Morphometric Assessment Methods for Estimation of Sexual Dimorphism from Cranial Occipital Condyles

Human Adult Occipital Condyles : A Morphometric Analysis

This study proposed to morphologically analyze the adult human occipital condyle, estimate the bilateral differences, sexual dimorphism and compare with the available data. We conducted this study on hundred occipital condyles in fifty dry human skulls. The measurement was performed by the means of the vernier’s caliper on both sides of the skull. The parameters measured are length, width, heig...

Magnetic Resonance Imaging-Based Morphometric Assessment of Sexual Dimorphism of Corpus Callosum

Introduction: Interhemispheric transmission of signal is done by corpus callosum (CC) as the largest fiber tract in brain. CC comprised 5 segments of rostrum, genu, body, isthmus, and splenium. Contradictory reports exist about sexual dimorphism of CC. We designed this study to assess probable sexual differences of CC and its different parts in men and women. Methods: We analyzed magnetic reso...

Sexual Dimorphism Using Geometric Morphometric Approach

Geometric Morphometric Sex Estimation for Hatchling Turtles: A Powerful Alternative for Detecting Subtle Sexual Shape Dimorphism

Identifying sex of hatchling turtles is difficult because juveniles are not obviously externally dimorphic, and current techniques to identify sex are often logistically unfeasible for field studies. We demonstrate a widely applicable and inexpensive alternative to detect subtle but significant sexual dimorphism in hatchlings, using landmark-based geometric morphometric methods. With this appro...

Surgical anatomy and morphometric analysis of the occipital condyles and foramen magnum.

Surgical anatomy that provides the basis for dealing with lesions arising in the lower clivus and ventral foramen magnum was reviewed in 8 adult cadaver heads and 76 dry skulls. The extreme lateral transcondylar approach was performed in cadavers; the morphometric analysis was studied in both the cadavers and the skulls. The landmarks, distances and structures were selected in order to guide th...
