- The blood supply of the scaphoid comes from the radial artery, feeding the bone on the dorsal surface near the tubercle and scaphoid waist.
- When this happens, the bacteria become encapsulated in tiny tubercles (round lesions) usually in the lungs which may be seen on a chest X-ray.
- Responding to the invasion, macrophages may huddle with other immune cells to form little nodules called granulomas, or tubercles.
- Tuberculoma is a mass of granulation tissue made up of a conglomeration of microscopic small tubercles.
- Even on the bare question of the presence or absence of tubercle in a lung it often fails us; on questions of the age, extent, distribution and histological character of the tuberculous lesions it can tell us little.
- The disease causes these tubercles to become yellow and spongy and coughing fits causes them to be spat out by the sufferer.
- In the male, the genital tubercle is located adjacent to and caudal to the umbilicus, whereas the genital tubercle in the female is located just ventral to the tail.
- Its fibers pass dorsally from an extensive anterior attachment to insert on the pharyngeal raphe, the pharyngeal tubercle of the occipital bone.
- A terminal segment includes a tubercle that projects dorsally and an anus.
- The tubercles have rounded surface and irregular shape.
