hyolarynx muscles Flashcards
anterior belly of digastric
elevates hyoid during swallowing, innervated by CN V- Trigeminal suprahyoid
mylohyoid
elevates hyoid during swallowing, innervated by CN V- Trigeminal, suprahyoid
geniohyoid
elevates hyoid during swallowing, initiates hyolaryngeal movement, innervated by CN XII- hypoglossal and Spinal nerve C1
hyoglossus
approximates hyoid and tongue during swallowing, innervated by CN XII- hypoglossal, suprahyoid muscle
posterior belly of the diagastrics
elevates hyoid during swallowing, courses- hyoid bone to mastoid process, innervated by CN VII- Facial, suprahyoid
stylohyoid
elevated hyoid during swallowing, courses hyoid and styloid process, CN VII - Facial, suprahyoid
stylopharyngeus
elevates larynx during swallow, courses larynx to styloid process, innervated by CN IX- glossopharyngeal, suprahyoid and 1/3 longitudinal pharyngeal muscle
longitudinal pharyngeal muscles
stylopharyngeus
palatopharyngeus
salpingopharyngeus
palatopharyngeus
indirectly elevates the larynx during swallowing, connected for the soft palate to the stylopharyngeus which connects it to the larynx, innervated by the Pharyngeal Plexus (CN IX and X), suprahyoid and longitudinal pharyngeal muscle
salpingopharyngeus
elevates larynx during swallowing, connects larynx and auditory tube, innervated by the Pharyngeal Plexus(CN IX and X), suprahyoid and longitudinal pharyngeal muscle
thyrohyoid
elevates larynx during swallowing, connects hyoid and larynx, innervated by Cervical Plexus (C1), infrahyoid
strenohyoid
depresses hyoid, courses hyoid and sternum, innervated by Cervical Plexus (C1-3 spinal nerves), infrahyoid
omohyoid
depresses hyoid, courses hyoid to clavicle, innervated by Cervical Plexus (C1-3 spinal nerves), infrahyoid
sternothyroid
depresses larynx, courses larynx to sternum, innervated by Cervical Plexus(C1-3), infrahyoid
