From: The first data on the innervation of the lophophore in the rhynchonelliform brachiopod Hemithiris psittacea: what is the ground pattern of the lophophore in lophophorates?

Fig. 8

Three-dimensional reconstructions of the cross nerves and the second accessory nerve in Hemithiris psittacea. Volume rendering of some nerve elements stained against alpha acetylated-tubulin (glow). a The cross nerves (cn) and their branches (bcn) viewed from the brachial fold. b The cross nerves viewed from the top. Cross nerves skirt the accessory brachial nerve. c The cross nerves and the accessory brachial nerve viewed from the longitudinal axis of the brachium. d A portion of the second accessory nerve. e A portion of the second accessory nerve: volume rendering of nerve elements (glow), combined with volume rendering of elements stained with phalloidin (grey). Abbreviations: bcn – branches of cross nerves; cn – cross nerve; it – inner tentacle; mn – main brachial nerve; ot – outer tentacle; sa – second accessory nerve
