The brachioradialis reflex (also known as supinator reflex [1]) is observed during a neurological exam by striking the brachioradialis tendon (at its insertion at the base of the wrist into the radial styloid process (radial side of wrist around 4 inches proximal to base of thumb)) directly with a reflex hammer when the patient's arm is relaxing.
Two-point discrimination ( 2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It is often tested with two sharp points during a neurological examination [ 1 ]: 632[ 2 ]: 71 and is assumed to reflect how finely innervated an area of skin is.
Radial dysplasia, also known as radial club hand or radial longitudinal deficiency, is a congenital difference occurring in a longitudinal direction resulting in radial deviation of the wrist and shortening of the forearm. It can occur in different ways, from a minor anomaly to complete absence of the radius, radial side of the carpal bones and ...
Allen's test. Arteries of the hand. Purpose. examination of arterial blood flow to the hands. In medicine, Allen's test or the Allen test is a medical sign used in physical examination of arterial blood flow to the hands. It was named for Edgar Van Nuys Allen, who described the original version of the test in 1942. [ 1]
A simple homemade eight-arm radial arm maze with sidewalls to prevent interarm traverses. The radial arm maze was designed by Olton and Samuelson in 1976 to measure spatial learning and memory in rats. [1] The original apparatus consists of eight equidistantly spaced arms, each about 4 feet long, and all radiating from a small circular central ...
24336-0. An arterial blood gas ( ABG) test, or arterial blood gas analysis ( ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, [ 1] but sometimes the femoral artery in the groin or another site is used.
Purpose. analyzes the motion of tissues in the heart. In the fields of cardiology and medical imaging, speckle tracking echocardiography ( STE) is an echocardiographic imaging technique. It analyzes the motion of tissues in the heart by using the naturally occurring speckle pattern in the myocardium (or motion of blood when imaged by ultrasound ).
Cervical spinal nerve 8. The plan of the cervical and brachial plexuses. The spinal cord with spinal nerves. The cervical spinal nerve 8 (C8) is a spinal nerve of the cervical segment. [ 1] It originates from the spinal column from below the cervical vertebra 7 (C7).
