| alar lamina of neural tube | The dorsal division of the lateral walls of the neural tube in the embryo; it gives rise to neurons relaying afferent impulses to higher centres; in the adult such neurons compose the sensory nuclei of the spinal cord and brainstem. Synonym: lamina alaris, alar plate of neural tube, dorsolateral plate of neural tube, lamina dorsalis, wing plate. (05 Mar 2000) |

| ampulla of uterine tube | The wide portion of the uterine (fallopian) tube near the fimbriated extremity; it has a complexly folded mucosa with a columnar epithelium of mostly ciliated cells between which are secretory cells. Synonym: ampulla tubae uterinae. (05 Mar 2000) |
| ampullary folds of uterine tube | One of the folds of mucous membrane at the fimbriated extremity of the uterine tube. Synonym: plicae ampullares tubae uterinae. (05 Mar 2000) |
| auditory tube | A tube leading from the tympanic cavity to the nasopharynx; it consists of an osseous (posterolateral) portion at the tympanic end, and a fibrocartilaginous (anteromedial) portion at the pharyngeal end; where the two portions join, in the region of the sphenopetrosal fissure, is the narrowest portion of the tube (isthmus); the auditory tube enables equalization of pressure within the tympanic cavity with ambient air pressure, referred to commonly as "popping of the ears". Synonym: tuba auditiva, tuba auditoria, eustachian tube, guttural duct, otopharyngeal tube, otosalpinx, pharyngotympanic tube, salpinx, tuba acustica, tuba eustachiana, tuba eustachii.

| bony part of auditory tube | The portion of the auditory tube that passes from the tympanic cavity anteromedially through the saemicanal for auditory tube. Synonym: pars ossea tubae auditivae. (05 Mar 2000) |
