Answer:

The skeletal rod of a secondary gill bar is called secondary gill rod. The primary gill bars are interconnected by a system of transdverse bars or synapticula which impart a basket like appearance to the pharynx similar to the branchial sac of tunicates. A synapticulum also contains a blood vessel and a skeletal rod.
