Neuron
Neuron can be defined as excitable
cell that usually carries, processes and transmit impulses or electrical
signals. Thus, they are known to be basic unit of the nervous system which
includes the spinal cord and brain. However, the signals between s neurons occur
via certain connections called synapses.
They replace the lost ions by active uptake through active transport
of ions from the surrounding waters. This is exhibited in freshwater fishes that
actively take in these ions through the gills. Most of the ions involved in osmoregulation in freshwater are those of Na+ and Cl-.
