just to revise--

CN with longest intracranial course -- trochlear n.
CN with longest extracranial course --vagus n.
CN which is the largest and thickest -- trigeminal n.
CN with dorsal exit -- trochlear n.
CN which is the smallest -- olfactory n.

*The information provided is very correct.
I am further putting some additional information

* Trochlear nerve is the only nerve to go dorsally and then coming to the ventral aspect of brain...
...It thus gains some additional length (while going dorsally) and becomes the nerve with longest intra-cranial course !
*Abducent nerve has the longest intra-cranial SUB-ARACHNOID course!!
What does it mean....? It means that - Though Trochlear nerve has got the longer intracranial course than Abducent....but Abducent stays in SUB-ARACHNOID space for a longer distance intracranially!!!
