Summary
This summary is machine-generated.This study reports a rare combination of anatomical variations in the forearm, including a bitendinous palmaris longus muscle and a double-headed accessory abductor digiti minimi. These findings highlight the importance of understanding anatomical variations for clinical practice.
Area Of Science
- Anatomy
- Human Morphology
- Clinical Anatomy
Background
- The palmaris longus (PL) muscle exhibits significant morphological variability and agenesis.
- Variations in the abductor digiti minimi and superficial ulnar artery are known but rarely coexist.
Purpose Of The Study
- To document and describe an exceptionally rare triad of anatomical variations in the human forearm and hand.
- To emphasize the clinical significance of recognizing such anatomical anomalies.
Main Methods
- Routine anatomical dissection of an adult male cadaver.
- Detailed observation and documentation of variations in the palmaris longus, abductor digiti minimi, and ulnar artery.
- Comparison with the contralateral limb.
Main Results
- A bitendinous palmaris longus with a central muscle belly was identified.
- A double-headed accessory abductor digiti minimi was observed, with its lateral head originating from the PL tendon.
- A superficial ulnar artery coursing over the PL tendon was noted.
- The contralateral side showed a bifid PL tendon without other associated variations.
Conclusions
- The coexistence of these specific anatomical variations is exceptionally rare.
- Awareness of such anomalies is crucial for accurate diagnosis and effective surgical intervention.
- Detailed anatomical knowledge aids in preventing iatrogenic complications.

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...
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...
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.
The radius has a nail-shaped head, and a...
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
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...
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 Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...
