Is tubercle and granuloma the same?
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 the tubercle do?
In the skeleton of humans and other animals, a tubercle, tuberosity or apophysis is a protrusion or eminence that serves as an attachment for skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone.
What is hard tubercle?
sealed up in hard, nodular tubercles. 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.
How are tubercles formed?
The infection is spread like a cold, mainly through airborne droplets breathed into the air by a person infected with TB. The bacteria causes formation of small tissue masses called tubercles. In the lungs these tubercles produce breathing impairment, coughing and release of sputum.
What’s the difference between tuberosity and tubercle?
A tubercle is a small rounded prominence, often a site of tendon or ligament attachment e.g. adductor tubercle of the femur. A tuberosity is larger, found in varying shapes and often rough in texture.
Where are tubercles found?
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. The term tubercle is less commonly used to refer to skin irritation resulting from a tuberculosis (TB) infection.
Is trochanter and tuberosity the same?
Trochanter – A large prominence on the side of the bone. Some of the largest muscle groups and most dense connective tissues attach to the trochanter. The most notable examples are the greater and lesser trochanters of the femur. Tuberosity – A moderate prominence where muscles and connective tissues attach.
Is trochanter and tubercle same?
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals, the trochanters serve as important muscle attachment sites.
Is tubercle a bone process?
A hole is an opening or groove in the bone that allows blood vessels and nerves to enter the bone….Learning Objectives.
