In the past few decades, sonography has made some tremendous advances. A use that not many have thought about is for astronauts in space. With longer human stays in space and prospects of long term space travel, some thought it would be a great idea to have medical imaging for the space travelers. Ultrasound was chosen because it encompasses a broad base of pathologies. In 2001, NASA integrated an ultrasound into the Health Research Facility on the International Space Station with the hopes of…

Natural selection is very important in the addition of adaptations to bring forth more able and stronger individuals that can survive in their harsh environment. Selection can make some organisms deadlier, like the Asian giant hornet, or can make other organisms better at finding food in hard to reach areas, such as woodpeckers with thicker skulls. Each of these adaptations are unique to these organisms because these adaptations allow them to live in their unique niches. For natural selection to…

pigment epithelium. The important function of ciliary epithelium is to produce aqueous humor. Aqueous humor is required to build up the intraocular pressure (IOP), that maintains the eye shape, and also nourishes avascular eye tissues, like lens and cornea. Ciliary muscle helps for proper accommodation of lens (Janssen et al. 2012). Previous studies reports , CB synthesizes and expresses multiple neuro endocrine proteins such as different as neurotensin, natriuretic peptides,and…

many effects ranging from redness in their eyes to blindness. Having mentioned this, the article then goes on to tell us about a specific alternative to rabbits that was developed, the Bovine Corneal Opacity and Permeability test. This test uses the cornea of slaughtered byproducts to test the effects of cosmetics. The article mentions that this test provided very reliable results and has led many cosmetics companies to look into alternatives for their products. One such company mentioned was…

pupil response examination where the physician shines a bright light at the eye and reviews pupil dilation or the absence thereof (Miller and Truog, 2012). A corneal reflex test examines the responsiveness of a patient when a cotton swab touches the cornea; a typical patient will blink, whereas a brain-dead patient will have no response (Miller and Truog, 2012). The oculocephalic test is a procedure where the patients head is turned side to side and typically the patient’s eyes would follow the…
