The cone photoreceptor’s synaptic ending is called?

Explanation:
In the retina, photoreceptors communicate with bipolar cells through specialized synaptic endings. Cones have a synaptic ending called a pedicle, which is a stalk-like terminal rich in ribbon synapses that forms connections with multiple bipolar cells in the outer plexiform layer. This setup supports rapid and precise transmission of visual signals, including color information. The other terms don’t fit cone endings: a spherule is the rod’s terminal, a bouton is a more general term for synaptic endings, and a terminal is too generic.
