WebBipolar cells are one of the main retinal interneurons and provide the main pathways from photoreceptors to ganglion cells, i.e. the shortest and most direct pathways between the input and output of visual signals in the retina. What is a bipolar cell in anatomy? WebBipolar nerve cell from the spinal ganglion of the pike. A bipolar neuron, or bipolar cell, is a type of neuron that has two extensions (one axon and one dendrite ). Many bipolar cells are specialized sensory neurons for the transmission of sense.
