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, and other mammalian species.
The stretch reflex (myotatic reflex), or more accurately "muscle stretch reflex", is a muscle contraction in response to stretching a muscle. The function of the reflex is generally thought to be maintaining the muscle at a constant length but the response is often coordinated across multiple muscles and even joints. [ 1 ]
In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. [1] [2] It helps to maintain posture and declines during REM sleep. [3]
“Sitting for more than a couple hours at a time is really injurious to your health,” Dr. Jordan Metzel, a sports medicine physician at the Hospital for Special Surgery in New York, told TODAY ...
Young adults in the U.S. reportedly sit about nine to 10 hours a day, compared to older adults, who sit up to 13 hours a day. And a lot of us know that sitting for long periods of time can be harmful.
A new study suggests that staying in a seated position for long periods of time can lead to a shortened lifespan.
Reciprocal inhibition is a neuromuscular process in which muscles on one side of a joint relax to allow the contraction of muscles on the opposite side, enabling smooth and coordinated movement. [1] This concept, introduced by Charles Sherrington , a pioneering neuroscientist , is also referred to as reflexive antagonism in some allied health ...
Researchers have produced conflicting results when it comes to the best pre-workout stretch. For example, a well-cited August 2003 study showed evidence of static stretching for warm-ups worsening ...
