The median artery has been considered as an embryonic structure, which normally regresses around the 8th week of gestation. However, various prevalences have been reported in adults since the 18th century. Furthermore, in a study by Henneberg and George (1995; Am J Phys Anthropol 96, 329–334), has suggested that increasing prevalence of the median artery during the 20th century was a ‘possible secular trend’. The present study, conducted nearly a quarter of a century later, is a continuation of… 

Accessory heads of the biceps brachii muscle: A systematic review and meta‐analysis

The overall prevalence of the accessory heads and related questions, such as their broad morphological features, population variance, sexual dimorphism, side distribution or the changes in prevalence rates over time are investigated.

The prevalence of the azygos lobe: A meta‐analysis of 1,033,083 subjects

A evidence‐based synthesis of AL prevalence is presented, demonstrating publication bias and small‐study effects in the anatomy literature, and its relationships with other variables such as population, diagnostic methods, and co‐occurring illnesses.

The persistent median artery: A new challenger in carpal tunnel imaging?

PMA accompanied by median nerve variations is frequently seen and should be cautiously evaluated using imagery, particularly in young patients before wrist surgery.

Anatomical variations of the superficial palmar arch in human fetuses

Knowledge of the superficial palmar arch variations will contribute to hand microsurgery particularly in vascular graft and free flap application interventions for arterial bleeding in the palmar region.

Sacral Spina Bifida Occulta: A Frequency Analysis of Secular Change

Substantial relaxation of natural selection beginning around 1900 changed the mutation/selec­tion balance of modern genetic material, producing an increase in variable anatomical structures. While

Persistent median artery may explain the transition from 11 to 12 meridians in ancient Chinese medicine

The 12th meridian, Hand Jue Yin Meridian, happens to run along the same pathway as PMA, which may explain well the mystery why a "new meridian" was added to the older 11-meridian system over two thousand years ago in Chinese medicine.

Anatomy of the nerves, vessels, and muscular compartments of the forearm, as revealed by high-resolution ultrasound. Part 2: vascularization of compartments and cutaneous innervation

The aim of these two companion articles is to present the normal anatomy of the nerves and compartments of the forearm, as revealed by HRUS, as well as the relationships between the main vessels and nerves of the region.

Three hand yin meridians in ancient Chinese medicine were established initially based on arterial structures

I agree with the first concept proposed by Kumaratilake et al. (2020) that vertical blood vessels represent meridians, and descriptions from the silk meridian books unearthed from Mawangdui Han Tomb are supported.

The species of homo

At the point of this writing, species of homo is, in modern science, limited to past and current inhabitants of planet Earth. However, my earlier work shows that planets are also living beings and

A further morphological study of the persistent median artery in neonatal cadavers

The possibility that the median artery regresses at a later age, possibly during perinatal and early infancy period, is raised and this may be due to evolutionary and racial trends.

Median artery revisited

It is confirmed that the median artery may persist in adult life in 2 different patterns, palmar and antebrachial, based on their vascular territory, which are large, long and reaches the palm.

High incidence of the median artery of the forearm in a sample of recent southern African cadavers.

A different approach to description of normal human anatomy is therefore necessary--that of presenting alternative anatomical patterns of equal standing rather than a single 'normal' pattern.

A preliminary survey of the median artery in human cadavers of South Indian origin.

Investigation of the incidence and course of the palmar type of the median artery in South Indian cadavers found that it is possible that the artery may compress the anterior interosseous nerve and cause the anterior Interosseus nerve syndrome.

Median artery of the forearm in human fetuses in northeastern Brazil: anatomical study and review of the literature

The objective of this study was to research the frequency, type (forearm or palmar) and origin of the median artery in fetuses, correlating its presence with sex and body side and to be aware of this anatomical variation.

An anatomical study and ontogenetic explanation of 23 cases with variations in the main pattern of the human brachio-antebrachial arteries.

Either the total or partial persistence of the superficial arterial segments explains those cases of high origin of either the radial or ulnar arteries as well as the duplications of the brachial artery.

Incidence of the persistent median artery of the forearm in Myanmar adults

This study confirms that persistence of the median artery is not uncommon and is statistically frequent among male individuals, occurring bilaterally more often than unilaterally.

A further study of the high incidence of the median artery of the forearm in Southern Africa.

These findings are much higher than those of earlier studies and may be explained by differences in the thoroughness of the observations or regional variation, or by the occurrence of a secular trend in the development of vasculature.

The median artery of the forearm provides an additional route of blood supply to the forearm that should be kept in mind by hand surgeons and it can also be harvested for vascular grafts.

Prevalence of the persistent median artery: an ultrasound study

The findings obtained from this study demonstrate a prevalence rate in line with similar studies reported in published literature, and indicates that surgeons operating in the wrist region should be aware of the possibility of the presence of the persistent median artery to prevent iatrogenic injury.
