What term describes a dense network of nerves and capillaries?

The term "plexus" accurately describes a dense network of nerves and capillaries. In anatomical contexts, a plexus refers to an intricate web of interwoven fibers, often involving both nerves and blood vessels, that work together to supply and coordinate various body parts. Examples include the brachial plexus that innervates the upper limb and the choroid plexus found in the brain, which is involved in the production of cerebrospinal fluid.

The other terms, while related to the nervous system, do not convey the same complexity or network structure. "Ganglia" refers specifically to clusters of neuronal cell bodies located outside the central nervous system. "Nerve endings" usually denote the terminal parts of nerves where they interact with muscles or sensory receptors, but do not imply the complex interrelations suggested by a plexus. "Neural connectors" is not a widely recognized term in anatomy or neuroscience. Therefore, the choice of "plexus" most accurately captures the concept of a dense network of nerves and blood vessels.
