What is Eparterial bronchus?

What is Eparterial bronchus?

The eparterial bronchus is a synonymous term for the right superior lobar bronchus. Its name is derived from the bronchus being the only one originating superior to the level of the pulmonary artery.

Which lung has an Eparterial bronchus?

right lung
The eparterial bronchus (right superior lobar bronchus) is a branch of the right main bronchus given off about 2.5 cm from the bifurcation of the trachea. This branch supplies the superior lobe of the right lung and is the most superior of all secondary bronchi….

What does Hyparterial mean?

Medical Definition of hyparterial : situated below an artery specifically : of or being the branches of the bronchi given off below the pulmonary artery.

What is segmental bronchus?

Segmental bronchi are the ‘generation’ of bronchi produced by the first division of the bronchial tree after the lobar bronchi. Hence, they are also the bronchi resulting from the second division of the bronchial tree after the tracheal bifurcation. segmental bronchi (left lung) histology. bronchopulmonary segments.

What is eparterial and Hyparterial?

A hyparterial bronchus is any bronchus originating inferior to the level of the pulmonary artery. Conversely, the right superior lobar bronchus can be referred to by its anatomical relationship to the pulmonary arteries as being eparterial.

What is tracheal bronchus?

Tracheal bronchus is an aberrant bronchus that arises most often from the right tracheal wall above the carina and is the result of an additional tracheal outgrowth early in embryonic life. Its incidence ranges between 0.1 and 5%.

What does the segmental bronchi do?

The segmental bronchi divide into many primary bronchioles that divide into terminal bronchioles, each of which then gives rise to several respiratory bronchioles, which go on to divide into and terminate in tiny air sacs called alveoli.

Where does the post eparterial bronchus come from?

The pre-eparterial bronchus (Pre-EAB) arises from the right mainstem bronchus proximal to the origin of the right upper lobe bronchus. The post-eparterial bronchus (Post-EAB) arises distal to the origin of the right upper lobe bronchus.

Which is the only bronchus with a specific name?

It arises above the level of the right pulmonary artery, and for this reason is named the eparterial bronchus. All other distributions falling below the pulmonary artery are termed hyparterial . The eparterial bronchus is the only secondary bronchus with a specific name apart from the name of its corresponding lobe.

Is the eparterial bronchus part of the trachea?

Anatomical terminology. [edit on Wikidata] The eparterial bronchus (right superior lobar bronchus) is a branch of the right main bronchus given off about 2.5 cm from the bifurcation of the trachea.

Who is the inventor of the eparterial bronchus?

The classification of eparterial and hyparterial is attributed to Swiss anatomist and anthropologist Christoph Theodor Aeby, and is central to his model of the anatomical lung. He presented this model in a monograph titled, “Der Bronchialbaum der Säugethiere und des Menschen, nebst Bemerkungen über den Bronchialbaum der Vögel und Reptilien”.
