Correct Answer
digrastic, trigeminal V/facial VII

Explanation
The digastric muscle elevates the hyoid bone and assists in depressing the mandible. It is innervated by both the trigeminal nerve (V) and the facial nerve (VII).

Muscle and Nerve Innervation of the LarynxResponsible for stabilizing the hyoid bone and innervated by the hypoglossal XII:
- A.
  
  Sternohyoid, Stylohyoid, Thyrohyoid, Omohyoid
- B.
  
  Stylohyoid, Omohyoid, Mylohyoid, Stylothyroid
- C.
  
  Sternohyoid, Sternothyoid,Thyrohyoid, Omohyoid
- D.
  
  Sternohyoid, Stylothyoid, Sternothyroid, Thyrohoid
- E.
  
  Omohyoid, Sternothyroid, ,Stylothyroid, mylohyoid
Correct Answer
C. Sternohyoid, Sternothyoid,Thyrohyoid, Omohyoid

Explanation
The muscles responsible for stabilizing the hyoid bone and innervated by the hypoglossal XII are the Sternohyoid, Sternothyroid, Thyrohyoid, and Omohyoid muscles. These muscles help to support and position the hyoid bone, which is important for swallowing and speech production. The hypoglossal nerve (cranial nerve XII) provides motor innervation to these muscles, allowing them to contract and perform their functions.
