Digastric branch of facial nerve

Nerve: Digastric branch of facial nerve

Plan of the facial and intermediate nerves and their communication with other nerves. ("To digastric" labeled at bottom left.)
Latin	ramus digastricus nervi facialis
Gray's	subject #202 905

The digastric branch of facial nerve arises close to the stylomastoid foramen, and divides into several filaments, which supply the posterior belly of the Digastricus; one of these filaments joins the glossopharyngeal nerve.
