Lung 1 The human left lung is divided into two lobes, an upper and a lower, by the oblique fissure. It has a cardiac notch, a concave impression molded to accommodate the shape of the heart.  The lingula is not technically a lobe, but is the left lung equivalent of the right lung’s middle lobe.

ASSESSMENT OF THE LUNGS AND THORAX THE LUNGS AND THORAX. The lungs are the cone-shaped organs located in the pleural spaces in the right and left sides of the bony thorax. The right lung is divided into three separate and distinct lobes by deep fissures. The left lung has only two lobes. The purpose of the lungs is most importantly the exchange of gases in the body.

Lungs NUMBER: Two. SHAPE: Soft, spongy and coned shaped (see Lungs Title Page) SIZE: The right lung has three lobes and is larger, wider and shorter than the left. The left lung is smaller, narrower and longer with 2 lobes. The average lung capacity is 750 ml or 1 quart. LOCATION: Enclosed by the diaphragm (upper chest) and thoracic cage (ribs) and are separated by the heart, heart vessels, thymus, trachea and esophagus.

oblique fissure Medical Definition of oblique fissure. : either of two fissures of the lungs of which the one on the left side of the body separates the superior lobe of the left lung from the inferior lobe and the one on the right separates the superior and middle lobes of the right lung from the inferior lobe.

- The left mainstem bronchus is about 5 cm in length. Mainstem bronchi divide into the lobar bronchi (secondary) and subsequently into the segmental (tertiary) bronchi (see the image below). Arteries, veins, and lymphatics also enter the lungs at the hilum along with the bronchi.

Lateral View of the Brain Sulci are small grooves, but there are also large grooves, and these are called fissures. Fissures divide the cerebral cortex into lobes and also divide the cerebrum into the right and left cerebral hemispheres along the saggital plane.

Lungs Each lung receives air from a single, large primary bronchus. As the primary bronchi enter the lungs, they branch off into smaller secondary bronchi that carry air to each lobe of the lung. Thus, the right bronchus branches off into 3 secondary bronchi while the left lung branches off into 2 secondary bronchi.

Radiographic and CT Appearances of the Major Fissures The major fissures as well as the minor fissures are often incomplete, and the lung parenchyma of the adjacent pulmonary lobes fuse. Studies differ as to how often the fissure is incomplete (Table) (3,7,18–21). When part of the fissure is absent, it is always toward the mediastinal side of the fissure. The major fissures are usually incomplete near the hilar area and in the upper parts.

Fissure 1 Clevenger's fissure: found in the inferior temporal lobe of the brain. 2  Collateral fissure: found in the inferior surface of the cerebrum. 3  Hippocampal sulcus: a sulcus that extends from the brain's corpus callosum to the tip of the temporal lobe. Fissure of Bichat: found below the corpus callosum in the cerebellum of the brain. 2  Broca's fissure: found in the third left frontal fold of the brain. 3  Burdach's fissure: connects the brain's insula and the inner surface of the operculum.

- The windpipe (trachea) divides into 2 airways, called the right main bronchus and the left main bronchus. One goes to each lung. Within the lungs, they divide into smaller tubes called the secondary bronchi. There are 2 of these on the left side and 3 on the right.
