A Microscopic Study of the Hair of the Rabbit, with Special Reference to its Form of Cross-section and Granular Pigmentation

This study microscopically examined rabbit hairs, focusing on cross-sectional forms and granular pigmentation across six hair color classifications: Black, Havana Rex, Golden, Chinchilla, Wild, and White. Key findings include the bamboo-like structure of the cortical and medullary regions, a dumb-bell shape near the tip of guard hairs, and the distribution of pigment granules, which are more abundant in the parenchymatous septa than in the cortex. Hair color is influenced by the tint and distribution of these granules. Notably, Chinchilla and Wild hairs have a light-colored middle section, with Chinchilla having fewer black granules in this area compared to Wild.
