Head Mirror with head band: to focus light into the cavity under inspection; mirror is concave and is used with a Chiron lamp to produce a parallel beam of light; doctor views through the hole (average diameter of mirror is 3 & 1/2" & that of hole is 1/4") Head mounted lights with head band: to focus light into the cavity under inspection ...
The hamadryas baboon is one of many primate species that has been administered the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. to determine whether an animal possesses the ability of visual self-recognition.

A combined rapid anterior pituitary evaluation panel or triple bolus test or a dynamic pituitary function test is a medical diagnostic procedure used to assess a patient's pituitary function. A triple bolus test is usually ordered and interpreted by endocrinologists. [citation needed] In rare cases, it has been associated with pituitary ...
The anterior chamber drainage angle is then graded as a ratio between the peripheral anterior chamber depth and corneal thickness (AC : C ratio) [5] or expressed traditionally as a fraction [6] to provide the Van Herick's result. Grading can also be obtained by distinguishing the structures visible upon observation.
The most widely used method in the United States is based on the work of Exner. Administration of the test to a group of subjects, by means of projected images, has also occasionally been performed, but mainly for research rather than diagnostic purposes. [26] Test administration is not to be confused with test interpretation:
Entoptic images have a physical basis in the image cast upon the retina. Hence, they are different from optical illusions, which are caused by the visual system and characterized by a visual percept that (loosely said) appears to differ from reality. Because entoptic images are caused by phenomena within the observer's own eye, they share one ...
It wasn’t until her ob-gyn used the Tyrer-Cuzick Risk Assessment Calculator—a simple tool that concluded Munn had a 37% chance of developing breast cancer—that she pursued additional testing ...
The first hypothesis came from Tickle et al. who showed that when retinoic acid is placed in the anterior margin of the limb bud, mirror image duplications result. [6] However, concentrations of retinoic acid that cause mirror image duplications induce high levels of a downstream gene, retinoic acid receptor Beta, which is not seen in the ...
