Summary
This study details variations in the posterior intercostal neurovascular bundle, including rare fetal connecting branches and nerve communications. Understanding these anatomical variations is crucial for thoracic procedures and intercostal nerve blocks.
Area of Science:
- Anatomy
- Thoracic Surgery
Background:
- The posterior intercostal neurovascular bundle's anatomical structure is complex.
- Variations in this bundle can impact clinical procedures.
Purpose of the Study:
- To investigate and document variations in the posterior intercostal neurovascular bundle.
- To highlight anatomical anomalies relevant to thoracic interventions.
Main Methods:
- Dissection of 12 cadaveric posterior intercostal spaces (1st-11th).
- Observation of arrangement, course, relations, and patterns of neurovascular structures.
Main Results:
- Identified four types of neurovascular bundle arrangements.
- Documented a fetal connecting branch between veins and nerves.
- Observed variations in artery-nerve relations, white rami communicantes, and intrathoracic nerves of Kuntz.
Conclusions:
- Knowledge of posterior intercostal neurovascular bundle variations is essential for intercostal nerve blocks.
- Awareness of fetal connecting branches and nerve communications aids thoracic surgical approaches.

01:17Gross Anatomy of the Lungs
1.4K
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...

01:15Thoracic Aorta
256
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,...

01:25Muscles of the Thorax
1.1K
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...

01:16Spinal Cord: Cross-sectional Anatomy
1.5K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:27Anatomy of the Heart
103.2K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

01:20The Thoracic Cage: Ribs
2.0K
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal...
