The stylohyoid is a suprahyoid muscle of the neck. It consists of a thin muscular strip, which is located superior to the posterior belly of the digastric muscle. 

  • Attachments: Arises from the styloid process of the temporal bone and attaches to the lateral aspect of the hyoid bone.
  • Actions: Initiates a swallowing action by pulling the hyoid bone in a posterior and superior direction.
  • Innervation: Stylohyoid branch of the facial nerve (CN VII) (arises proximal to the parotid gland).
  • Blood Supply: Branches of the facial, occipital and posterior auricular arteries
