Medically reviewed by Lauren Schlanger, MD The recurrent laryngeal nerve (RLN) anatomy is designed to supply function to most muscles of the larynx (voice box). It branches from the vagus nerve ...

Evolutionary simplification in the human larynx – the loss of vocal membranes and air sacs common to all nonhuman primates – enabled the increased acoustic complexity required by human speech ...

By using ultra-high-speed photography at approximately 5,000 frames per second, the film reveals the intricate and rapid movements of the larynx in slow motion.

The researchers studied laryngeal anatomy in apes including chimpanzees, gorillas, orangutans and gibbons, as well as Old World monkeys including macaques, guenons, baboons and mandrills and New ...

A paper argues that the evolutionary loss of a thin vocal membrane in the larynx may have facilitated oral communication.

Why are humans the only primates that can speak? Spoken language may have been made possible by simplification of the laryngeal anatomy, including the loss of vocal membranes and air sacs that are ...
