terminal descending limb of the lateral fissure

terminal descending limb of the lateral fissure (ltftdl)

The term terminal descending limb of the lateral fissure (ltfdl) refers to one of two branches at the end of the lateral fissure (ltf) in the human. Identified by dissection, its appearance is variable. In about half of cases it is identical to the transverse temporal limb of the lateral fissure (ltftt). The other branch is the terminal ascending limb of the lateral fissure (ltfal) ( Ono-1990 ). The ltfdl is not found in the macaque ( Martin-2000 ) nor in the smooth cerebral cortex (CTX) of the rat and mouse ( NeuroNames ). Udated 27 Aug 2024.

Also known as: posterior descending limb of the lateral sulcus, descending terminal ramus of Sylvian fissure, terminal descending limb of the lateral fissure, terminal descending limb of sylvian fissure
