Where is tubercle located in the body?
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.
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.

What is the structure of tubercle?
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.
What is the tubercle of humerus?
The greater tubercle is the most lateral portion of the proximal end of the humerus. It consists of three smooth and flat impressions at the posterosuperior aspect for the attachment of muscles. From superior to inferior, the muscles that attach at these impressions are the: supraspinatus.
How do you treat tubercle?
Patients with strongly suspected or confirmed tuberculosis undergo an initial treatment period that lasts two months and consists of combination therapy with isoniazid, rifampicin, ethambutol, and pyrazinamide. These drugs may be given daily or two times per week.
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.
What is tubercle?
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.
Where is the Diaphysis?
The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult.
What is hard tubercle?
hard tu·ber·cle (hahrd tū’bĕr-kĕl) A tubercle lacking necrosis.
Where is the tibial tubercle?
The tibial tubercle is a bony bump on the upper part of the shin where the patellar tendon attaches the quadriceps muscles (or quads) to the leg. A tibial tubercle fracture is a break or crack at this location, which usually occurs as a result of the patellar tendon pulling off a piece of the bone.
What bone contains the greater tubercle?
the humerus
The margin of the smooth area of the head is the anatomical neck of the humerus. Located on the lateral side of the proximal humerus is an expanded bony area called the greater tubercle.
Is it greater tubercle or tuberosity?
The main difference between tuberosity and tubercle is that tuberosity refers to a slightly larger lump on bones, but tubercle refers to the smaller lump. Some of the examples of tuberosity are the greater tuberosity of the humerus and the ischial tuberosity of the hip bone.
What is the difference between a tubercle and tuberosity?
Tubercle implies a smooth rounded elevation on a bone, such as the greater and lesser tubercles of the humerus. A tuberosity is a rough, elevated area of the bone such as the tibial tuberosity,…
What is the function of a tubercle?
A tubercle is a small, round nodule that grows out of the skin, bone, or membranes. Tubercles can develop in several sites on the body, including the mouth, arms, legs, ears, and lungs. When attached to bone, tubercles serve the function of connecting ligaments to muscle.
How is ‘tuberosity’ and ‘tubercle’ different?
The main difference between tuberosity and tubercle is that tuberosity refers to a slightly larger lump on bones, but tubercle refers to the smaller lump . Some of the examples of tuberosity are the greater tuberosity of the humerus and the ischial tuberosity of the hip bone.
What is a tubercle anatomy?
In anatomy, a tubercle is any round nodule, small eminence, or warty outgrowth found on external or internal organs of a plant or an animal.
