This is the nerve that provides motor innervation to the intrinsic laryngeal muscles.
What is the recurrent laryngeal nerve?
This genus originally consisted of a large heterogeneous collection of non-fermentative bacteria that were grouped together because of their morphologic similarity.

This is the most common cause of bacterial gastroenteritis in both developed and developing countries, with C. jejuni responsible for most infections and C. coli associated with a minority of cases of Campylobacter gastroenteritis in the United States (more commonly observed in developing countries).
What is Campylobacter?
The tensile strength of collagen requires this enzyme.
