Corpus: Cystic plexus

1. Definition

The cystic plexus is a nerve plexus that innervates the gallbladder and bile ducts.

2. Anatomy

The cystic plexus contains parasympathetic, sympathetic, and sensory components. Parasympathetic fibres originate from the anterior and posterior vagal trunks of the vagus nerve, while sympathetic fibres come from the thoracic spinal segments Th7 to Th9. Additionally, the right phrenic nerve provides sensory fibres to the plexus.

3. Function

The cystic plexus regulates the motor function of the bile ducts, influences the activity of their sphincters, and supplies the bile ducts with sensory information.
