| fixation, ocular | The direction of the gaze so that the visual image of the object falls on the fovea centralis of the retina, the area of the most acute vision. (12 Dec 1998) |
| Frenkel's anterior ocular traumatic syndrome | <syndrome> An obsolete term for traumatic iridoplegia, which consists of mydriasis, hyphema, small iris tears near the pupil, discrete punctate opacities of the lens, and occasionally iridodialysis. (05 Mar 2000) |

| autonomic motor neurons | (preganglionic neuron's), by contrast, innervate smooth muscle fibres or glands only by the intermediary of a second, peripheral, neuron (postganglionic or ganglionic m. Neuron) located in an autonomic ganglion. See: motor endplate, autonomic nervous system. Synonym: anterior horn cell, motoneuron. (05 Mar 2000) |
| Bender Visual Motor Gestalt test | <psychology> A psychological test used by neurologists and clinical psychologists to measure a person's ability to visually copy a set of geometric designs. It consists of nine geometric designs on cards. The subject is asked to redraw them from memory after each one is presented individually. It is useful for measuring visuospatial and visuomotor coordination to detect brain damage. Synonym: Bender Visual Motor Gestalt test. (14 Aug 2000) |
| gamma motor neurons | The reflex arc consisting of small anterior horn cells and neuroma, their small fibres projecting to the intrafusal bundle producing its contraction, which initiates the afferent impulses that pass through the posterior root to the anterior horn cells, inducing a stretch reflex. Synonym: gamma motor neurons, gamma motor system, Granit's loop. (05 Mar 2000) |
| gamma motor system | The reflex arc consisting of small anterior horn cells and neuroma, their small fibres projecting to the intrafusal bundle producing its contraction, which initiates the afferent impulses that pass through the posterior root to the anterior horn cells, inducing a stretch reflex.
