Thus, the arthrokinetic reflex refers to the involuntary response that happens when a joint is moved, namely that relevant muscles fire reflexively. [citation needed] In 1956, Leonard Cohen and Manfred Cohen discovered that moving a decerebrate cat's knee joint resulted in muscle activation of the quadriceps or semitendinosus, depending on ...
Good-Excellent. Benign fasciculation syndrome ( BFS) is characterized by fasciculation (twitching) of voluntary muscles in the body. [1] The twitching can occur in any voluntary muscle group but is most common in the eyelids, arms, hands, fingers, legs, and feet. The tongue can also be affected.
To test the reflex, the muscle should be in a neutral position. The muscle being tested needs to be flexed for the clinician to locate the tendon. After the muscle is relaxed, the clinician strikes the tendon. The response should be contraction of the muscle. If this is the knee jerk reflex, the clinician should observe a kick.

[2] The word arthritis refers to inflammation of the joints. [3] [4] Types of arthritis include those related to wear and tear of cartilage, such as osteoarthritis, to those associated ...
Patellar reflex. Schematic representation of patellar tendon reflex (knee jerk) pathway. The patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord. Many animals, most significantly humans, have been seen to have the patellar reflex, including dogs, cats, horses ...
Intermittent hydrarthrosis ( IH ), also known as periodic synoviosis, periodic benign synovitis, or periodic hydrarthritis, is a chronic condition of unknown cause characterized by recurring, temporary episodes of fluid accumulation ( effusion) in the knee. While the knee is mainly involved, occasionally other joints such as the elbow or ankle ...
