Nov 21, 2023 · The apex is the highest point of the lung, extending into the thoracic inlet. It is a dome-shaped part of the lung that protrudes above the first costal cartilage and the medial third of the clavicle. Both lungs are separated from the ipsilateral scalenus anterior muscles by the intervening subclavian artery. As the vessel takes its superior ...

Feb 4, 2025 · Each lung consists of: Apex – The blunt superior end of the lung. It projects upwards, above the level of the 1st rib and into the floor of the neck. Base – The inferior surface of the lung, which sits on the diaphragm. Lobes (two or three) – …

May 4, 2022 · Lung apex is the term used to describe the very top of the lungs. This description can be found on many different types of reports from X-rays to MRI. Lung apex is a tough area to evaluate on x-ray because of all the overlapping structures, like ribs, clavicle and blood vessels.

Apr 20, 2024 · The lung has an apex, base, 3 surfaces, and 3 borders. The apex lies above the 1st rib and is covered by the cervical pleura. The base is the lung's concave inferior surface resting on the diaphragm.

Each lung has a base resting on the diaphragm and an apex extending superiorly to a point approximately 2.5 cm superior to the clavicle. It also has a medial surface and with three borders- anterior, posterior and inferior.

Discover the anatomy and essential functions of the lungs, including their surfaces, borders, impressions, hilum, and roots. Explore the differences between the right and left lungs. Learn about the lobes, fissures, and segments of the lungs.

The apex of the lung is the superior region, whereas the base is the opposite region near the diaphragm. The costal surface of the lung borders the ribs. The mediastinal surface faces the midline.

The apex (apex pulmonis) is rounded, and extends into the root of the neck, reaching from 2.5 to 4 cm. above the level of the sternal end of the first rib. A sulcus produced by the subclavian artery as it curves in front of the pleura runs upward and lateralward immediately below the apex.

apex towards the root of lung. Each segment is an independent respiratory unit. Each segment has its own separate artery(branches of pulmonary artery). Pulmonary Veins run in inter-segmental planes between adjoining segments. Thus a bronchopulmonary segment is not a bronchovascular segment as it does not have its own vein.

The superior end of the lungs narrows to a rounded tip known as the apex. The inferior end of the lungs, known as the base, rests on the dome-shaped diaphragm. The base of the lungs is concave to follow the contour of the diaphragm.
