Location and Orientation of the Heart01:13

Location and Orientation of the Heart

4.1K
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Thoracic Aorta01:15

Thoracic Aorta

665
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

Muscles of the Thorax01:25

Muscles of the Thorax

2.2K
The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It...

Pleura of the Lungs01:13

Pleura of the Lungs

2.8K
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...

Gross Anatomy of the Lungs01:17

Gross Anatomy of the Lungs

2.5K
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...

The Thoracic Cage: Sternum01:17

The Thoracic Cage: Sternum

3.0K
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid...

Area of Science:

  • Thoracic anatomy and physiology
  • Cardiopulmonary medicine
  • Congenital chest wall deformities

Background:

  • The mediastinum is the central thoracic cavity housing vital cardiopulmonary organs.
  • Its structural integrity is crucial for cardiovascular and respiratory function.
  • Congenital chest wall deformities, pectus excavatum and pectus carinatum, are common and affect mediastinal function.

Purpose of the Study:

  • To elucidate the anatomical and physiological role of the mediastinum.
  • To examine the impact of pectus excavatum and pectus carinatum on the mediastinum.
  • To correlate chest wall deformities with cardiopulmonary dysfunction.

Main Methods:

  • Review of anatomical and physiological principles of the mediastinum.
  • Analysis of literature on pectus excavatum and pectus carinatum.
  • Correlation of chest wall deformities with reported clinical manifestations.

Main Results:

  • Pectus excavatum and pectus carinatum represent 90% of chest wall deformities.
  • These conditions are associated with significant respiratory distress and cardiovascular dysfunction.
  • Mediastinal compromise directly impacts cardiopulmonary system performance.

Conclusions:

  • Understanding mediastinal anatomy and physiology is key to managing chest wall deformities.
  • Pectus deformities necessitate evaluation for associated cardiopulmonary compromise.
  • Further research can optimize treatment strategies for these conditions.
