  2. Stretch reflex - Wikipedia

    en.wikipedia.org/wiki/Stretch_reflex

    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] The older term deep ...

  3. Patellar reflex - Wikipedia

    en.wikipedia.org/wiki/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, and other ...

  4. Reflex - Wikipedia

    en.wikipedia.org/wiki/Reflex

    Generally, decreased reflexes indicate a peripheral problem, and lively or exaggerated reflexes a central one. [9] A stretch reflex is the contraction of a muscle in response to its lengthwise stretch. Biceps reflex (C5, C6) Brachioradialis reflex (C5, C6, C7) Extensor digitorum reflex (C6, C7) Triceps reflex (C6, C7, C8)

  5. List of reflexes - Wikipedia

    en.wikipedia.org/wiki/List_of_reflexes

    Stretch reflex; Triceps reflex — jerking of the forearm when the triceps tendon is hit with a tendon hammer, stimulating the C7 and C6 reflex arcs. Vagovagal reflex — contraction of muscles in the gastrointestinal tract in response to distension of the tract following consumption of food and drink. Vestibulocollic reflex; Vestibulo-spinal ...

  6. Ankle jerk reflex - Wikipedia

    en.wikipedia.org/wiki/Ankle_jerk_reflex

    It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it. A positive result would be the jerking of the foot towards its plantar surface. Being a deep tendon reflex, it is monosynaptic. It is also a stretch reflex. These are monosynaptic spinal segmental reflexes.

  7. Golgi tendon organ - Wikipedia

    en.wikipedia.org/wiki/Golgi_tendon_organ

    The Ib sensory feedback generates stretch reflexes and supraspinal responses which control muscle contraction. Ib afferents synapse with interneurons in the spinal cord that also project to the brain cerebellum and cerebral cortex. The Golgi tendon reflex assists in regulating muscle contraction force. It is associated with the Ib.

  8. Tendon reflex - Wikipedia

    en.wikipedia.org/wiki/Tendon_reflex

    Stretch reflex tests are used to determine the integrity of the spinal cord and peripheral nervous system, and they can be used to determine the presence of a neuromuscular disease. [4] The term "deep tendon reflex", if it refers to the muscle stretch reflex, is a misnomer. "Tendons have little to do with the response, other than being ...

  9. Jendrassik maneuver - Wikipedia

    en.wikipedia.org/wiki/Jendrassik_maneuver

    The elicited response is compared with the reflex result of the same action when the maneuver is not in use. Often a larger reflex response will be observed when the patient is occupied with the maneuver: "A weak or apparently missing reflex could be triggered by afferent activity resulting from such muscle tension.
