Comparative morphology of the lateral meniscus of the knee in primates

Abstract

The morphology of the lateral meniscus has been studied in a series of 316 non-human primates, representative of 43 genera. The lateral meniscus has a crescentic shape in Prosimii, in Platyrrhinii (New World monkeys) and in Pongo pygmaeus. The lateral meniscus is disc-shaped, with a central foramen, in Catarrhinii (Old World monkeys), in Hylobates, in Gorilla and in Pan Troglodytes. In man, the lateral meniscus has a crescentic shape. Discoid lateral menisci are reported as anomalies in man; their origin has given rise to much discussion, but the comparative data favour a phylogenetic origin. The posterior fasciculus (Wrisberg's ligament) of the posterior menisco-femoral ligament is always present and large in all non-human primates; in man, it may be absent and seems to be a regressive structure. On the other hand, the anterior fasciculus (Humphry's ligament) exists only in man and seems to be a progressive structure. The posterior menisco-tibial attachments are weak or non-existent in non-human primates, but they are well-developed in man. The evolutionary development of these characters can be related to human bipedal locomotion. The lateral meniscus in some Prosimii contains one or two intramensical ossicles (lunulae).

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.
