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 ...
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 .
The venous plexus of hypoglossal canal [Note 1] is a small venous plexus surrounding the hypoglossal nerve (cranial nerve XII) [1] as it passes through the hypoglossal canal. [3] [4] [5] [better source needed] The plexus connects with the occipital sinus (intercranially), inferior petrosal sinus (intercranially), internal jugular vein (extracranially), [1] condylar vein, and paravertebral ...
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.
In neuroanatomy, a plexus (from the Latin term for "braid") is a branching network of vessels or nerves. The vessels may be blood vessels (veins, capillaries) or lymphatic vessels. The nerves are typically axons outside the central nervous system. The standard plural form in English is plexuses. [1] [2] [3] Alternatively, the Latin plural ...
The exercise itself usually begins with preparation designed to relax the physical body and develop the ability to concentrate. Students may indeed be encouraged to practice Taoist Yoga exercises or tai chi as a way of building enough energy to begin performing the microcosmic orbit exercise as it can induce a strain on the nervous system and ...
