In anatomy, a tubercle is a round nodule, small eminence, or warty outgrowth found on bones, skin, or within the lungs in tuberculosis. A wart (also known as verruca) is generally a small rough Tumor, typically on hands and feet but often other locations that can resemble a Cauliflower Bones are rigid organs that form part of the Endoskeleton of Vertebrates They function to move support and protect the various organs of the body produce Tuberculosis (abbreviated as TB for tubercle bacillus or T u' b' erculosis Bacillus --> is a common

Types
Within the human body there are numerous sites where tubercles develop. On bones they are generally the sites of muscle insertions. Muscle (from Latin musculus, diminutive of mus "mouse" is contractile tissue of the body and is derived from the 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. [1]
On the arms
The humerus of the upper arm has two tubercles, the greater tubercle and the lesser tubercle. The humerus is a Long bone in the Arm or Forelimb that runs from the Shoulder to the Elbow. The greater tubercle of the Humerus is situated lateral to the head of the humerus and posteriolateral to the Lesser tubercle. The lesser tubercle of the Humerus, although smaller is more prominent than the Greater tubercle: it is situated in front and is directed medialward and forward These are situated at the proximal end of the bone, that is the end that connects with the scapula. In Anatomy, the scapula, omo, or shoulder blade, is the Bone that connects the Humerus (arm bone with the Clavicle (collar 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. The tibia, shinbone, or shankbone is the larger and stronger of the two Bones in the Leg below the Knee in vertebrates and connects Narrow below where the anterior surfaces of the condyles of the Tibia end in a large oblong elevation the tuberosity of the tibia, which gives attachment to the Ligamentum 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. The knee is the lower extremity Joint connecting the Femur, Patella, and the Tibia.
On ribs

In the lungs
Tubercles in the lungs develop as a result of infection by the Mycobacterium tuberculosis bacterium. The tubercle of a Rib is an eminence on the posterior surface at the junction of the neck and body of the Rib, and nearer the lower than the upper border Mycobacterium tuberculosis is the Bacterium that causes most cases of Tuberculosis. Granulomas form in the infected tissue and undergo necrosis in the centre. Necrosis (in Greek Νεκρός = "dead" is the name given to unnatural Death of cells and living tissue. 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. The penis (plural penises, penes A fetus (or foetus or fœtus) is a developing Mammal or other Viviparous Vertebrate, after the Embryonic stage and
