Description

Origin: Hyoid bone

Insertion: Pharyngeal raphe

Nerve: Vagus nerve

Action: Swallowing

Description:
The Middle constrictor (Constrictor pharyngis medius) is a fanshaped muscle, smaller than the preceding. It arises from the whole length of the upper border of the greater cornu of the hyoid bone, from the lesser cornu, and from the stylohyoid ligament. The fibers diverge from their origin: the lower ones descend beneath the Constrictor inferior, the middle fibers pass transversely, and the upper fibers ascend and overlap the Constrictor superior. It is inserted into the posterior median fibrous raphé, blending in the middle line with the muscle of the opposite side.
