Those “spines” are called papillae, for anyone wanting specifics.

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.
