Chapter 11, Problem 5ACT

(a)

Summary Introduction

To determine: The medulla pattern present in the given hair sample.

Introduction: In most of the crime scene the sample of the hair is encountered as physical evidence. The different forms of hair are present depending on their morphology and structure.

(b)

Summary Introduction

To determine: The medulla pattern present in the given hair sample.

Introduction: The primary step in identifying the hair is to study the color and more information about the extraction of DNA and its different characters.

(c)

Summary Introduction

To determine: The medulla pattern present in the given hair sample.

Introduction: The collection of cells that can be observed running in the central canal is termed as the medulla. This canal is regarded as the predominant feature that covers half of the diameter of the hair.

(d)

Summary Introduction

To determine: The medulla pattern present in the given hair sample.

Introduction: The growth of the hair is dependent on the root and the type of cells surrounding it. The three phases are present in the growth which is termed as anagen, catagen, and telogen.

(e)

Summary Introduction

To determine: The medulla pattern present in the given hair sample.

Introduction: The hair comprises of the filamentous cells that are made up of keratins. A single strand of hair can be enough in identifying the culprit. Coronal, spinous and imbricate are the different types of scale patterns found in the hairs.

(f)

Summary Introduction

To determine: The medulla pattern present in the given hair sample.

Introduction: The primary purpose to examine the hair strand is to recognize the type of hair that belongs to an animal or a human.

(g)

Summary Introduction

To determine: The medulla pattern present in the given hair sample.

Introduction: The shape of the hair can be determined by the type of medulla present in them. The medulla present in the humans gives the shape to the hairs as a cylindrical in appearance.

(h)

Summary Introduction

To determine: The identification of the type of hair based on the medulla pattern.

Introduction: The comparisons of the hairs are done based on different features. These characteristics include the matching of the color, the diameter, and the length of the hair.

(i)

Summary Introduction

To determine: The hair sample present in the given picture does not contain a medulla.

Introduction: The cortex of the hair is present in the cuticle that serves as a protective layer for the hairs. The cortex can be considered in the case of investigation because the cells that give a specific color to the hairs are present in here.
