Which cells are present in interalveolar septum?
Interalveolar septa The (inter)alveolar septum is the wall between adjacent alveoli. This wall is lined by a simple squamous epithelium (type I cells) and septal cells (type II cells). The connective tissue core of the septum possesses connective tissue cells and reticular and elastic fibers.
What is the term for the opening in the walls of Interalveolar Septa?

Which situation will happen when you have emphysema?
When emphysema develops, the alveoli and lung tissue are destroyed. With this damage, the alveoli cannot support the bronchial tubes. The tubes collapse and cause an “obstruction” (a blockage), which traps air inside the lungs. Too much air trapped in the lungs can give some patients a barrel-chested appearance.
What is Interradicular dentin?
This is a multirooted tooth. The bony septum lying between the roots is called interradicular septum (A). Principal fibers that anchor the tooth to the interradicular septum are called interradicular fibers (B).
What is the function of septum?
The septum separates the atria and ventricles in such a way that it forms a barrier between the heart chambers and this prevents mixing of oxygenated and deoxygenated blood.
Why is it called a septum?
The word “septum” is borrowed from the Latin “saeptum” meaning a “dividing wall or enclosure.”
What is dust cell?

What are the 4 stages of emphysema?

What does fenestration mean in dentistry?
Fenestration is an isolated area in which the tooth root is denuded of bone and the root surface is covered only by periosteum and overlying gingiva. Mucosal fenestration is a clinical entity in which the overlying gingiva or mucosa is also denuded thus the root is exposed to the oral cavity.
What is bone fenestration?
Fenestration is the condition, in which the bony coverage of the root surface is lost, and the root surface is only covered by the periosteum and gingiva. In such lesions, marginal bone is intact. When this bone defect spreads toward the marginal bone, it is called dehiscence.[1]
What is Interradicular Radiolucency?
Introduction. Interradicular radiolucencies include easily recognizable anatomical structures, lesions related to teeth, or cysts and tumors of odontogenic origin. Lateral periodontal cysts are rare intraosseus developmental cysts which form beside a vital tooth.
