Area of Science:

Anatomy
Human Anatomy
Skeletal Muscle Anatomy

Background:

Anatomical variations are crucial for understanding human musculoskeletal system diversity.
The M. cervico-humeralis is a rare accessory muscle with limited documented cases.
Variations in muscle anatomy can impact surgical procedures and biomechanical studies.

Observation:

A bilateral M. cervico-humeralis was identified in a 50-year-old Japanese male during dissection.
The muscle presented consistently on both sides, originating from cervical vertebrae (VC6, VC7) transverse processes.
It coursed with the brachial plexus and subclavian vessels to insert on the humerus' medial surface.

Findings:

The bilateral M. cervico-humeralis exhibited similar morphology, origin, course, and insertion.
The muscle's tendon passed through the brachial plexus before inserting on the humerus.
Nerve supply originated from the posterior cord of the brachial plexus, and arterial supply from the axillary artery.

Implications:

This case represents the first reported bilateral occurrence of the M. cervico-humeralis in Japan.
Understanding such anatomical variations is vital for accurate diagnosis and surgical planning in the shoulder and neck regions.
The detailed description contributes to the existing knowledge base of human anatomical anomalies.
