Cervicoaxillary canal

Cervicoaxillary Canal is a passage that allows neurovascular structures to pass from the neck to the axilla. It is bordered by the clavicle anteriorly, the first rib inferiorly, and the scapula posteriorly.

Anatomy

The Cervicoaxillary Canal is a pathway that allows the passage of the brachial plexus and the subclavian artery from the neck to the axilla. It is formed by the clavicle anteriorly, the first rib inferiorly, and the scapula posteriorly.

Function

The primary function of the Cervicoaxillary Canal is to provide a conduit for the brachial plexus and the subclavian artery to pass from the neck to the axilla. This is crucial for the innervation and vascular supply of the upper limb.

Clinical Significance

Injury to the structures passing through the Cervicoaxillary Canal can result in significant morbidity. For example, trauma to the brachial plexus can result in loss of function of the upper limb. Similarly, injury to the subclavian artery can result in significant bleeding and potentially life-threatening hemorrhage.
