Insights

This study details the rare articular branch of the axillary artery, observed in 43.9% of dissections. Findings reveal significant gender-based differences in its occurrence, impacting shoulder joint anatomy.

Area of Science:

  • Anatomy
  • Vascular Surgery

Background:

  • The axillary artery is a critical vessel supplying the upper limb.
  • Variations in its branches can impact surgical procedures and clinical understanding.
  • The articular branch of the axillary artery is infrequently documented.

Purpose of the Study:

  • To investigate the origin, course, and variations of the articular branch of the axillary artery.
  • To analyze the prevalence and laterality of this arterial branch.
  • To determine potential gender-related differences in its anatomical presentation.

Main Methods:

  • Routine anatomical dissection of 344 axillae.
  • Recording the presence, origin, and course of the articular branch.
  • Statistical analysis to compare prevalence between sexes and sides.

Main Results:

  • The articular branch was identified in 43.9% of the dissected axillae.
  • Significant gender-based differences in prevalence were observed (P < 0.001).
  • The branch typically originated from the lateral aspect of the second part of the axillary artery.

Conclusions:

  • The articular branch of the axillary artery exhibits significant variations.
  • Understanding these variations is crucial for surgeons operating on the shoulder joint.
  • This rare observation highlights the importance of detailed anatomical knowledge in clinical practice.

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

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 Arch of Aorta01:10

The Arch of Aorta

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...

Assessing Body Temperature - Axilla

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
Veins of Upper Limbs01:17

Veins of Upper Limbs

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
