adult synganglion

The synganglion constitutes the entire central nervous of the tick. There is no separate brain or ventral nerve chord. The synganglion is located in the midventral region of the body immediately posterior to the genital pore in adults or the location where the genital pore will form in immature specimens. The synganglion is a small white organ approximately 0.5 mm wide by 0.4 - .05 mm long. The esophagus penetrates through the synganglion, entering more or less from the anterior ventral side and emerging near theposterior dorsal side of the organ.
