[2025-10-01T18:48:12.747115] [PI reasoning] **Choosing the best anatomical answer**

I need to select the best answer regarding the submandibular gland and mylohyoid muscle anatomy. The submandibular gland indeed wraps around the posterior margin of the mylohyoid muscle, which separates it into superficial and deep parts. This gives me a clear answer: the mylohyoid muscle divides the submandibular gland into these lobes. I can provide evidence from reliable sources like Gray's Anatomy to support this and reinforce the information.
