Such landmarks serve as an approximate starting point for a search for the targeted nerve or nerves by needle exploration. The objective of needle exploration is to reach a finite endpoint that indicates the tip of the needle is sufficiently close to the targeted nerve or nerve plexuses. Two distinct types of endpoint exist.
