Which organelle of the cell was previously named as peri-canalicular body.

The answer is lysosomes.

Initially lysosomes were named as peri-canalicular dense bodies. This name was based on their location inside the cell.

Peri means “around” and canalicular means “canal-like”. These organelles were found near Golgi complex and ER which is a canal-like in appearance. Therefore, this name was given.
