The tongue is a muscular hydrostat that forms part of the floor of the oral cavity. The left and right sides of the tongue are separated by a vertical section of fibrous tissue known as the lingual septum.

Down the middle of the sublingua is a thick strengthening rod called the plica mediana or lytta, which connects the sublingua to the underside of the tongue, [7] [8] [9] and is part of the lingual septum (septum of the tongue). [8]
