What is the innervation of the geniohyoid?
What is the innervation of the geniohyoid?
Geniohyoid muscle is innervated by the anterior ramus of spinal nerve C1 carried by the hypoglossal nerve.
What Innervates the sternohyoid muscle?
The sternohyoid muscle is an infrahyoid muscle of the neck that is innervated by the ansa cervicalis of the cervical plexus receiving fibers from the ventral rami of C1-C3 spinal nerves.
What Innervates the stylohyoid muscle?
The facial nerve has a significant contribution to the oropharyngeal phase of deglutition through various muscles. It innervates the stylohyoid muscle in association with other muscles, such as the buccinator muscle, perioral muscles, and the posterior belly of the digastric muscle.
What is the action of Genioglossus?
The primary function of the genioglossus muscle is to protrude the tongue anteriorly and deviate the tongue to the opposite side. [5] It also aids in swallowing as it will create a passage to the GIT. [5] When the left and right genioglossus muscles act together, they will depress the middle part of the tongue.
What is the Thyrohyoid innervated by?
hypoglossal nerve
Innervation. The thyrohyoid muscles are innervated by a branch of the ventral ramus of C1 from the cervical plexus, which courses with the hypoglossal nerve. The nerve fibers are thus not from the hypoglossal nucleus.
What are sternohyoid muscles?
As for the sternohyoid muscle, it is a flat muscle located on both sides of the neck. This muscle originated from the medial edge of the clavicle bone, sternoclavicular ligament, and posterior side of the manubrium. The sternohyoid muscle then ascends the neck and attaches to the body of the hyoid bone.
What is the action of the sternohyoid?
The sternohyoid muscle is a thin, narrow muscle attaching the hyoid bone to the sternum. It is one of the paired strap muscles of the infrahyoid muscles. It is supplied by the ansa cervicalis….

What branch of facial nerve Innervates stylohyoid?
Stylohyoid receives innervation from the stylohyoid branch of the facial nerve (Cranial nerve 7). The branch arises right after the facial nerve passes the mastoid process of temporal bone to enter the middle part of the muscle.
What Innervates the digastric muscle?
The mylohyoid nerve of the inferior alveolar nerve of the mandibular nerve of the trigeminal nerve innervates the anterior belly of the digastric muscle, and the facial nerve innervates the posterior belly of the digastric muscle [10].
Is the genioglossus muscle bilaterally innervated?
The genioglossus muscle is innervated by the cranial nerve XII, which is also known as the hypoglossal nerve. This muscle receives its blood supply from both the lingual artery and facial artery.
