| neuromast organ | A structure in fish consisting of a long groove or canal extending along each side of the trunk and tail and branching in the head region; the groove or tube is lined with neuroepithelial cells, some of which are in groups known as neuromasts; its function appears to be the detection of vibrations of low frequency. Synonym: neuromast organ. (05 Mar 2000) |
| neurotendinous 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) |

| intromittent organ | <anatomy> The male organ of copulation and of urinary excretion, comprising a root, body and extremity or glans penis. The root is attached to the descending portions of the pubic bone by the crura, the latter being the extremities of the corpora cavernosa and beneath them the corpus spongiosum, through which the urethra passes. The glans is covered with mucous membrane and ensheathed by the prepuce or foreskin. The penis is homologous with the clitoris in the female. (18 Nov 1997) |
| olfactory organ | The olfactory region in the superior portion of the nasal cavity. Synonym: organum olfactus, organ of smell. (05 Mar 2000) |
