Correct Answer � A
Explanation
|
|
Kiesselbach’s plexus, which lies in Kiesselbach’s area, Kiesselbach’s triangle, or Little’s area, is a region in the anteroinferior part of the nasal septum where four arteries anastomose to form a vascular plexus.
The arteries are:
- Anterior and posterior ethmoidal artery (branch of the ophthalmic artery, ICA)
- Sphenopalatine artery (terminal branch of the maxillary artery)
- Greater palatine artery (from the maxillary artery)
- Septal branch of the superior labial artery (from the facial artery)
