  TIBIAL TUBERCLE FRACTURES
The extensor mechanism consists of the tibial tubercle, the patellar tendon, the patella, the quadriceps tendon, and the quadriceps muscle.
As the quadriceps muscle contracts (shortens), it pulls on the quadriceps tendon, the patella, the patellar tendon, the tibia tubercle, and the tibia to move the knee from a flexed (bent) position to an extended (straight) position.
Tibial tubercle fractures usually occur in adolescents and typically occur at the growth plate of the proximal (upper) tibia.

 Genital tubercle   (Site not responding. Last check: 2007-10-19)
A genital tubercle is a body of tissue which forms in the ventral, caudal region of mammalian embryos of both sexes, and eventually develops into a phallus.
In the human fetus the genital tubercle develops around week 4 of gestation, and by week 9 becomes recognizably either a clitoris or penis.
The genital tubercle is sensitive to dihydrotestosterone and rich in 5-alpha-reductase, so that the amount of fetal testosterone present after the second month is a major determinant of phallus size at birth.

The aim of this study is to determine the degree of anatomic variation in the dimensions of Chassaignac’s tubercle (the anterior tubercle of the transverse process of C6) and propose rational modifications to the classic technique that might reduce the risk of complications while improving the success rate of the block.
To better define the width of the tubercle (superior-inferior dimension), we employed multiplanar reformatted CT images of C6 in six of the patients in the study chosen at random.
Chassaignac’s tubercle is 13 ± 4 mm deep and 19 ± 4mm lateral to the lateral cricoid margin.

 Australian Endocrine Surgeons - August 2003 Newsletter: The Tubercle of Zuckerkandl
The tubercle of Zuckerkandl is a distinct anatomical entity that was first described by Emil Zuckerkandl in 1902.
The description, and the clinical significance of the tubercle, was lost to endocrine surgeons until the last decade when the tubercle was “rediscovered” by a number of authors.
The importance of the tubercle of Zuckerkandl is that, if not looked for and removed during thyroid surgery, it may be a source of persistent unrelieved symptoms or recurrence.

 bovine tubercle bacillus, The British Journal of Biomedical Science - Find Articles
Abstract: The bovine tubercle bacillus has always been eclipsed by the much higher incidence and the social and economic importance of its human cousin, as well as by the clinical unimportance of differentiating between the two.
However, the agent responsible could not be demonstrated by microscopy because, as we now know, the tubercle bacillus has a wax-like coat that resists staining by aniline and other dyes used to stain bacteria for microscopic examination.
During the late 19th century, attempts to grow the tubercle bacillus on the artificial culture media available proved unsuccessful until 1882, when Koch grew it, from both human and animal material, on heat-coagulated blood serum.l4 He called the organism the `Tuberkelbazillus' and demonstrated its causal relationship to tuberculosis.

The tibial tubercle is vulnerable to injury during the transitional phase of closure.

 BioMed Central | Full text | Insights into the evolutionary history of tubercle bacilli as disclosed by genetic ...
canettii", a rare phenotypically unusual tubercle bacillus, appears to be closest to the common progenitor of the MTBC [17,18].
It is thought that members of the PE/PPE multigene families might frequently undergo genetic remodelling by gene duplication, recombination, and/or strand slippage mechanisms because of the presence of a large number of repeat sequences within these genes [2].
This picture contrasts with the situation that seems to have prevailed in the very early history of the tubercle bacillus in which a significant rate of DNA exchanges were allowed, most likely through intragenomic recombination and horizontal gene transfer [19].
