A nosebleed (epistaxis) usually occurs in the anterior part of the nose from an area known as Kiesselbach's plexus which consists of arteries. Woodruff's plexus is a venous plexus in the posterior part and a nosebleed here accounts for only between 5 and 10 per cent of nosebleeds. Older adults are most often affected. [5]
Kiesselbach's plexus is an anastomotic arterial network (plexus) of four or five arteries in the nose supplying the nasal septum. It lies in the anterior inferior part of the septum known as Little's area, Kiesselbach's area, or Kiesselbach's triangle. It is a common site for anterior nosebleeds.
Most nosebleeds occur in Kiesselbach's plexus, a vascular plexus in the lower front part of the septum involving the convergence of four arteries. A smaller proportion of nosebleeds that tend to be nontraumatic occur in Woodruff's plexus. Woodruff's plexus is a venous plexus of large thin-walled veins lying in the posterior part of the inferior ...
This area is richly endowed with blood vessels (Kiesselbach's plexus). This region is also known as Little's area . Bleeding farther back in the nose is known as a posterior bleed and is usually due to bleeding from Woodruff's plexus , a venous plexus situated in the posterior part of inferior meatus. [ 17 ]
Wilhelm Kiesselbach (1 December 1839 – 4 August 1902) was a German otolaryngologist born in Hanau. From 1859 he studied medicine at the universities of Göttingen , Marburg and Tübingen . In 1877/78 he worked as assistant under Wilhelm Olivier Leube in the polyclinic at the University of Erlangen .
Woodruff's long career in journalism has included time at CNN and NBC News. She was host of PBS' “NewsHour” between 2013 and 2022, before stepping down for a reporting project.
The deep branches pass beneath the zygomaticus and the quadratus labii superioris, supplying them and forming an infraorbital plexus with the infraorbital branch of the maxillary nerve. These branches also supply the small muscles of the nose.
The anterior pulmonary plexus is close in proximity to the pulmonary artery. [1] The posterior pulmonary plexus is bounded by the superior edge of the pulmonary artery and the lower edge of the pulmonary vein. [1] Both lungs are innervated primarily by the posterior pulmonary plexus; it accounts for 74–77% of the total innervation. [1]
