Background:
Knowledge of the position and grade of accessory fissures and lobes is necessary for appreciation of lobar anatomy and thus locating bronchopulmonary segments.
Methods:
Morphological variations of accessory fissures and lobes of the lungs were studied in 40 pairs of lungs from cadavers.
Results:
Four left-sided lungs and two right-sided lungs showed accessory fissure in the lower lobe. Only one accessory fissure of left lung belongs to grade-ii and the remaining belongs to grade iii. [According to Craig and Walker's fissural classification]
Conclusions:
Awareness regarding accessory fissures and lobes is essential for performing lobectomies, segmental resection, for differential diagnosis and interpreting radiological images.

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Mechanism of Breathing III: The Accessory Muscles
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
