- n. A small knoblike prominence or excrescence, whether natural or morbid
- n. A small mass or aggregation of morbid matter; especially, the deposit which accompanies scrofula or phthisis. This is composed of a hard, grayish, or yellowish, translucent or opaque matter, which gradually softens, and excites suppuration in its vicinity. It is most frequently found in the lungs, causing consumption.

Running obliquely downward and medialward from the tubercle is the intertrochanteric line (spiral line of the femur); it winds around the medial side of the body of the bone, below the lesser trochanter, and ends about 5 cm. below this eminence in the linea aspera.
A prominence, of variable size, occurs at the junction of the upper part of the neck with the greater trochanter, and is called the tubercle of the femur; it is the point of meeting of five muscles: the Glutæus minimus laterally, the Vastus lateralis below, and the tendon of the Obturator internus and two Gemelli above.
The volar surface is concave above, and elevated at its lower and lateral part into a rounded projection, the tubercle, which is directed forward and gives attachment to the transverse carpal ligament and sometimes origin to a few fibers of the Abductor pollicis brevis.
In the female a deep groove forms around the phallus and separates it from the rest of the cloacal tubercle, which is now termed the genital tubercle.
The adductor tubercle, which is situated on the upper and back part of the medial epicondyle, gives attachment to the round tendon of the adductor magnus, and marks the level of the epiphysial line and of the upper limit of the trochlear surface of the femur.
TB is caused by the bacterium Mycobacterium tuberculosis, which is also called a tubercle bacillus.
This containing structure, called a tubercle, physically protects the bacteria from being destroyed by the immune system.
The idea, known as tubercle technology, is being considered for airplanes, submarines and wind turbines, but the first product on the market is the Altra Air ceiling fan from Envira-North Technologies.
Tuberculosis, or 'TB', is a disease caused by a germ (called the tubercle bacterium or Mycobacterium tuberculosis).
