Question

Quizplus · Accepted Answer

A plexus is a network of nerves formed by the branching and merging of several spinal nerves, allowing them to reorganize and divide into smaller peripheral nerves. This helps to facilitate more efficient and coordinated movement and sensory function in the body. Examples of plexuses include the brachial plexus in the upper extremity and the sacral plexus in the lower extremity.
