Number and distribution of neurons in leech segmental ganglia

The number of neurons and their distribution were determined for specific segmental ganglia from the nerve cord of four different species of leech. Quantitative data were obtained by using computer‐aided techniques for the analysis of nerve structure from serially sectioned or whole‐mounted tissue. The species studied were Hirudo medicinalis, Macrobdella decora, Haemopis marmorata (family Hirudinidae), and Haementeria ghilianii (family Glossophoniidae).
