Right lobar bronchi and bronchus intermedius

Bronchi lobares dextri et bronchus intermedius

Origin
Arise from the right main bronchus as the eparterial superior lobar bronchus and the bronchus intermedius
Insertion
The bronchus intermedius subsequently divides into the middle and inferior lobar bronchi
Function
Supplies air to the three right pulmonary lobes (upper, middle, lower)
Innervation
Pulmonary plexus
Movement & chain
Lobar airway compliance and caliber change during breathing
Palpation
Auscultated over right anterior, lateral, and posterior thorax
Clinical
Bronchus intermedius obstruction collapses both middle and lower lobes. Middle lobe syndrome (chronic recurrent atelectasis of the middle lobe due to lymph node compression).
Segmental innervation
T2-T5 spinal levels
In clinical practice
Focused chest auscultation, bronchoscopic intervention for lobar obstruction, targeted chest physiotherapy
Region in the model
