| accommodation of eye | The increase in thickness and convexity of the eye's lens in order to focus the image of an external object upon the retina. (05 Mar 2000) |
|---|---|
| accommodation of nerve | <anatomy, nerve> The property of a nerve by which it adjusts to a slowly increasing strength of stimulus, so that its threshold of excitation is greater than it would be were the stimulus strength to have risen more rapidly. (05 Mar 2000) |
| accommodation reflex | Increased convexity of the lens, due to contraction of the ciliary muscle and relaxation of the suspensory ligament, to maintain a distinct retinal image. (05 Mar 2000) |
| accommodative convergence-accommodation ratio | The amount of convergence (measured in prism diopters of convergence) divided by the amount of accommodation (measured in diopters) required to direct both eyes upon an object. (05 Mar 2000) |
| amplitude of accommodation | The difference in refractivity of the eye at rest and when fully accommodated. (05 Mar 2000) |
| range of accommodation | The distance between an object viewed with minimal refractivity of the eye and one viewed with maximal accommodation. (05 Mar 2000) |
| relative accommodation | Quantity of accommodation required for single binocular vision for any specified distance, or for any particular degree of convergence. (05 Mar 2000) |
| positive accommodation | The increased refractivity of the eye that occurs when shifting from the distance to a near object. (05 Mar 2000) |
| Helmholtz theory of accommodation | That the ciliary muscle relaxes for near vision and allows the anterior aspect of the lens to become more convex. (05 Mar 2000) |
| histologic accommodation | The change in shape of cells to meet altered physical conditions, as the flattening of cuboidal cells in cysts as a result of pressure. Synonym: pseudometaplasia. (05 Mar 2000) |
| spasm of accommodation | Excessive contraction of the ciliary muscle. (05 Mar 2000) |
| negative accommodation | The decrease of accommodation that occurs when shifting from near vision to distance vision. (05 Mar 2000) |
| alveolar point | The most anterior point on the maxillary alveolar process in the midline. Synonym: alveolar point, prostheon. Origin: G. Ntr. Of prosthios, foremost (05 Mar 2000) |
| anterior focal point | The point where parallel rays from the retina are focused. (05 Mar 2000) |
| apophysial point | The centre of the root of the anterior nasal spine. Synonym: apophysary point, apophysial point, spinal point. (05 Mar 2000) |
