About the mylohyoid muscle of the dog
Mylohyoid muscle is a muscle of the head (head), one on each side of the body. Its name in the Nomina Anatomica Veterinaria is Musculus mylohyoideus. You can turn it above, see it in place in the head of the dog, and open it inside the whole animal in Vetomica.
Where it runs from and to
A muscle is told apart from its neighbours by what it takes hold of at each end, which is also what decides what it does when it shortens.
- Origin
- Medial surface of each half of the mandible, along the line below the teeth.
- Insertion
- A median raphe between the two halves of the jaw, and the basihyoid bone.
- Action
- Forms a sling under the tongue and raises the floor of the mouth.
- Nerve
