Cephalometry is the scientific measurement of the dimensions of head. The name Cephalometry is grain to the morphological study of all structures present in the human head. Cephalometry is a branch of Anthropometry.
Anthropometry may perhaps be most simply and comprehensively defined as the conventional art or system of measuring the human body and its parts. The systems of measuring the skull and the skeleton are known separately as craniometry and osteometry, but these terms are frequently merged with that of anthropometry ;thus we speak only of anthropometric instruments, anthropometric methods in anthropometric laboratories.

Research Objectives and Core Themes
This study aims to examine sexual and racial variations in cephalic indices among North Indian students at Teerthanker Mahaveer University. By utilizing cephalometric measurements, the research investigates the morphometric characteristics of the human head to provide data useful for anthropological, forensic, and clinical identification purposes.
- Cephalometric measurement of North Indian student populations.
- Evaluation of sexual dimorphism in cephalic indices.
- Comparative analysis of head shapes (brachycephalic, mesocephalic, dolichocephalic).
- Application of cephalic index in forensic and medico-legal identification.
- Correlation of current findings with established secular trends in craniometry.
Excerpt from the Book
HISTORICAL REVIEW
Cephalic index was first identified by Swedish Professor of Anatomy Anders Rezitus (1796-1860). With the passage of time constant changes occurred in the structural appearances of human life as evolution. Evolution is defined as genetic change overtime. CHARLES DARWIN defined evolution as “Descend with modification”. Anthropology is a science founded on evolutionary principles. Cephalic index is the term used in anthropology to find out racial differences, sexual differences which are of great significance in diagnosing medico legal cases of forensic medicine.
Man is fond of making comparison to prove his superiority over the increasing size of Phylogeny. Measurements serve as an important guideline for Comparison. Comparative changes in the cephalic index between parents, offspring, and siblings towards their genetic transmission of inherited characteristics.

Frequently Asked Questions
What is the core focus of this research?
The research focuses on the scientific measurement of head dimensions (cephalometry) to determine the cephalic index and head shape variations among North Indian students.
Which population was studied?
The study examines 800 students (400 males and 400 females) of cosmopolitan origin at Teerthanker Mahaveer University, aged 17–25 years.
What is the primary objective of this project?
The primary objective is to evaluate sexual and racial variations in cephalic indices and to demonstrate their significance for forensic and anthropological identification.
What methodology was employed to collect data?
The study used Hrdlicka’s method, utilizing spreading calipers to measure the maximum head length and maximum head breadth under relaxed conditions.
What does the main body of the work cover?
It covers historical contexts, a comprehensive literature review of global cephalometric studies, detailed statistical observations, and a critical discussion of results compared to prior research.
Which keywords define this study?
Key terms include Cephalic Index, Anthropometry, Craniometry, Brachycephalic, and Forensic Medicine.
What specific role does the cephalic index play in forensic medicine?
It acts as a diagnostic tool to help identify the race and sex of individuals in medico-legal cases, especially when only cranial remains are available.
What was the key finding regarding the head shape of the studied population?
The majority of the students, both male and female, were found to be brachycephalic, suggesting a trend towards brachycephalisation in the studied population.
How did the study confirm the statistical significance of its findings?
The researcher applied a Z test for large samples (n=800) to compare the means of head length, breadth, and cephalic index between genders.
Why is "brachycephalisation" considered an important observation here?
The author notes that this trend serves as an evidence of continuous brain growth in the lateral direction, which is considered a relevant parameter for human evolution.
