ExploreLearning is a Charlottesville, Virginia -based company which operates a large library of interactive online simulations for mathematics and science education in grades 3–12 called 'Gizmos'. ExploreLearning also makes Reflex, an online, game-based system for math fact memorization. [1] ExploreLearning is a business unit of Cambium ...
FRAX (fracture risk assessment tool) is a diagnostic tool used to evaluate the 10-year probability of bone fracture risk. It was developed by the University of Sheffield. [1] FRAX integrates clinical risk factors and bone mineral density at the femoral neck to calculate the 10-year probability of hip fracture and the 10-year probability of a ...
Reflex. In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action [1] and nearly instantaneous response to a stimulus. [2] [3] The simplest reflex is initiated by a stimulus, which activates an afferent nerve. The signal is then passed to a response neuron, which generates a response.
Brisk reflexes refer to an above-average response during a reflex test. During a reflex test, your muscle contracts in response to taps from the reflex hammer. Quicker responses overall may lead ...
A FRAX score of more than 5% for a hip fracture at age 70 and beyond means you should consider treatment along with lifestyle changes. A lower FRAX score, but at a younger age, may also require ...
Reflex syncope is a brief loss of consciousness due to a neurologically induced drop in blood pressure and/or a decrease in heart rate. Before an affected person passes out, there may be sweating, a decreased ability to see, or ringing in the ears. Occasionally, the person may twitch while unconscious.
Hoffmann's reflex. Hoffmann's reflex ( Hoffmann's sign, sometimes simply " Hoffmann's ", also finger flexor reflex) [1] is a neurological examination finding elicited by a reflex test which can help verify the presence or absence of issues arising from the corticospinal tract. It is named after neurologist Johann Hoffmann. [2]
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. The brain will receive the input while the ...
