The '''Digastricus muscle''' is the 'jaw closing' muscle. Its origin is the '''paracondylar process''' of the '''[[Skull and Facial Muscles - Anatomy & Physiology#Occipital Bone (os occipitale)|occipital bone]]'''. It inserts at the angle of the '''[[Skull and Facial Muscles - Anatomy & Physiology#Mandible (mandibula)|mandible]]'''. The muscle has two bellies; The '''caudal half''' from the second visceral arch innervated by the '''facial''' nerve ([[Cranial Nerves - Anatomy & Physiology|CN VII]]) and the '''cranial half''' from the first visceral arch, innervated by the '''mandibular''' branch of the '''trigeminal''' nerve ([[Cranial Nerves - Anatomy & Physiology|CN V3]]).
