supratonsillar

The lymphoid mass, however, does not completely fill the interval between the two arches, so that a small depression, the supratonsillar fossa, exists at the upper part of the interval.

Further, the tonsil extends for a variable distance under cover of the glossopalatine arch, and is here covered by a reduplication of mucous membrane; the upper part of this fold reaches across the supratonsillar fossa, between the two arches, as a thin fold sometimes termed the plica semilunaris; the remainder of the fold is called the plica triangularis.

Between the two arches of either side is the palatine tonsil, above which is the small supratonsillar recess; the position of the tonsil corresponds to the angle of the mandible.

The inner part of the second pharyngeal pouch is named the sinus tonsillaris; in it the tonsil is developed, above which a trace of the sinus persists as the supratonsillar fossa.
