How Mice Squeak: Acoustic Signals of Rodents
The murine larynx is a compact cartilaginous tube positioned just caudal to the trachea, housing the vocal folds that generate ultrasonic vocalizations. The vocal folds consist of a thin layer of extracellular matrix, primarily collagen and elastin, overlying a muscular core that adjusts tension rapidly.. Date latest changes:
Diseases transmissible from mice: risks and prevention
Zoonotic transmission refers to the passage of pathogens from animals to humans. In the case of rodents, the close association between mice and human habitats creates multiple pathways for infectious agents to cross species barriers.
