Retroreflector A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering.n alternative form of the cat's eye retroreflector uses a normal lens focused onto a curved mirror rather than a transparent sphere, though this type is much more limited in the range of incident angles over which it retroreflects.

- The baroreceptor reflex or baroreflex is the body's way of responding to a change in blood pressure. Baroreceptors in the arteries notice that something has changed. When they sense a change in pressure, they send out signals through nerves to a part of the brain called the brainstem.

- ARPWAVE Neuro Therapy will determine the origin of the signal which is causing restricted ROM or pain. Treatment: Once the signal is identified the patient must neurologically reeducate the muscles to absorb force and break all neuro compensation patterns. That is why the ARPWAVE Neuro Therapy can be a great addition to your practice.

Apollo 11 Mission Science Experiments-Laser Ranging Retroreflector. The Laser Ranging Retroreflector experiment was deployed on Apollo 11, 14, and 15. It consists of a series of corner-cube reflectors, which are a special type of mirror with the property of always reflecting an incoming light beam back in the direction it came from.he Laser Ranging Retroreflector experiment has produced many important measurements. These include an improved knowledge of the Moon's orbit and the rate at which the Moon is receding from Earth (currently 3.8 centimeters per year) and of variations in the rotation of the Moon.

Definitions &Translations Retrograde amnesia is the inability to retrieve information that was acquired before a particular date, usually the date of an accident or operation. In some cases the memory loss can extend back decades, while in others the person may lose only a few months of memory. Anterograde amnesia is the inability to transfer new information from the short-term store into the long-term store. People with this type of amnesia cannot remember things for long periods of time.

What is a Balfour Retractor? A Balfour retractor is a surgical instrument which is used by a surgeon to hold open abdominal incisions during a laparotomy. Retractors of all shapes and sizes are used to clearly expose the surgical site during surgeries so the surgeon can see what he or she is doing, and they work in a variety of ways.

As the largest (105 x 65 cm in size) it serves as the primary target for laser ranging to the Moon.he Apollo 15 array is one of four usable such arrays on the Moon. The others are at the Apollo 11 and Apollo 14 sites, and on the Lunokhod 2 rover. A portion of the Apollo 15 lunar laser ranging retroreflector array, as placed on the Moon and photographed by D.

Hyporeflexia Hyporeflexia is among the possible response in deep tendon test and is the reverse of hyperreflexia. The condition of hyporeflexia is an indication of a problem with the reflex arc itself whereas hyperreflexia represents a problem with the spine located on top of the reflex. A reflex is an involuntary or automatic movement when a stimulus is applied.

Baroreflex The baroreflex or baroreceptor reflex is one of the body's homeostatic mechanisms that helps to maintain blood pressure at nearly constant levels. The baroreflex provides a rapid negative feedback loop in which an elevated blood pressure reflexively causes the heart rate to decrease and also causes blood pressure to decrease.

- A retrolisthesis is a posterior displacement of one vertebral body with respect to the adjacent vertebrae to a degree less than a luxation (dislocation) .igns and symptoms [edit]. Retrolisthesis may lead to symptoms of greatly varying intensity and distribution. This is because of the variable nature of the impact on nerve tissue and of the mechanical impact on the spinal joints themselves.

What is an: Autorefractor Autorefractors are machines that automatically determine the correct lens prescription for your eyes. If you've discovered you might need vision correction during your eye examination, it's vital to determine just how much your eyes need to be corrected with lenses or contact lenses. This is called measuring your refraction.. Autorefractors automatically measure this value during an eye examination.
