Front

What is the medulla pattern that is characterized by a continuous appearance?

Back

Continuous medulla pattern is a type of hair medulla that appears unbroken and continuous throughout the length of the hair.

Front

In the pencil analogy, which part of the hair corresponds to the lead?

Back

The medulla corresponds to the lead in the pencil analogy, as it is the central core of the hair.

Front

What scale pattern is used to identify human hair?

Back

Imbricate scale pattern is used to identify human hair, characterized by flattened and overlapping scales.

Front

What protein is the hair shaft primarily composed of?

Back

The hair shaft is primarily composed of keratin, a fibrous protein that provides strength and structure.

Front

Which structure of the hair is most important for individualization?

Back

The follicle is the most important structure for the individualization of hair, as it contains DNA and other identifying features.

Front

What are the three main parts of a hair strand?

Back

The three main parts of a hair strand are the cuticle, cortex, and medulla.

Front

What is the function of the cuticle in hair?

Back

The cuticle serves as the outer protective layer of the hair, helping to prevent damage and moisture loss.

Front

How does the cortex contribute to hair properties?

Back

The cortex contains the majority of the hair's pigment and is responsible for the hair's strength, elasticity, and texture.

Front

What is the significance of the hair follicle in forensic analysis?

Back

The hair follicle is significant in forensic analysis because it can provide DNA evidence, which is crucial for individual identification.

Front

What are the differences between fragmented, continuous, and interrupted medulla patterns?

Back

Fragmented medulla has breaks, continuous medulla is unbroken, and interrupted medulla has regular gaps.
