Study Notes

Hair Characteristics and Medulla Patterns

Medulla patterns can vary significantly between different species of animals and humans.
Cat hair features a thick, discontinuous medulla resembling a ladder pattern, along with a very visible spinous-scaled cuticle that resembles a palm tree.
Dog hair is characterized by a coarse texture and a continuous medulla that can be very broad at times, with a less visible cuticle compared to cat hair.
Rat hair has a narrow, clear cortex with an interrupted medulla, distinguishing it from other species.
Rabbit hair displays a compacted cortex and an interrupted medulla that forms a ball pattern, offering unique identification features.
Horse hair is notably very coarse and thick, consisting entirely of cortex with no medulla present.
Gray human hair is identified by the absence of a medulla and a clear cortex resulting from a lack of pigment.
Deer hair details were not provided but would contribute to further understanding of variations in hair characteristics.
