What does the Stylohyoid muscle do?
The stylohyoid muscle connects the hyoid bone to the base of the mandible and the skull. It pulls the hyoid bone upward and backward, resulting in elevation of the base of the tongue and elongation of the floor of the mouth. This movement helps in deglutition.
What is the action of stylohyoid?
The stylohyoid muscle extends between the temporal and hyoid bones….Stylohyoid muscle.
| Origins | Styloid process of temporal bone |
|---|---|
| Action | Elevates and draws hyoid bone posteriorly |
| Innervation | Stylohyoid branch of facial nerve (CN VII) |
What is the function of the stylohyoid ligament?
Structure. The stylohyoid ligament connects the lesser horn of hyoid bone to the styloid process of the temporal bone of the skull.
Why is it called stylohyoid?
It is one of the suprahyoid muscles. It shares this muscle’s innervation by the facial nerve, and functions to draw the hyoid bone backwards and elevate the tongue. Its origin is the styloid process of the temporal bone. It inserts on the body of the hyoid….Stylohyoid muscle.

What does the Hyoglossus muscle do?
These muscles attach to the superior aspect of the hyoid bone, and their main combined function is to elevate the hyoid and larynx and move them superiorly and anteriorly. The thyrohyoid, sternohyoid, sternothyroid, and omohyoid muscles, also referred to as strap muscles, are part of the infrahyoid musculature.
Where is the genioglossus muscle?
tongue
The genioglossus muscle is a fan-shaped muscle that is involved in forming most of the tongue mass. It emerges from the superior mental spines and inserts on the hyoid bone as well as the inferior portion of the tongue.
What is the Styloglossus muscle?
The styloglossus muscle is an extrinsic muscle of the tongue, and its origin in the styloid process of the temporal bone is well documented. However, some authors have noted variations in its origin.
Can styloid process be cured?
Surgery to shorten the styloid process is the primary treatment for Eagle syndrome. This procedure, called a styloidectomy, can be done through the mouth or neck. Surgery through the mouth requires removal of the tonsils , and it can be more difficult for the surgeon to access the styloid process.
What happens when the hyoglossus contracts?
(2) They contract against blows to form a rigid protective wall for the viscera. (3) When the glottis is closed and the thorax and pelvis are fixed, these muscles take part in the expulsive efforts of urination, defecation, childbirth, vomiting, and of singing and coughing.
What does the genioglossus do?
The primary function of the genioglossus muscle is to protrude the tongue anteriorly and deviate the tongue to the opposite side.
Does the genioglossus move the mandible?
Contraction of the genioglossus stabilizes and enlarges the portion of the upper airway that is most vulnerable to collapse. Given this connection, the mandible can be pulled forward to maximise the airway space, and prevent the tongue from sinking backwards under anaesthesia and obstructing the airway.
What is the stylohyoid muscle?
The muscle starts at the styloid process, a pointed part of the skull’s temporal bone, which lies just below the ear and functions as an anchor point for a number of muscles. The stylohyoid is located just in front of the digastric muscle, which lifts the tongue back when swallowing.
Why is the stylohyoid important to the process of eating?
It is essential to the process of eating. The muscle starts at the styloid process, a pointed part of the skull’s temporal bone, which lies just below the ear and functions as an anchor point for a number of muscles. The stylohyoid is located just in front of the digastric muscle, which lifts the tongue back when swallowing.
What is elongation of the stylohyoid process?
Elongation of the stylohyoid process is thought to be associated with Eagle syndrome. It is frequently considered as an incidental finding which may or may not be reported in routine radiology practice.
Is there a cure for stylohyoid?
Stylohyoid. One notable one is myofascial pain syndrome, which causes severe pain in these muscles. There is no known cure to this syndrome, although nonsteroidal anti-inflammatory drugs, such as aspirin and ibuprofen, are prescribed to reduce pain and inflammation. In very severe cases, injections are used to numb the affected area.
