Abstract

The origin, course and distribution of the nerves to the levator scapulae, rhomboideus, serratus anterior, supraspinatus, infraspinatus, subscapularis, teres minor, deltoid, teres major and latissimus dorsi muscles were examined in 7 kangaroo body-halves. The levator scapulae and the serratus anterior formed a continuous muscle sheet arising from the transverse processes of the lower 5 cervical vertebrae and the upper 6 ribs. The rhomboideus arose from the occipital bone in addition to the cervical dorsal median raphe. Six segmental nerves from C3 to C8 innervated these 3 muscles. Each segmental nerve originated from the dorsal surface of the corresponding root of the cervicobrachial plexus. All these nerves innervated the levator-serratus muscle sheet and 4 segmental nerves from C3 to C6 innervated the rhomboideus. Of the remaining scapular muscles, the supraspinatus was well developed, and the teres minor was a small muscle. The nerves supplying the scapular muscles originated from the area between the upper trunk and the posterior cord of the brachial plexus. Four segmental nerves from C5 to C8 usually innervated these 7 muscles. Judging from the relationships between nerves and muscles, all of these muscles are thought to h...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.
