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.
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 danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
Kiesselbach was born in Shelby, Nebraska to Alexander and Caroline Bayrhoffer Kiesselbach on March 14, 1884. [1] He trained as both an undergraduate and graduate student at the University of Nebraska where he trained with Charles Bessey, receiving a BS in 1908, an MA in 1912, and a PhD in 1918. He joined the faculty of the University of ...
The plexus provides motor innervation to most muscles of the soft palate (all but the tensor veli palatini muscle) and most muscles of the pharynx (all but the stylopharyngeus muscle). [1] The larynx meanwhile receives motor innervation from the vagus nerve (CN X) via its external branch of the superior laryngeal nerve and its recurrent ...
"Dynamic Tension" is the name Charles Atlas gave to the system of physical exercises that he first popularized in the 1920s. Dynamic Tension is a self-resistance exercise method which pits muscle against muscle. The practitioner tenses the muscles of a given body part and then moves the body part against the tension as if a heavy weight were ...
The myenteric plexus (or Auerbach's plexus) provides motor innervation to both layers of the muscular layer of the gut, having both parasympathetic and sympathetic input (although present ganglion cell bodies belong to parasympathetic innervation, fibers from sympathetic innervation also reach the plexus), whereas the submucous plexus provides secretomotor innervation to the mucosa nearest the ...
