     part:  #descending_colon  the part of the large intestine that descends from the transverse colon to the sigmoid colon
     part:  #sigmoid_colon__sigmoidcolon__sigmoid_flexure__sigmoidflexure  the s-shaped curve between the descending colon and the rectum
     part:  #rectum  the terminal section of the alimentary canal; from the sigmoid flexure to the anus
        part:  #rectal_artery__arteria_rectalis  one of the arteries supplying the rectal area
        part:  #anus__arse__arsehole__asshole  excretory opening at the end of the alimentary canal

              part:  #musculus_sphincter_ani_externus  an external ring of striated muscle surrounding the anus
              part:  #musculus_sphincter_ani_internus  an internal ring of smooth muscle formed by circular fibers of the rectum
  part:  #pharynx__throat  the passage to the stomach and lungs; in the front part of the neck below the chin and above the collarbone
     part:  #lingua__tongue__glossa__clapper  a mobile mass of muscular tissue covered with mucous membrane and located in the oral cavity
        part:  #tastebud__taste_bud__tastebud__gustatory_organ__gustatoryorgan  an oval sensory end organ on the surface of the tongue
           part:  #neuroepithelium  epithelium associated with special sense organs and containing sensory nerve endings
           part:  #taste_cell__tastecell__gustatory_cell__gustatorycell  an epithelial cell in a taste bud that activates sensory fibers of the facial nerve or the glossopharyngeal nerve or the vagus nerve
     part:  #nasopharynx  cavity forming the upper part of the pharynx
        part:  #palatine_tonsil__tonsil__faucial_tonsil__faucialtonsil__tonsilla  either of two masses of lymphatic tissue one on each side of the oral pharynx
