Key Structures

Topics include the cervical plexus and its sensory and motor branches, as well as additional nerves relevant to cervical function and clinical examination.

Clinical Relevance and Learning Focus

Knowledge of cervical nerve pathways supports diagnosis of neuropathies, interpretation of referred pain and safe application of regional anaesthesia.
