Gross Anatomy of the Lungs01:17

Gross Anatomy of the Lungs

3.7K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

Pleura of the Lungs01:13

Pleura of the Lungs

5.2K
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Cystic Fibrosis: Pathogenesis

595
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

COPD: Pathogenesis and Clinical Features

1.6K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

3.9K
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Respiratory System Abnormal Finding II: Palpation and Auscultation

1.1K
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Area of Science:

  • Pulmonary Anatomy and Pathology

Background:

  • Pulmonary fissures are anatomical structures within the lungs that separate lobes.
  • Variations like accessory and incomplete fissures can occur.
  • These variations are frequently overlooked in routine radiological assessments.

Purpose of the Study:

  • To review the anatomy, histology, and disease processes associated with pulmonary fissures.
  • To emphasize the clinical significance of accessory and incomplete pulmonary fissures.

Main Methods:

  • Literature review of anatomical and pathological studies on pulmonary fissures.
  • Analysis of clinical case reports and imaging studies highlighting the importance of fissure variations.

Main Results:

  • Accessory and incomplete fissures represent common anatomical variations.
  • These variations can mimic or obscure disease processes on imaging.
  • Clinical implications include potential misdiagnosis and altered disease staging.

Conclusions:

  • Accessory and incomplete pulmonary fissures possess significant clinical importance.
  • Recognition of these anatomical variations is vital for accurate diagnosis and prognosis.
  • Enhanced understanding of fissure anatomy benefits oncologists, interventional pulmonologists, and thoracic surgeons.
