Summary
This case report details rare variations in the axillary artery (AA) branching and associated nerve patterns in a Greek male cadaver. Understanding these anatomical anomalies is crucial for surgical safety in the shoulder region.
Area of Science:
- Anatomy
- Vascular Anatomy
- Neuroanatomy
Background:
- The axillary artery (AA) is a major artery in the upper limb, originating from the subclavian artery.
- Variations in its branching pattern can impact surgical procedures and diagnosis.
Observation:
- A unilateral branching pattern of the right axillary artery (AA) was observed in a Greek male cadaver.
- This included an unusual common trunk division, vessel multiplications, and accessory lateral thoracic arteries.
Findings:
- A high-level interconnection between the musculocutaneous and median nerves, forming an accessory lateral root of the median nerve, was identified.
- A rare innervation of the upper latissimus dorsi muscle by the lower subscapular nerve was also noted.
Implications:
- Detailed knowledge of axillary artery (AA) branching variations and concomitant neural anomalies is vital for surgeons.
- Awareness of these variations aids in safer diagnoses and uneventful surgical procedures in the axillary region.

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.

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.

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

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 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...
