6. Muscles of the pharynx

The pharyngeal muscles are divided into constrictor muscles (Mm. constrictores pharyngis superior, medius and inferior) and levator muscles (M. stylopharyngeus, M. salpingopharyngeus and M. palatopharyngeus) .

6.1. Pharyngeal constrictor muscles

Rr. pharyngeales of the N. glossopharyngeus [IX] (= Plexus pharyngeus)

O: Pars pterygopharyngea: Lamina medialis of the Proc. pterygoideus, Hamulus ossis pterygoidei

Pars buccopharyngea: Raphe pterygomandibularis

Pars mylopharyngea: Linea mylohyoidea of the Mandibula

Pars glossopharyngea: M. transversus linguae

I: Membrana pharyngobasilaris, Raphe pharyngis

F: participation in swallowing, narrows the pharyngeal space (PASSAVANT's ridge), separates the epipharynx from the mesopharynx

Rr. pharyngeales of the N. glossopharyngeus [IX] and of the N. vagus [X] (= Plexus pharyngeus)

O: Pars chondropharyngea: Cornu minus ossis hyoidei

Pars ceratopharyngea: Cornu majus ossis hyoidei

I: Raphe pharyngis

F: participation in swallowing, narrows the pharyngeal space from behind, promotes wave-like contractions running downwards to support the transport of ingested food into the oesophagus (peristalsis)

Rr. pharyngeales of the N. vagus [X] (= Plexus pharyngeus)

O: Pars thyropharyngea: Cartilago thyroidea

Pars cricopharyngea: lateral side of the Cartilago cricoidea

I: Raphe pharyngis

F: closes the Aditus laryngis by elevating the larynx, narrows the pharyngeal space from behind, promotes wave-like downward contractions to support the transport of ingested food into the oesophagus (peristalsis)

6.2. Pharyngeal levator muscles

Rr. pharyngeales of the N. glossopharyngeus [IX] (= Plexus pharyngeus)

O: Aponeurosis palatina, Hamulus pterygoideus, Lamina medialis processus pterygoidei

I: lateral wall of the pharynx, upper margin of the thyroid cartilage

F: tenses the soft palate; pulls the pharyngeal wall in an anterior, superior and medial direction during swallowing; works together with the muscle on the opposite (contralateral) side

Rr. pharyngeales of the N. glossopharyngeus [IX] (= Plexus pharyngeus)

O: Cartilago tubae auditivae

I: projects into the lateral wall of the pharynx

F: elevates the pharynx, opens the Tuba auditiva; works together with the muscle on the opposite (contralateral) side

R. musculi stylopharyngei of the N. glossopharyngeus [IX]

O: Proc. styloideus of the Os temporale

I: Cartilago thyroidea, projects into the lateral wall of the pharynx

F: elevates the pharynx, pulls the pharyngeal wall upwards above the bolus; its horizontally oriented fibre bundles dilate the Isthmus faucium; works together with the muscle on the opposite (contralateral) side

7. Muscles of the larynx

R. externus of the N. laryngeus superior of the N. vagus [X]

O: Pars interna: ventral surface of the lamina of Cartilago cricoidea

Pars recta and Pars obliqua: ventral surface of the lamina of the Cartilago cricoidea

I: inner surface of the lamina of the Cartilago thyroidea and Conus elasticus

Pars recta: inferior margin of the lamina of the Cartilago thyroidea

Pars obliqua: Cornu inferius of the Cartilago thyroidea

F: tenses (elongates) the vocal ligaments by tilting the cricoid cartilage (strongest tensor muscle of the vocal ligaments → gross tension)
