You are asking about Level 2 details used in friction ridge analysis, comparison and evaluation. The answer you (or your teacher?) are looking for is probably:
ridge ending However, you should be aware that many people consider that there are only three Level 2 details, ridge endings, bifurcations and dots... and that the many other Level 2 formations are merely combinations of the three (sometimes 12 are listed)
dot or island
More importantly, you should be aware that identifications are not based JUST on Level 2 "points" in most latent print examinations. To quote my former supervisor, Robert D. Olsen, Sr.:
Some latent print examiners have accepted the concept that friction ridge characteristics are synonymous with the points of identity used to establish the positive identification of a latent print. These examiners hold the view that one friction ridge characteristic, regardless of its configuration and complexity, constitutes only one point of identity. This is an erroneous concept. Friction ridge characteristics and points of identity are two distinct and separate concepts involving the same physical data.
