Placed on the condyle
Condylion is a real bony point a few millimeters up and forward, and it is the one people expect to be asked for.
Point · Ar
Articulare (Ar)
Not a bone at all: the crossing where the posterior border of the ramus passes the base of the skull.
At Beginner a placement counts as found within 2.9 mm of the reviewed reading.
How to find it
Press a step to be shown it on the ceph.
Common errors
Each figure is the reviewed reading of Articulare (Ar) and a typical miss, on the same ceph, at the distance the mistake usually goes.
Placed where the ramus crosses the wrong shadow
The mastoid and the cranial base both cross the ramus. The base runs forward towards sella; the mastoid does not.
Used in
8 measurements are built on it. Miss it, and every one of them moves.
