| filar micrometre ocular | <microscopy> A micrometre ocular with crossed lines which can be simultaneously focused in and moved across the field by means of a micrometre screw. The amount of displacement can be read in 0.01 steps on the micrometre drum head. This makes a very delicate measuring device, since calibration of the micrometre scale by means of a stage micrometre gives values for each interval on the drum head which are much less than the resolving power of the highest-aperture objectives. (05 Aug 1998) |
| fixational ocular movement | Rotation of the eyes during voluntary fixation on an object; tremors, flicks, and drifts occur. (05 Mar 2000) |
| 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) |
| anal region | The posterior portion of the perineal region through which the anal canal opens; bounded by a line through both isehial tuberosities, the sacrotuberous ligaments and the coccyx. Synonym: regio analis, anal region. (05 Mar 2000) |
| ankle region | The region of the lower limb between the leg (crus) and the foot (pes). Synonym: regio talocruralis. (05 Mar 2000) |

| anterior hypothalamic region | The rostral portion of the hypothalamus that includes preoptic, supraoptic, paraventricular and anterior hypothalamic nuclei; the hypothalamic structures located internally in the general area of the optic chiasm. (05 Mar 2000) |
| anterior knee region | The anterior region of the knee. Synonym: regio genus anterior. (05 Mar 2000) |
| anterior region of arm | Area between deltoid region superiorly and anterior region of elbow inferiorly. Synonym: facies brachialis anterior, regio brachialis anterior, anterior surface of arm, facies anterior brachii. (05 Mar 2000) |
