The infrahyoid muscle mass are accountable for the site of the hyoid bone along with the suprahyoid muscles. They play an energetic function in swallowing and the movement of the larynx. More specifically, all infrahyoid muscle groups (except the sternothyroid) depress the hyoid.
The suprahyoid muscles are 4 muscles located above the hyoid bone within the neck. They’re the digastric, stylohyoid, geniohyoid, and mylohyoid muscles. The mylohyoid muscles are thin, flat muscles that shape a sling not so good as the tongue supporting the floor of the mouth.
Beside above, how do I keep in mind my hyoid muscles? Mnemonic
- C: constrictor muscle (middle pharyngeal)
- H: hyoglossus muscle.
- D: digastric muscle (intermediate tendon)
- S: stylohyoid muscle.
- G: geniohyoid muscle.
- M: mylohyoid muscle.
- T: thyrohyoid muscle.
- O: omohyoid muscle.
what is the functional change among Suprahyoid muscle groups and Infrahyoid muscles?
13.11). Both agencies of muscles are worried with melancholy of the mandible and next beginning of the mouth, movement of the tongue, swallowing, and speaking. The infrahyoid muscles stabilize the hyoid bone in order that the suprahyoid muscles have a company base to help with depression of the mandible.
Why does my hyoid bone hurt?

What does the Geniohyoid do?
The geniohyoid muscle is probably the suprahyoid muscle mass of the neck that’s innervated via the ventral ramus of C1. Geniohyoid attracts the hyoid bone up and ahead in the course of mastication and assists the hole of the mandible.
How do you stretch your Digastric muscle?
To passively stretch the posterior stomach of the digastric, the patient leads the pinnacle again against the practitioner in a relaxed location with the teeth almost approximated. For stretching of the right posterior digastric, the patient’s head is became to the right to go the mastoid process away from the hyoid bone.
Which higher neck muscle mass depress the hyoid bone?
The infrahyoid muscle tissue operate to depress the hyoid bone and larynx during swallowing and speech.
What muscle depresses the hyoid bone?
Function. The infrahyoid muscle groups are responsible for the location of the hyoid bone together with the suprahyoid muscles. They play an active role in swallowing and the movement of the larynx. More specifically, all infrahyoid muscle mass (except the sternothyroid) depress the hyoid.
What is the Stylopharyngeus muscle?
The stylopharyngeus is a muscle within the head that stretches between the temporal styloid process and the pharynx.
What does the Suprahyoid muscle do?
The Suprahyoid Muscles. The suprahyoid muscle tissue are a collection of 4 muscles, located superiorly to the hyoid bone of the neck. They all act to raise the hyoid bone – an action fascinated by swallowing. The arterial supply to these muscle mass is by means of branches of the facial artery, occipital artery and lingual artery.
What does the Sternohyoid muscle do?
The sternohyoid muscle’s leading operate is the melancholy of the hyoid bone. The hyoid bone is positioned lower than the mandible, or lower jaw, and is a ‘U’ fashioned bone that is partially responsible for tongue action and the movement of swallowing. The sternohyoid is one in all a pair of muscle tissue liable for this action.
What are the triangles of the neck?
The triangular space in front of this muscle is called the anterior triangle of the neck; and that in the back of it, the posterior triangle of the neck. The anterior triangle is further divided into muscular, carotid, submandibular and submental and the posterior into occipital and subclavian triangles.
Which of right here muscle mass are often referred to as strap muscles?

Where are the strap muscles?
The infrahyoid muscle mass (strap muscles) are a set of four pairs of muscle tissue within the anterior (frontal) portion of the neck. The 4 infrahyoid muscle groups are; the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles. The infrahyoid muscle mass both originate from or insert on to the hyoid bone.
