Summary
This summary is machine-generated.The persistent median artery, a remnant of embryonic circulation, is surprisingly common in adults at 43%. Its presence did not significantly alter the diameters of the main radial or ulnar arteries.
Area Of Science
- Anatomy
- Embryology
- Vascular Biology
Background
- The median artery is an embryonic artery that typically regresses during development.
- Persistence of the median artery in adults is a known anatomical variation.
Purpose Of The Study
- To determine the prevalence of the persistent median artery in the adult population.
- To investigate the vascular consequences associated with its presence.
Main Methods
- Dissections of 56 adult upper extremities (112 total).
- Recording prevalence of antebrachial and palmar types of persistent median artery.
- Measuring and statistically analyzing radial and ulnar artery diameters with and without the persistent median artery.
Main Results
- A persistent median artery was found in 43% of the studied upper limbs.
- Antebrachial and palmar types occurred in 28% and 15% of cases, respectively.
- No significant differences in mean radial or ulnar artery diameters were observed with or without the persistent median artery.
Conclusions
- The persistent median artery is highly prevalent in the adult population.
- Understanding its anatomy is crucial for surgeons, particularly those operating in the carpal tunnel or distal forearm.
- Further research may explore clinical implications beyond arterial diameter.

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
