Identification of cardio-acceleratory neurons in the thoracic ganglion of the isopod crustacean Bathynomus doederleini.
We identified cell bodies of the first and second cardio-acceleratory nerves (CA1 and CA2) in the second and third thoracic ganglia of Bathynomus doederleini. Each cell body gives rise to a single axon, which diverges into two major processes in each case. One of the two major axon processes from the second thoracic ganglion runs to the heart via the third root as CA1, while that from the third thoracic ganglion runs as CA2. The other axon process runs forward to the anterior ganglion in both cases.
