The Central Projection of Cephalic Mechanosensory Axons in the Haematophagous Bug Triatoma infestans

Mostrar todas las versiones(3)

The projections of mechanosensory hairs located on the dorsal and lateral head of the adult haematophagous bug Triatoma infestans were analyzed by means of cobalt filling. Axons run into the anterior and posterior tegumentary nerve and project through the brain to the ventral nerve cord. The fibres...
