Results show that The DDR cannot be safely cut free from the ICA adventitia, according to the histologic findings of the study. Instead, the DDR should be cut circumferentially, leaving a 2mm cuff of DDR on the ICA to ensure safe clinoidal segment movement and reduce the risk of arterial damage. -

The distal dural ring or DDR is a protected intracranial anatomic feature that marks the point where the internal carotid artery (ICA) leaves the cavernous sinus (CS) and into the subarachnoid space. Despite the fact that the CS has been well documented in a variety of anatomic investigations, no previous work has looked at the histologic link…[Read more]

Ciliated Pseudostratified Columnar Epithelium In the trachea and bronchi, the epithelium lining it is pseudostratified which largely comprises of three cell types: cilia, goblet, and basal cells. The cilia are found across the apical surface to help mucus move through the respiratory tract.

Simple Squamous Epithelium The small, sacs known as alveoli found throughout the lungs are lined by Simple Squamous Epithelia. Alveolar epithelial cells I (AEC I) occupy around 95% of the alveolar surface area and participate in exchange of gases. Alveoli transport oxygen from the respiratory system to the blood and CO2 from the blood back to the…[Read more]

Elastic Cartilage The epiglottis is an elastic cartilage structure at the base of the tongue that folds over the glottis when swallowing to avoid food or fluids from reaching the trachea. Elastic cartilage is identical to hyaline cartilage, but it has a dense network of branching elastic fibers in its matrix.

Duodenum: The duodenum has three layers, which are similar to all hollow organs of the GIT, but it also has Brunner's glands, which are the duodenum's distinguishing feature. It is the first of the three segments of the small intestine, receiving partly digested food from the stomach and beginning nutrient uptake. It is directly connected to the…[Read more]

Gallbladder: The gallbladder is a muscular sac with a simple columnar epithelium lining it. In humans, it absorbs and contains bile from the liver through the hepatic and then cystic ducts, with a capacity of 50 to 100ml. It is linked to the liver's visceral layer.

Liver: The liver is divided into two lobes: right and left. Hexagonally shaped lobules make up each lobe. These lobules are quite little, each made up of several hepatocytes (liver cells) that are arranged in radiating rows.

Appendix: The appendix has the same structure as the large bowel: serous, muscular, submucous, and mucous. The lamina propria of the appendix contains extensive clumps of lymphoid tissue that protrude into the lumen. These collections are most noticeable in childhood and gradually fade with adulthood. Columnar epithelium lines the appendix mucosa,…[Read more]
