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 between the ICA and DDR. The goal of this research was to analyze the DDR’s connection to the ICA and establish whether it can be dissected from the ICA and therefore partitioned, or if it can simply be circumferentially cut around the artery.
The specimen used were from 10 cadavers that were fresh-frozen. The procedure included a typical frontotemporal craniotomy, orbito-optic osteotomy, and bilateral extradural anterior clinoidectomy. The collected specimens were the cavernous ICA, DDR, as well as the supraclinoid ICA. These specimens were fixed with formalin and embedded in paraffin and stained with hematoxylin and eosin, and Masson trichome.
Histology of the distal dural ring – PubMedThe distal dural ring (DDR) is a conserved intracranial anatomic structure marking the boundary point at which the internal carotid artery (ICA) exits the cavernous sinus (CS) and enters the subarachnoid space. Although the CS has been well described in a range of anatomic studies, to our knowledge …
Histology Art on Muscle Tissues
Muscle tissues are made up of cells with a unique capacity to contract in order to set bodily components in motion. The tissue is densely packed with cells and has an abundant supply of blood vessels. Because the cells are long and thin, they are sometimes referred to as muscle fibers and are typically grouped in bundles or layers, surrounded by connective tissue.

Other tissues and organs in the body are supported, protected, and given structure by connective tissue.
The major function of osseous tissue is to generate bones enabling the body to move by allowing muscles and tendons to connect to them.
Adipose tissue, or fat tissue, is made up primarily of fat cells (adipocytes). Adipocytes are fat-storing cells with big globules of fat called lipid droplets which are supported by a network of fibers.
The only liquid tissue that our body has is blood. It is approximately 5 liters, accounting for 8% of an adult’s weight. It is made up of cells and formed components floating in its intercellular matrix, the plasma.
