Histologic Investigation of the Salpingopharyngeus.

Skeletal muscle fibers and/or dense connective tissue can be consistently identified in the section of the salpingopharyngeal fold near the TT. Glandular material is also consistently present in this same region of the salpingopharyngeal fold. These findings are discussed in relation to possible functional roles of the salpingopharyngeal fold contents, including the SP muscle.
