Spigelian hernia the morbidity and cost associated with foreign material. Adriaan van den Spiegel, a surgeon-anatomist born in Brussels, described this hernia. The first publication was in 1645, twenty years after Spiegel's death. Dr. Raveenthiran of SRM Hospital, Kattankulathur described a new syndrome in which Spigelian hernia and cryptorchidism (undescended testis) occur together. Spigelian hernia A Spigelian hernia (or lateral ventral hernia) is a hernia through the Spigelian fascia, which is the aponeurotic layer between the rectus abdominis muscle medially, and the semilunar line laterally. These are generally interparietal hernias, meaning that they do not lie below the subcutaneous fat but penetrate
Composition of the human body are averages of different numbers reported by different references. The adult human body averages ~53% water. This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. Water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent, and these numbers along with the complementary % numbers for oxygen in water, are the largest contributors to overall mass and atomic composition figures. Because of water content, the human body
