Description

This educational demonstration tool provides a detailed look into the bone structure of two distinct vertebrate classes: birds (Aves) and mammals (Mammalia).

Features longitudinal and cross sections of real femur bones of a chicken and a dog, offering a side-by-side comparison of the femur bones of a bird and a mammal, highlighting key differences in their skeletal structures. The chicken femur sections reveal the characteristic light, hollow bones of birds, designed to reduce weight and facilitate flight. Despite being hollow, the bone maintains strength through a delicate internal trabecular network, which provides structural support without compromising on flexibility.

This is a key adaptation for birds, even ground-dwelling species like chickens.

In contrast, the dog femur sections showcase the solid, dense bone structure typical of mammals. The thick cortical bone provides strength and durability, supporting the dog's higher body weight and the stresses of movement. The compact nature of the bone reflects the evolutionary adaptations mammals have made for terrestrial locomotion.

The bones are mounted on a solid, elegant wooden base plate for easy observation. Each specimen is carefully prepared to reveal the internal architecture, making it an excellent resource for comparative anatomy studies. It offers students and educators a clear visual aid for understanding the relationship between skeletal form and function.

The product includes an acrylic showcase too, to ensure durability while allowing for clear viewing, making it perfect for classrooms, labs or museums.
