In anatomy or zoology, having two tuberosities or rounded protuberances, especially on bones.
From bi- (two) + tubercular (from Latin tuberculum, 'a small lump or swelling'). This anatomical term describes bones that have exactly two bumpy projections.
Many bones in your body are bitubercular—having two bumps is actually very common in skeletal anatomy because those bumps are where muscles attach. Anatomists had to get specific about counting these bumps to precisely describe different bones.
