    Sspine doesn’t make sense here at all. I assume OP meant esophagus/ gullet.

      It says spines, rather than spine. The esophagus is covered in spines (think like the spines on a porcupine, not a backbone).

            More a biology lesson. It’s the scientific word for the appendage. Human’s — I believe all mammals as well — have them lining our lower intestines. They help us absorb nutrients by increasing surface area.

            The word itself, papillae, just means “a small, rounded part which protrudes from an organ/ nipple” from Latin.
