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."

Oh, I cannot tell you to make up your mind
And gather together the best of your kind
The prophets have spoken the words of ill fate
YOur childhood has ended you've taken the bait
YOu've got the power it's there deep inside
Just look around and you'll know what you've tried
So much relies on the course that you take
The fool and the wise man both burn at the stake-ah
Look at the heads buried deep in the sand
Hiding from evil made by their own hand
The prophets have spoken the words of ill fate
Your childhood has eneded you've taken the bait
You've got the power it's there deep iniside
JUst look around and you'll know what you've tried
So much relies on the course that you take
The fool and the wise man both burn at the stake-ah
