Pulmonary Fissures: Anatomy, Imaging, And Clinical Significance
The right lung possesses two anatomical fissures, the horizontal fissure and the oblique fissure. The horizontal fissure separates the upper and middle lobes, while the oblique fissure divides the middle and lower lobes. Radiologically, fissures appear as linear opacities on chest X-rays and CT scans. Surgical procedures involving fissures include fissurectomy and fissurotomy. The fissures demarcate lung segments with specific nomenclature, including epaxon, hypoaxon, preaxon, paraaxon, and metaxon. Abnormalities in fissures can have clinical significance, potentially affecting pulmonary function and contributing to respiratory complications. Advanced imaging techniques such as CT and MRI provide detailed visualization of fissures for diagnostic and characterization purposes. Ongoing research aims to further elucidate the role of fissures in lung function and disease.

Anatomical Fissures of the Lungs: Divide and Conquer
Every now and then, nature throws us a curveball, even when it comes to our anatomy. And the fissures in our lungs are a prime example. These clever folds aren’t just there for show; they’re actually a masterpiece of design.
Picture this: your lungs are like a sponge, soft and squishy. But without some structure, they’d just collapse into a goopy mess. That’s where fissures come in, like architectural ribs that keep your lungs in shape.
There are two main fissures in each lung: the horizontal fissure and the oblique fissure. The horizontal fissure runs across the middle, creating an upper and a lower lobe. The oblique fissure, on the other hand, is more slanted and divides the upper lobe into two more parts: an anterior segment and a posterior segment.
These fissures are more than just lines on a diagram. They actually play a crucial role in how your lungs function. They help direct airflow and blood circulation, ensuring that every nook and cranny of your lungs gets the oxygen it needs.
So, the next time you breathe in deeply, take a moment to appreciate the hidden heroes within your chest: the anatomical fissures of the lungs. They might not be as glamorous as a heart or a brain, but they’re essential for life!

Unraveling the Puzzle of Lung Segments: A Guide to Fissure-Related Lung Segments
Hey there, fellow anatomy enthusiasts! Let’s embark on a journey to decode the intricate world of lung anatomy and explore the fascinating lung segments bounded by fissures. These anatomical landmarks play a crucial role in understanding lung function and diagnosing lung abnormalities.
Fissures: Nature’s Dividers
Think of fissures as the dividers that partition our lungs into smaller compartments. The horizontal fissure runs like an equator across the lungs, separating the upper (epaxon) from the lower lobes (hypoaxon). Meanwhile, the oblique fissure carves a diagonal path, creating the anterior (preaxon) and posterior (paraxon) segments in the upper lobe.
Lung Segments: The Blocks of Building
Within these fissure-defined boundaries, lie distinct lung segments, each serving a specific function. The epaxon (upper lobe) comprises the apical and posterior segments, while the hypoaxon (lower lobe) is divided into apical, medial, lateral, and posterior basal segments.
Unique Identities with a Twist
The preaxon and paraxon segments of the upper lobe are a bit of a quirky pair. The preaxon is shaped like an apron, tucked in front of the hilum, while the paraaxon is a bit more elongated, stretching towards the posterior aspect of the lung.
Metaxon: The Exception to the Rule
Finally, we have the metaxon, an extra lung segment that may or may not grace your lungs. If present, it’s nestled between the preaxon and hypoaxon segments, adding a touch of anatomical variation.
Fissure Abnormalities: A Tale of Medical Importance
