Denoyer-Geppert 3-D Human Motor Neuron Model
The Denoyer-Geppert 3-D Human Motor Neuron Model (Product Code: SLE/A/152) is a diorama that reproduces a motor nerve cell at more than 2,500 times life size against a colour backdrop of associated neurons, and follows its axon all the way to the neuromuscular junction on a skeletal muscle. Physiology, neuroscience, pharmacology and sports-science departments use it to connect nerve-cell structure with how muscles are made to contract. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a biology lab instruments supplier.

Typical Use
Most neuron models stop at the cell itself; this diorama carries the story through to its effect. Students can start with the dendrites and synapses receiving input, look at the organelles in the cell body, follow the myelinated axon past a node of Ranvier, and then see several axons converge into a motor nerve fiber that ends on skeletal muscle. Lifting away the axon section shows how the Schwann cell wraps the myelin layers and neurolemma around the fibre.
The synaptic vesicles at the neuromuscular junction make the model particularly useful in pharmacology lab equipment sets, where lecturers explain how neuromuscular blockers and related drugs act on transmission. With the 54-feature illustrated key, it also serves well for identification exercises in physiology practicals.
Supplier
This diorama is supplied through Jain Scientific Equipments Private Limited, the Ambala, Haryana company known to its customers as ScienceLab, which provides teaching models and lab apparatus to universities, colleges and distributors. Visit the company profile for background on the company.

Frequently Asked Questions
What makes this a diorama model?
The motor neuron is reproduced in three dimensions in front of a colour backdrop that shows a network of associated neurons, so the cell is seen in context.
Does it show the neuromuscular junction?
Yes. Multiple axons converge into a motor nerve fiber that ends at the neuromuscular junction of a skeletal muscle, complete with synaptic vesicles carrying neurotransmitters.
Can the myelin sheath be examined in layers?
Yes. A section of the axon lifts off to show the layers of the myelin sheath, the neurolemma and the Schwann cell.
How are the features identified?
An illustrated key identifies 54 features on the model.
What are the size and base?
It measures 43 × 20 × 28 cm and is mounted on a hardwood base.
Can I confirm the brand and origin before ordering?
Yes. The name carries the Denoyer-Geppert brand; ask us for brand, origin and delivery details through our contact page.
