1. The sublingual structures of primates have been studied light-microscopically. There are 3 different sublingual structures in the species studied. The plica sublingualis occurs in all primates. The sublingual organ is a topographically modified plica sublingualis which occurs exclusively in Callicebus. A sublingua is present only in the prosimians. 2. The plica sublingualis contains the excretory ducts of the submandibular and sublingual salivary glands. The sublingua is ventrally adherent to the body of the tongue and is, with a few exceptions in Tupaia, characterized by a skeleton of cartilage tissue. A sublingua never exhibits excretory ducts or salivary glands. 3. In some Platyrrhini (Ateles, Aotus, Lagothrix, Alouatta, Callicebus), there are taste buds in the epithelium of the plica sublingualis. They are especially concentrated near the orifices of the salivary glands. 4. The fresh saliva of the submandibular and sublingual gland can be tested by the taste buds on the plica sublingualis, because there is a topographical coincidence. 5. There is a complete absence of taste buds at the plica sublingualis of the prosimians and the Cercopithecinae. 6. There are no taste buds in the epithelium of the sublingua. In the Loris...Continue Reading

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.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
