About this mock
UGC-NET Forensic Science Unit VII drill on hair structure and morphology fundamentals for forensic identification. Covers the three-layer gross anatomy of hair (cuticle, cortex, medulla), growth cycle phases (anagen, catagen, telogen) and their forensic significance, cuticle scale patterns (imbricate, coronal, spinous) for human versus animal differentiation, pigment biology (eumelanin, pheomelanin, melanin granule distribution), and the medullary index as the primary numerical marker distinguishing human hair (less than 0.33) from animal hair (greater than 0.5). Root morphology at the anagen and telogen stages is examined alongside the light microscopy magnification range (10x to 400x) used at CFSL Hyderabad, CFSL Chandigarh, and DFSS laboratories across India.
The Indian forensic context addresses hair examination practice at the Central Forensic Science Laboratory network, the role of ASTM E2227 (Standard Guide for Forensic Examination of Non-Reactive Dyes in Textile Fibers and Hair) and SWGMAT (Scientific Working Group for Materials Analysis) guidelines for trace-evidence hair comparison, chain-of-custody requirements under the Bharatiya Nagarik Suraksha Sanhita (BNSS) 2023, and the regional significance of CDFD Hyderabad for DNA-linked hair evidence. Questioned versus reference sample collection protocols and packaging SOPs for hair trace evidence are tested at the definitional level suited to first-pass UGC-NET Paper II preparation.
Topics covered:
- Cuticle, cortex, and medulla: structure and forensic role
- Anagen, catagen, and telogen growth phases
- Scale patterns: imbricate, coronal, and spinous
- Eumelanin vs pheomelanin and melanin granule distribution
- Medullary index: human less than 0.33, animal greater than 0.5
- Head, pubic, and body hair distinguishing features
- Root morphology: anagen sheath vs telogen club
- Hair collection, packaging, and ASTM E2227/SWGMAT SOPs
Calibrated for first-pass UGC-NET Forensic Science Paper II preparation and NFSU MSc Forensic Chemistry entrance revision. Allow 30 minutes.
