Nervous System
The central nervous system of harvestmen, which evolved from a segmented structure, is centralized around the esophagus. The part above the esophagus (syncerebrum) consists of protocerebrum (associated with the eyes) and deutocerebrum (associated with the chelicerae). The nerves of the pedipalp, walking legs, and some for the opisthosoma emerge from the part below the esophagus. The peripheral nervous system is not well studied.

Famous quotes containing the words nervous and/or system:
“When General Motors has to go to the bathroom ten times a day, the whole country’s ready to let go. You heard of that market crash in ‘29? I predicted that.... I was nursing a director of General Motors. Kidney ailment, they said; nerves, I said. Then I asked myself, “What’s General Motors got to be nervous about?” “Overproduction,” I says. “Collapse.””
—John Michael Hayes (b. 1919)
“Nobody is glad in the gladness of another, and our system is one of war, of an injurious superiority. Every child of the Saxon race is educated to wish to be first. It is our system; and a man comes to measure his greatness by the regrets, envies, and hatreds of his competitors.”
—Ralph Waldo Emerson (1803–1882)
