The basal ganglia should be called the basal nuclei, and are also referred to as the corpus striatum. This demonstrates one of the problems with studying neuroanatomy as terms seem to overlap. Let's talk about what the basal ganglia are, what they do, some of this terminology and what they have...

The enteric nervous system describes the nerves of the gastrointestinal tract that autonomously regulate much of its function. Sometimes called the second brain it is a complex network of sensory inputs linked to motor outputs organised into two major plexuses running the entire length of the gut.
