Pharyngis medius constrictor muscle
origin
Pars chondropharyngea (Musculi constrictoris pharyngis medii):
- Cornu minus ossis hyoidei

Pars ceratopharyngea (Musculi constrictoris pharyngis medii):
- Cornu majus ossis hyoidei

approach
Raphe pharyngis
function
Constriction of the pars oralis pharyngis:

pushes the chunk of food towards the esophagus during the act of swallowing

Innervation
Pharyngeal plexus :

Glossopharyngeal nerve (cranial nerve IX)
vagus nerve (cranial nerve X)

The musculus constrictor pharyngis medius (from Latin musculus "muscle", constringere "to contract", from Greek phárynx "throat" and Latin medius "located in the middle"), in German mean throat cord , is a fan-shaped, striated muscle ( skeletal muscle ), which, together with the musculi constrictores pharyngis superior et inferior , forms the muscular part of the throat . It is particularly prominent in its dorsal and lateral areas. On the dorsal wall of the pharynx, the paired muscle parts are connected to each other by the pharyngeal raphe , which also serves as an attachment for the throat constricters.

The muscle can be further divided into one:

  • Pars chondropharyngea musculi constrictoris pharyngis medii
  • Pars ceratopharyngea musculi constrictoris pharyngis medii

function

The musculus constrictor pharyngis medius constricts the pars oralis pharyngis and pushes the chunk of food towards the esophagus during the act of swallowing .
