Mylohyoid nerve
Encyclopedia
The mylohyoid nerve is a nerve that innervates the mylohyoid muscle
and the anterior belly of the digastric muscle
.
(a branch of the mandibular nerve
, the third part of the trigeminal nerve
) just before it enters the mandibular foramen
.
It descends in a groove on the deep surface of the ramus of the mandible, and reaching the under surface of the mylohyoid muscle
, it supplies both the mylohyoid and the anterior belly of the digastric muscle
.
Mylohyoid muscle
The mylohyoid muscle is a muscle running from the mandible to the hyoid bone, forming the floor of the oral cavity. It is named for its two attachments, with the prefix "mylo" coming from the Greek word for "molar". These muscles are mesodermal in origin...

Digastric muscle
The digastric muscle is a small muscle located under the jaw. so digastric muscles are muscle fibers in ligament of treitz ,omohyoid , occipitofrontalis....

Trigeminal nerve
The trigeminal nerve contains both sensory and motor fibres. It is responsible for sensation in the face and certain motor functions such as biting, chewing, and swallowing. Sensory information from the face and body is processed by parallel pathways in the central nervous system...
