A plexus (from the Latin 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.
Although many medical words ending in -us that came to English from Latin have the plural suffix -i (and the plural form plexi indeed does exist in Latin), English does not use the -us/-i pattern for this particular term; the standard plural form in English is plexuses.
The plexus is the characteristic form of nervous system in the coelenterates and persists with modifications in the flatworms. The nerves of the radially symmetric echinoderms also take this form, where a plexus underlies the ectoderm of these animals and deeper in the body other nerve cells form plexuses of limited extent.
The Rosy Crucifixion, a trilogy consisting of Sexus, Plexus, and Nexus, is a fictionalized account documenting the six-year period of Henry Miller's life in Brooklyn as he falls for his second wife June and struggles to become a writer, leading up to his initial departure for Paris in 1928.
Sexus (1949), the first volume, describes the break-up of Miller’s first marriage to Maude as he meets, falls in love with and marries his second wife, the captivating and mysterious dancer Mona (June). All the while, he feels guilty for leaving Maude, and becomes more attracted to her following their divorce. At the beginning of Sexus, Miller is 33 years old. June is at first called Mara, but at the beginning of chapter 8, and for the remainder of the trilogy, her name is changed to Mona. Miller states that this is under the influence of his friend Dr. Kronski, and that the name change accompanied "other, more significant changes." She is one who has changed many details of her life: "her name, her birthplace, her mother, her upbringing, her friends, her tastes, even her desires."

Morumbi (Brazilian Portuguese: [moɾũˈbi]) is a district of the city of São Paulo belonging to the subprefecture of Butantã, in the southwestern part of the city. A common folk etymology attributes its name to the mixed Portuguese and Tupi phrase morro obi, which would mean "green hill", but this is disputed.
Morumbi is between 9 and 15 km away from São Paulo's downtown. It has boundaries with the districts of Vila Sônia, Campo Limpo, Vila Andrade, Itaim Bibi, Pinheiros, and Butantã. Within Morumbi, the neighborhoods of Vila Progredior, Caxingüi, Jardim Guedala, Cidade Jardim, Real Parque, Vila Morumbi, Paineiras do Morumbi, Jardim Panorama, Jardim Sílvia, Vila Tramontano and Paraisópolis are found.
Ranked first by many years in real estate launches, it was always considered by the citizens of São Paulo as sophisticated and as one of the wealthiest neighborhoods of the city, despite the existence of the Paraisópolis favela.
Within the boundaries of Morumbi one may find Hospital Israelita Albert Einstein, one of the most important private hospitals of the city, Palácio dos Bandeirantes, seat of the São Paulo state government, the American School (Graded School), the Colégio Visconde de Porto Seguro Unidade 1 and Estádio do Morumbi, home to São Paulo Futebol Clube.
