| electric organ | In about 250 species of electric fishes, modified muscle fibres forming disklike multinucleate plates arranged in stacks like batteries in series and embedded in a gelatinous matrix. A large torpedo ray may have half a million plates. Muscles in different parts of the body may be modified, i.e., the trunk and tail in the electric eel, the hyobranchial apparatus in the electric ray, and extrinsic eye muscles in the stargazers. Powerful electric organs emit pulses in brief bursts several times a second. They serve to stun prey and ward off predators. A large torpedo ray can produce of shock of more than 200 volts, capable of stunning a human. (storer et al., general zoology, 6th ed, p672) (12 Dec 1998) |
| enamel organ | Epithelial cells surrounding the dental papilla and differentiated into three layers: the inner enamel epithelium, consisting of ameloblasts which eventually form the enamel, and the enamel pulp and external enamel epithelium, both of which atrophy and disappear before and upon eruption of the tooth, respectively. (12 Dec 1998) |
| end organ | The special structure containing the terminal of a nerve fibre in peripheral tissue such as muscle, tissue, skin, mucous membrane, or glands. See: ending. (05 Mar 2000) |
| Jacobson's 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) |
| floating organ | An organ with loose attachments, permitting its displacement. Synonym: floating organ, ptotic organ. (05 Mar 2000) |
| flower-spray organ of Ruffini | One of the two types of sensory nerve ending associated with the neuromuscular spindle (the other being the annulospiral ending); in this type, the fibre branches spread out upon the surface of the intrafusal fibres like a spray of flowers. Synonym: flower-spray organ of Ruffini. (05 Mar 2000) |
| foetal organ maturity | <embryology> Functional competence of specific foetal organs or body systems. In humans, it is usually assessed by analysis of amniotic fluid, as in the assessment of foetal lung maturity by analysis for components of pulmonary surfactant. (08 Mar 2000) |
| alveolonasal line | A line connecting the alveolar point and the nasion. (05 Mar 2000) |
| anocutaneous line | The line between the simple columnar epithelium of the rectum and the stratified epithelium of the anal canal. Synonym: linea anocutanea, anocutaneous line, dentate line. (05 Mar 2000) |
| anterior axillary line | A vertical line extending inferiorly from the anterior axillary fold. Synonym: linea axillaris anterior, linea preaxillaris, preaxillary line. (05 Mar 2000) |
| anterior junction line | Radiographic projection of the mediastinal tissue septum between the upper lobes behind the sternum. (05 Mar 2000) |
| anterior median line | The line of intersection of the midsagittal plane with the anterior surface of the body. Synonym: linea mediana anterior. (05 Mar 2000) |
| arcuate line | An arching or bow-shaped line. See: arcuate line of ilium, arcuate line of rectus sheath. Synonym: linea arcuata. (05 Mar 2000) |
| arcuate line of ilium | The iliac portion of the linea terminalis of the bony pelvis. Synonym: linea arcuata ossis ilii. (05 Mar 2000) |
