What structure is called a tubercle?
Tubercle – A small, rounded prominence where connective tissues attach. Examples include the greater and lesser tubercle of the humerus.
What is a tubercle anatomy?
A tubercle is a small rounded point of a bone. It also refers to a nodule attached to bone, mucous membrane (moist layer lining parts of the body), or skin.
How is a tubercle formed?
Tubercles are nodules that contain caseous necrosis, which form in the lungs as a result of an infection with Mycobacterium tuberculosis in the patients with tuberculosis. Granulomas form in the infected tissue and undergo necrosis in the centre. Tubercles are also known as tuberculous nodules, or tuberculomas.
What does a tubercle look like?
A tubercle usually consists of a centre of dead cells and tissues, cheeselike (caseous) in appearance, in which can be found many bacilli. This centre is surrounded by radially arranged phagocytic (scavenger) cells and a periphery containing connective tissue cells.
Where is tubercle located?
On a rib, tubercle is an eminence on the back surface, at the junction between the neck and the body of the rib. It consists of an articular and a non-articular area.
Which landmark is found on the anterior surface of the femur?
The lesser trochanter is a small, bony prominence that lies on the medial aspect of the femur, just below the neck. A single, powerful muscle attaches to the lesser trochanter. Running between the greater and lesser trochanters on the anterior side of the femur is the roughened intertrochanteric line.
Where is a tubercle located?
What is a tubercle quizlet?
Tubercle. A small, rounded projection. Tuberosity. Large rounded projection; may be roughened.

What is tubercle root?
noun A small tuber-like growth produced upon the roots of certain plants, especially legumes, by bacteria which live in a symbiotic relation with the plants and enable them to assimilate free nitrogen.
Is tubercle a bone process?

What landmark is found on the diaphysis of the femur?
Trochanter ~ The greater and lesser trochanters are unique to the femur. Identify the landmark found on the diaphysis of the femur. Linea aspera ~ The linea aspera is an elevated ridge found on the diaphysis of the femur. It serves as a site of muscle attachment.
Who are the authors of the anatomy of tubercles?
The anatomy of tubercles: A corrosion study in a fresh water estuary Dedicated to Professor Dr. Wolfgang Sand on the occasion of his 60th birthday R. I. Ray, J. S. Lee, B. J. Little* and T. L. Gerke
How are tubercles formed in a drinking water system?
In general, the tubercles formed in DSH are similar in morphology and mineralogy to corrosion products described for carbon steel and cast iron exposed to treated waters in decades-old drinking water and cooling water systems. DSH tubercles are unique in several structural details.
How is the mineralogy of a tubercle analyzed?
Tubercles (not embedded) were examined using environmental scanning electron microscopy (ESEM)coupledwithenergydispersiveX-rayspectrometry(EDS) as previously described [5]. The mineralogy of the tubercles was analyzed using a Siemens D-500 automated diffractometer system using a Cu Ka radiation at 30mA and 40kV.
How big are the droplet nuclei of tuberculosis?
M. tuberculosis , and the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lungs (Figure 2.2). M. tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter.
