Figure 8From: Selective neuronal staining in tardigrades and onychophorans provides insights into the evolution of segmental ganglia in panarthropodsDiagrams showing the organisation of the tardigrade nervous system. Reconstructions of nerve tracts are based on anti-tubulin immunolabelling in Macrobiotus cf. harmsworthi. Anterior is up. (A) Ventral view. (B) Lateral view. Abbreviations: al, anterior leg nerve; as, anterolateral sensory field; br, brain; cl, cloacal nerves; cn, connective; dn, dorsolateral nerve tract; ga1–ga4, trunk ganglia 1 to 4; ic, inner connective; ip, interpedal commissure; le1–le4, legs 1 to 4; lg, leg ganglion; ln, lateral nerve tract; ne, neurites supplying the peribuccal lamellae; nr, nerve ring innervating the peribuccal lamellae; oc, outer connective; pg, peripheral ganglion; pl, posterior leg nerve; pn, peripheral nerve; ps, posterolateral sensory field.Back to article page
