Summary
Complex anatomical variations of the brachial artery and nerves in the humeral region were discovered during dissection. These findings highlight the importance of understanding nerve and artery variations for clinical practice.
Area of Science:
- Anatomy
- Human Anatomy
- Surgical Anatomy
Background:
- Anatomical variations in the upper limb can impact surgical procedures and diagnosis.
- The brachial plexus and its branches, including the musculocutaneous nerve, exhibit frequent variations.
- Superficial positioning of the brachial artery is an uncommon but documented anomaly.
Purpose of the Study:
- To document and analyze a rare complex of anatomical variations in the humeral region.
- To discuss the potential clinical and surgical implications of these variations.
- To explore the embryological basis for the observed anomalies.
Main Methods:
- Cadaveric dissection of the humeral region.
- Detailed morphological analysis of vascular and neural structures.
- Comparative review of existing anatomical literature.
Main Results:
- Right Upper Limb: Superficial course of the brachial artery.
- Right Upper Limb: Musculocutaneous nerve bypassed the coracobrachialis muscle inferiorly.
- Left Upper Limb: Communication identified between the musculocutaneous and median nerves.
Conclusions:
- The reported variations, including superficial brachial artery and aberrant nerve pathways, underscore the need for heightened awareness in clinical settings.
- Understanding these anatomical anomalies is crucial for preventing iatrogenic injuries during upper limb surgeries.
- Embryological factors likely contribute to the development of these complex variations, necessitating further investigation.

01:12Arteries of the Upper Limbs
3.2K
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...

01:09Bones of the Upper Limb: Radius
11.6K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

01:19Bones of the Upper Limb: Humerus
14.6K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:12Regional Terms
16.8K
Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

01:15Bones of the Upper Limb: Ulna
11.2K
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...

01:22Spinal Nerves: Plexus I
3.6K
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.
