Monkeys and apes are unable to learn new vocalizations, and for decades it has been widely believed that this inability results from limitations of their vocal anatomy: larynx, tongue and lips. But an ...

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, ...

The recurrent laryngeal nerve (RLN) is critical for speech as it provides nerve function to muscles in the larynx, or voice box. People have two RLNs, one on each side of the neck. Instead of ...

While a sudden coughing fit is a protective reflex to clear the airway, chronic cough can be caused by multiple factors that must be investigated to determine treatment. Cough is just one of several ...

IN a previous communication 1, we suggested that mechanoreceptor nerve endings in the capsules of the laryngeal joints might contribute to the reflex regulation of the activity of the intrinsic ...

The elastic recoil of the lungs provides the necessary acoustic energy, while the diaphragm, intercostal muscles, and abdominal muscles manipulate how that air is released through the larynx, a ...

A recent study said superior laryngeal nerve (SLN) blocks are effective for treating neurogenic cough, which are coughs that continue and persist after other conditions are ruled out. A new study ...
