| digestive tube | The passage leading from the mouth to the anus through the pharynx, oesophagus, stomach, and intestine. Synonym: alimentary canal, alimentary tract, digestive tube, tubus digestorius. (05 Mar 2000) |

| digestive vacuole | Intracellular vacuole into which lysosomal enzymes are discharged and digestion of the contents occurs. More commonly referred to as a secondary lysosome. (18 Nov 1997) |
| endoscopy, digestive system | Visual examination of the digestive tract by means of a fibreoptic endoscope. It is used to localise, identify, and photograph pathologic alterations, to obtain biopsy material and perform other surgical interventions, and for delivery of medication. (12 Dec 1998) |
| annulospiral organ | One of two types of sensory nerve ending associated with a neuromuscular spindle (the other being the flower-spray ending); after entering the muscle spindle, the fibre divides into two flat ribbon-like branches that wind themselves in rings or spirals about the intrafusal muscle fibres. Synonym: annulospiral organ. (05 Mar 2000) |

| bojanus organ | <zoology> A glandular organ of bivalve mollusca, serving in part as a kidney. Origin: From Bojanus, the discoverer. Source: Websters Dictionary (01 Mar 1998) |
| vestibular organ | Collective term for the utricle, saccule, and saemicircular ducts of the membranous labyrinth, each having a single patch of ciliated receptor epithelium innervated by the vestibular nerve: macula of sacculus, macula of utriculus, and cristae of the saemicircular ducts.

| visual organ | The eye and its adnexa. Synonym: organum visus, organ of vision. (05 Mar 2000) |
| vomeronasal organ | A specialised part of the olfactory system located anteriorly in the nasal cavity within the nasal septum. Chemosensitive cells of the vomeronasal organ project via the vomeronasal nerve to the accessory olfactory bulb. The primary function of this organ appears to be in sensing pheromones which regulate reproductive and other social behaviours. While the structure has been thought absent in higher primate adults, data now suggests it may be present in adult humans. (12 Dec 1998) |
| Golgi tendon organ | <cell biology, physiology> A proprioceptive sensory nerve ending embedded among the fibres of a tendon, often near the musculotendinous junction; it is compressed and activated by any increase of the tendon's tension, caused either by active contraction or passive stretch of the corresponding muscle. Synonym: neurotendinous organ, neurotendinous spindle. (05 Mar 2000) |
| Chievitz' organ | A normal epithelial structure, possibly a neurotransmitter, found at the angle of the mandible with branches of the buccal nerve. (05 Mar 2000) |
| gustatory organ | Located in the papillae of the mucous membrane of the tongue, chiefly in the vallate papillae. Synonym: organum gustus, organ of taste. (05 Mar 2000) |
