Inter-axillary anastomoses form cross-midline channels that connect lymphatic pathways from one axilla to the other, so they lie across the vertical plane that divides the body into left and right halves—the median-sagittal watershed. This midline crossing allows lymph drainage to reroute if one side is blocked, providing collateral pathways between the two axillary regions. The other descriptions don’t capture that cross-midline connectivity: those options imply horizontal or purely unilateral pathways, or no cross-communication at all.
