What is the cuticle in hair structure?

Back

The cuticle is the outermost layer of the hair shaft, resembling the paint on a pencil, providing protection to the inner layers.

Front

What does a fragmented medulla indicate?

Back

A fragmented medulla is characterized by breaks or gaps in the medulla pattern, which can help in identifying the species of origin.

Front

What is a continuous medulla?

Back

A continuous medulla is a solid, uninterrupted line of cells running through the center of the hair, often seen in certain animal hairs.

Front

What does it mean if a hair has no medulla?

Back

If a hair has no medulla, it means that the central core is absent, which can be a distinguishing feature in forensic analysis.

Front

What is the cortex in hair structure?

Back

The cortex is the middle layer of the hair shaft, containing the majority of the hair's pigment and providing strength.

Front

How can the medulla pattern assist in forensic analysis?

Back

The medulla pattern can help forensic scientists determine the species of the hair and potentially link it to a suspect.

Front

What are the three main types of medulla patterns?

Back

The three main types of medulla patterns are continuous, fragmented, and interrupted.

Front

Why is the cuticle important in hair analysis?

Back

The cuticle's structure can provide information about the hair's origin and condition, aiding in forensic identification.

Front

What role does the cortex play in hair color?

Back

The cortex contains melanin, which gives hair its color; variations in melanin levels result in different hair colors.

Front

What is the significance of hair in forensic science?

Back

Hair can provide valuable evidence in criminal investigations, helping to link suspects to crime scenes.
