What do you think the word tubercle means?
1: a small knobby prominence or excrescence especially on a plant or animal: nodule: such as. a: a protuberance near the head of a rib that articulates with the transverse process of a vertebra.
What does the inside of a tubercle consist of?
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.
Is a tubercle the same as a granuloma?
…the granulomas formed are called tubercles. A tubercle usually consists of a centre of dead cells and tissues, cheeselike (caseous) in appearance, in which can be found many bacilli.
What is a bony process?
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body.
What is a Trochlea in anatomy?
Medical Definition of trochlea: an anatomical structure resembling a pulley: as. a: the articular surface on the medial condyle of the humerus that articulates with the ulna. b: the fibrous ring in the inner upper part of the orbit through which the tendon of the superior oblique muscle of the eye passes.
What does process mean in anatomy?
Process: In anatomy, a projection from a structure. For example, the process of the mandible is the part of the lower jaw that projects forward.
What does a tubercle do?
In the human skeleton, a tubercle or tuberosity is a protrusion 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 the difference between tubercle and tuberosity?
Tuberosity – A moderate prominence where muscles and connective tissues attach. Tubercle – A small, rounded prominence where connective tissues attach. Examples include the greater and lesser tubercle of the humerus.
Where is the exactly 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.
Why are granulomas bad?
Typically, granulomas are noncancerous (benign). Granulomas frequently occur in the lungs, but can occur in other parts of the body and head as well. Granulomas seem to be a defensive mechanism that triggers the body to “wall off” foreign invaders such as bacteria or fungi to keep them from spreading.
How does a granuloma form?
Granulomas form when immune cells clump together and create tiny nodules at the site of the infection or inflammation. A granuloma is the body’s way: to contain an area of bacterial, viral or fungal infection so it can try to keep it from spreading; or. to isolate irritants or foreign objects.
What do granulomas contain?
The granuloma contains mostly blood-derived macrophages, epithelioid cells (differentiated macrophages) and multinucleated giant cells (also known as Langhans giant cells), surrounded by T lymphocytes [8, 9]. Caseous granulomas are typical of tuberculosis.
What are the major bone markings?
There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).
What is the purpose of bone markings?
Bone markings are projections and depressions found on bones , which help us to identify the location of other body structures, such as muscles.
