| detrusor pressure | That component of intravesical pressure created by the tension (active and passive) exerted by the bladder wall; the transmural pressure across the bladder wall estimated by subtracting abdominal pressure from intravesical pressure. (05 Mar 2000) |
| detrusor sphincter dyssynergia | A disturbance of the normal relationship between bladder (detrusor) contraction and sphincter relaxation during voluntary or involuntary voiding efforts. (05 Mar 2000) |
| detrusor stability | A detrusor that accommodates increasing bladder volume without significant increase in detrusor pressure and without involuntary detrusor contraction. (05 Mar 2000) |
| abdominocardiac reflex | Mechanical stimulation (usually distention) of abdominal viscera causing changes (usually a slowing) in the heart rate or the occurrence of extrasystoles. (05 Mar 2000) |
| Abrams' heart reflex | A contraction of the myocardium when the skin of the precordial region is irritated. (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) |
| Achilles reflex | A contraction of the calf muscles when the tendo calcaneus is sharply struck. Synonym: ankle jerk, ankle reflex, tendo Achillis reflex, triceps surae reflex. (05 Mar 2000) |
| acousticopalpebral reflex | A form of the wink reflex in which there is a contraction, sometimes very slight, of the orbicularis palpebrarum muscle when a sudden noise is made close to the ear; it is absent in labyrinthine disease with total deafness.
