| inferior fascia of urogenital diaphragm | The layer of fascia extending between the ischiopubic rami inferior to the sphincter urethrae and the deep transverse perineal muscles.

| field diaphragm | <microscopy> In a photomicrographic system particularly, an iris diaphragm that is imaged in the field of view with Kohler illumination. This limits the extent of the illuminated field and eliminates much extraneous light. The iris diaphragm that is located in front of the collecting lens of the light source. With Kohler illumination, the condenser focuses the image of the field diaphragm onto the image plane. (05 Aug 1998) |

| lumbar part of diaphragm | The portion of the diaphragm that arises from the upper lumbar vertebrae and from the medial and lateral arcuate ligaments. See: right crus of diaphragm, left crus of diaphragm, lateral arcuate ligament, medial arcuate ligament. Synonym: pars lumbalis diaphragmatis, vertebral part of diaphragm. (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. Synonym: acousticopalpebral reflex, auropalpebral reflex, cochleo-orbicular reflex, startle reflex. (05 Mar 2000) |
