Little's area (Kiesselbach's plexus) receives blood supply from all of the following EXCEPT:

• A Anterior ethmoidal artery (ophthalmic artery)
• B Sphenopalatine artery (maxillary artery)
• C Greater palatine artery
• D Posterior inferior cerebellar artery (PICA) ✓

Explanation

Kiesselbach's plexus (Little's area) on the anterior nasal septum is a rich anastomotic vascular area receiving contributions from: anterior ethmoidal artery (from ophthalmic/internal carotid), sphenopalatine artery (from maxillary/external carotid), greater palatine artery (external carotid), and superior labial artery (from facial artery, external carotid). PICA is a posterior fossa artery supplying the cerebellum and has no contribution to the nasal septum vasculature.
