Yes, the ring finger has nerves that supply sensation and movement. The primary nerves responsible for this are the ulnar nerve and the median nerve, which provide sensory innervation and motor control to the muscles in the hand. Damage or injury to these nerves can affect the function and sensation of the ring finger.
Annelid worms do not have a nerve ring like those found in some other invertebrates, such as echinoderms. Instead, they possess a centralized nervous system that includes a ventral nerve cord and a series of segmentally arranged ganglia. These ganglia function similarly to a nerve ring by coordinating movement and sensory responses, but they are distributed along the length of the body rather than forming a single ring structure.

The vagus nerve is primarily parasympathetic in its function.

One animal that has a nerve ring is a hydra. The hydra is a fresh water animal with a tubular body and tentacles around the mouth.
A peripheral nerve function test is performed to test the nerve function in the peripheral nerve. This test is often performed to when there is pain or weakness in the limbs.
