The plexus lying between the longitudinal and circular muscle coats is the _____ plexus.
Answer
myenteric
Explanation
The missing term is **myenteric**. The myenteric plexus, also called Auerbach’s plexus, lies between the longitudinal and circular muscle coats. By contrast, the submucosal plexus (Meissner’s plexus) lies in the submucosa. Correctly locating the plexuses is useful when reasoning about GI wall organization and the neural control described in the lecture. **Key takeaway:** Myenteric is the plexus between the main muscle layers.\n\n**Glossary:**\n- **Myenteric plexus**: Nerve network between the longitudinal and circular muscle layers.\n- **Submucosal plexus**: Nerve network located in the submucosa.
