Which of the following blood vessels does not take pa in anastomosis in the area encircled in red of the nasal septum?
Little's area or Kiesselbach's plexus:This is the vascular area in the anteroinferior pa of nasal septum just above the vestibule. Anterior ethmoidal, sphenopalatine, greater palatine and septal branch of superior labial aeries and their corresponding veins form an anastomosis here. This is the commonest site for epistaxis. This is also the site for the origin of the "bleeding polypus" (haemangioma) of the nasal septum.Ref: Dhingra; 6th ed; Pg: 147
