Frog Artificial Model on Board – Biology Teaching Aid
The Frog Artificial Model on Board is an educational zoological teaching model crafted to demonstrate the external morphology and internal visceral anatomy of the common bullfrog (Hoplobatrachus tigerinus / Rana tigrina). Cast from high-density, unbreakable PVC plastic and mounted securely on a finished display board, this relief model accurately replicates a ventral dissection view. It serves as an essential teaching benchmark across secondary school biology classes (SSC/HSC), university zoology departments, agricultural faculties, and veterinary training institutes throughout Bangladesh.
In modern biological education, conventional laboratory frog dissection faces severe limitations due to ethical concerns, environmental conservation policies, and the hazards of formaldehyde preservation fumes. This physical dissection model resolves these challenges by providing an anatomically realistic, permanent alternative. The ventral cutaway exposes all vital organ systems in high relief, including the multi-lobed liver, gall bladder, stomach, coiled intestines, three-chambered heart with major conus arteriosus vessels, paired lungs, kidneys, and complete male/female urogenital tracts.
The dorsal and peripheral regions highlight external morphology, limb musculature, webbed digits, and head sensory markers. Each visceral organ is sculpted and painted with non-toxic, chip-resistant pigments that clearly distinguish arterial, venous, and digestive pathways. The board comes complete with numbered identification indices paired with an attached laminated reference key, making it ideal for classroom lecture demonstrations, group self-study, and practical viva-voce exams. Victor Scientific Co. supplies precision-crafted zoological and biological models nationwide with guaranteed durability and secure packaging.
✹ Key Features
Ventral Dissection Relief Anatomy
Features an open ventral cutaway that clearly displays internal thoracic and abdominal visceral organs in realistic anatomical scale.
Comprehensive Visceral Organ Systems
Accurately shows the digestive tract, three-chambered heart with aortic arches, respiratory lungs, renal excretory system, and urogenital organs.
Ethical & Reusable Teaching Alternative
Eliminates the need for sacrificing live amphibians and removes toxic chemical preservatives (formalin) from school laboratories.
Durable, Impact-Resistant Build
Fabricated from medical-grade PVC plastic mounted on a finished wooden or heavy-duty polymer baseboard that resists cracking, chipping, and tropical humidity.
Vibrant Multi-Color Painted Finish
Uses fade-resistant, non-toxic colors that clearly separate arteries (red), veins (blue), liver/gallbladder (brown/green), and intestinal structures.
Numbered Demonstration Key Card
Features clear numerical indices stamped beside each internal structure corresponding to an included laminated identification legend for spot tests.
Wall-Mountable and Benchtop-Ready
Designed with a balanced footprint suitable for demonstration easels or secure wall hanging in school science and zoology laboratories.
