tubercle
tubercle [Lat.,=little swelling], small, usually solid, nodule or prominence.

In dentistry tubercle refers to the cusp of a tooth. In pathology it describes small morbid growths, particularly the lesions of tuberculosis . In botany it applies to the nodules on the roots or leaves of plants. In entomology the term is used for a compound or supplementary eye and for the nodules on the bodies of certain insects. |
