TUBEROSITY - 2 reference results
In anatomy, a tubercle is a round nodule, small eminence, or warty outgrowth found on bones, skin, or within the lungs in tuberculosis.
Types
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.In the mouth
Tubercles are usually found behind the last molar in the upper jaw, covered by the gum. Surgery can be done to make tubercles less prominent.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 inferiorly.On the legs
The tibia, more commonly known as the shinbone or shankbone, has a prominent tubercle--the tibial tuberosity--on its anterior surface, distal to the medial condyle. It creates a bony prominence just below the patella, and can be easily located with the fingers. It creates an attachment point for the ligamentum patellae, or patellar ligament.On ribs
- ''See tubercle (rib)
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.On the genitals
The genital tubercle is a small bump that eventually develops into a penis on a male human fetus and into a clitoris if the fetus is female.References
