  Neck muscles
The deltoid muscle moves the humerus bone and is used to raise the arm outward from the side.
The muscles run upward and come together in the middle of their course (both pieces of the muscle lie side by side), but do not actually touch and are inserted in the front of the hyoid bone.
The rectus capitis muscles are small triangular muscles that extend from the cervical vertebrae and insert in the occipital bone at the base of the skull.

Geniohyoid is a muscle that spans from the mental spines of the mandible to the body of the hyoid bone--it elevates the hyoid and depresses the mandible.
Hyoglossus is a tongue muscle; it is innervated by the hypoglossal nerve (CN XII).

shift this innervation of the mylohyoid muscle to the neurons in the intermediate part of the nucleus in the rabbit.
The left mylohoid muscle of twenty adult Wistar albino rats was injected slowly at three different places by means of Hamilton syringe mounted on a micro-drive machine, with 10-50µl of DAPI-Pr (25% of 4’6-Diamidino-2-phenyl indole-2-HCL added to equal amounts of 5% Primuline), after resection of the anterior belly of the digastric muscle under anesthesia.
The spreading of the injected dye did not affect the underlying anterior belly of the digastric muscle because that muscle was resected, and no cells were found labeled in the caudal part of the nucleus (the domain area of the digastric muscle).
