Summary
A rare cleidocervical muscle was identified, originating from the 6th cervical vertebra and inserting onto the clavicle. This anatomical variant, innervated by the 5th cervical nerve, likely stems from the longus colli muscle.
Area of Science:
- Anatomy
- Morphology
- Human Anatomy
Background:
- Anatomical variations are crucial for understanding human musculoskeletal system.
- The cervical vertebrae and clavicle form key structures in the neck and shoulder girdle.
Observation:
- A distinct cleidocervical muscle was observed.
- This muscle originated from the anterior tubercle of the transverse process of the 6th cervical vertebra.
- Its insertion point was identified on the superior margin of the clavicle.
Findings:
- The cleidocervical muscle received innervation from the 5th cervical nerve.
- Topographic anatomical analysis suggests an origin from the longus colli muscle.
- This represents a rare anatomical variant in human skeletal musculature.
Implications:
- Understanding such anatomical variations is vital for surgical procedures in the neck and shoulder region.
- This finding contributes to the detailed knowledge of human cervical and pectoral musculature.
- Further research may explore the functional significance and prevalence of this muscle variant.
