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 related to nervous system:
“A car can massage organs which no masseur can reach. It is the one remedy for the disorders of the great sympathetic nervous system.”
—Jean Cocteau (1889–1963)
“A two-week-old infant cries an average of one and a half hours every day. This increases to approximately three hours per day when the child is about six weeks old. By the time children are twelve weeks old, their daily crying has decreased dramatically and averages less than one hour. This same basic pattern of crying is present among children from a wide range of cultures throughout the world. It appears to be wired into the nervous system of our species.”
—Lawrence Kutner (20th century)
