[Morphometric assessment of gender differences in human constitution]
Abstract:
In 154 girls and 58 young men aged 17-21 years, a new body mass index (BMI2 = M/H3), body form index (BFI=S/M2/3), body build index IBBI = (M/H3)1/2], and body fatness index (BFI = M/HC2) were determined; in which C, H, M, S correspond to the wrist circumference, body height, body mass and body area. It was shown that all the indices mentioned demonstrated highly significant gender differences if calculation of each of them was based, not on the body mass, but on a conventional body volume obtained by division of the factual body mass by the average statistical body density corresponding to 1.064 kg/dm3 in men and 1.034 kg/dm3 in women.

Introduction to the Skeletal System
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.

The Y Chromosome Determines Maleness
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....

X and Y Chromosomes
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...
