The subcutaneous vascular system (lower extremity): studies on micro-preparations

Abstract

At the level of fascial penetration the cutaneous arteries of the lower extremity are constantly accompanied by 1 or 2 communicating veins of varying diameter. Usually, they penetrate the fascia in rows via the muscular interstitium. There they give up branches to the fascial vascular network, to pre- and subfascial areolar tissue and possibly to the muscle origins on the fascia, or to the intermuscular septa. The texture of the fascia itself determines the structure of fascial openings for the cutaneous vessels. In the subcutaneous tissue the arteries are accompanied by 1 or 2 veins (Vv. comitantes). Numerous arterio-arterial and intervenous anastomoses form a subcutaneous network of vascular bundles. Two anastomosing venous systems can be distinguished in the subcutis: The small Vv. comitantes are fed primarily by the subcutaneous adipose lobes, and end in communicating veins or flow into the subcutaneous veins (epifascial veins). These large subcutaneous veins on the other hand are responsible for the actual outflow from the venous network of the cutis. They form the saphenous system or empty into larger communicating veins. Between the subcutaneous arterioles and accompanying venules there are numerous capillary webs. In ad...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
