Within the human body there are numerous sites where tubercles develop. On bones they are generally the sites of muscle insertions. Within the lungs and on the genitals, tubercles are sites of disease.

On the arms
The humerus of the upper arm has two tubercles, the greater tubercle and the lesser tubercle. These are situated at the proximal end of the bone, that is the end that connects with the scapula. The greater/lesser tubercule are located from the top of the acromion laterally and down.

In the lungs
Tubercles in the lungs develop as a result of infection by the Mycobacterium tuberculosis bacterium. Granulomas form in the infected tissue and undergo necrosis in the centre. Tubercles are also known as tuberculous nodules.
