Summary
Multiple arterial variations in a single upper limb were observed, including superficial brachial artery continuation as the radial artery and deep brachial artery as the ulnar artery. The median artery originated from the ulnar artery, forming princeps pollicis and radialis indicis arteries.
Area of Science:
- Anatomy
- Human Anatomy
- Vascular Anatomy
Background:
- Variations in upper limb arterial patterns are common during anatomical dissections.
- However, encountering multiple arterial variations within a single limb is rare.
Purpose of the Study:
- To document and describe a unique case of multiple arterial variations in a single human upper limb.
- To highlight the anatomical significance of these variations for clinical and surgical practice.
Main Methods:
- Dissection of a left amputated upper limb from a female cadaver.
- Detailed observation and documentation of arterial and nerve variations below the intercondyler line.
Main Results:
- The superficial brachial artery continued as the radial artery.
- The deep brachial artery persisted as the ulnar artery, originating the median artery.
- The median artery supplied the princeps pollicis and radialis indicis arteries.
- The median nerve looped around the median artery before bifurcating.
Conclusions:
- This case presents a rare confluence of multiple arterial variations in one upper limb.
- Understanding such variations is crucial for surgeons and clinicians to avoid complications during procedures involving the upper limb vasculature and nerves.

01:12Arteries 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...
01:22Spinal Nerves: Plexus I
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.

01:17Veins 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...

01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
