the teaching message is not diluted
- Electric display: the parasympathetic route can be lit structure by structure
- Bench-scale at 56 × 12 × 66 cm — large enough for a lecture room, small enough for a lab bench
- Fits nursing, physiology and pre-clinical neuroscience courses
- Pairs naturally with a sympathetic counterpart so students compare the two divisions side by side

Why "rest and digest" has to be taught spatially
Autonomic physiology is routinely examined as a list of opposing effects. The trouble is that the two divisions are anatomically asymmetric — sympathetic outflow is thoracolumbar while parasympathetic outflow is cranial and sacral — and a list cannot convey that.
The brain is a network problem before it is a naming problem. The human connectome project describes the structural connection matrix of the brain as an indispensable foundation for basic and applied neuroscience, which is precisely the framing that a physical pathway model serves at undergraduate level [1]. And the format itself has support: the meta-analysis of comparative studies found measurable benefit for physical models in anatomy teaching [2], while the meta-analytic comparison of simulation-based education with deliberate practice showed better skill-acquisition results than traditional clinical teaching [3].
The practical consequence for a parasympathetic model is straightforward. A student should be able to light the pathway, state the cranial nerve involved, name the target organ, and predict the effect of stimulating it — in that order, out loud.
Running a session with the A2110
- Start with the asymmetry. Draw the sympathetic thoracolumbar outflow on the board, then light the parasympathetic route on the model. The contrast does the work.
- Cranial nerve drill. Work down the cranial nerves that carry parasympathetic fibres and ask for the target organ of each.
- Vagal emphasis. Spend the most time on the vagus, because its reach — heart, lungs, gut — explains most of the clinical pictures students will meet.
- Pair with pharmacology. For a nursing group, follow the anatomy with a short discussion of what happens when the pathway is blocked or stimulated.
- Use it as a station. In an OSCE-style circuit, five minutes at the model with three structured questions is a cost-effective station.
What to check before you order
- Power supply. The page does not list the voltage or plug type. Confirm the supply and plug standard for your country before ordering.
- Spare lamps or LEDs. Ask whether individual display elements can be replaced, since the electric function is the main reason to buy this model over a static one.
- Scope of labelling. Request the list of labelled structures so you can check it against your syllabus, especially the cranial-nerve detail.
- Price. This page does not publish a price; the unit is quoted on request.
FAQ
Q1. What is the BIX-A2110?
It is an electric brain model that shows the parasympathetic component of the brain, used to teach autonomic nervous system anatomy and physiology.
Q2. What size is the model?
56 × 12 × 66 cm.
Q3. What does "electric" mean on this model?
The display is electric, so the parasympathetic pathway can be lit on the model during teaching rather than only described.
Q4. Who is it designed for?
Nursing, physiology and pre-clinical neuroscience courses where the autonomic nervous system is taught in detail.
Q5. Should I also order a sympathetic model?
It is worth considering. Teaching the two divisions side by side is the most effective way to convey their anatomical asymmetry.
Q6. How do I get pricing, or confirm the power supply for my country?
Email chinonplus@adaanatomy.com with the model (BIX-A2110), the quantity you are considering, your destination port and your required plug standard; our export team will reply with pricing, lead time and configuration.

Email chinonplus@adaanatomy.com for the BIX-A2110 price list and shipping details. If your course covers the nervous system more broadly, the same brain range includes artery-and-nerve brain models and brainstem specimens, so a coherent neuroanatomy set can be specified in one order.
