  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 ]

  3. Bainbridge reflex - Wikipedia

    en.wikipedia.org/wiki/Bainbridge_reflex

    It is detected by stretch receptors in the wall of the right atrium, the afferent limb is via the vagus nerve, it is regulated by a center in the medulla oblongata of the brain, [1] and the efferent limb involves reduced vagal activity and increased sympathetic nervous system outflow. [2]

  4. Muscle spindle - Wikipedia

    en.wikipedia.org/wiki/Muscle_spindle

    Muscle spindles are stretch receptors within the body of a skeletal muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via afferent nerve fibers. This information can be processed by the brain as proprioception.

  5. Proprioception - Wikipedia

    en.wikipedia.org/wiki/Proprioception

    For example, consider the stretch reflex, in which stretch across a muscle is detected by a sensory receptor (e.g., muscle spindle, chordotonal neurons), which activates a motor neuron to induce muscle contraction and oppose the stretch. During locomotion, sensory neurons can reverse their activity when stretched, to promote rather than oppose ...

  6. Mechanoreceptor - Wikipedia

    en.wikipedia.org/wiki/Mechanoreceptor

    Chordotonal organs: Internal stretch receptors at the joints, can have both extero- and proprioceptive functions. The neurons in the chordotonal organ in Drosophila melanogaster can be organized into club, claw, and hook neurons. Club neurons are thought to encode vibrational signals while claw and hook neurons can be subdivided into extension ...

  7. Stimulus (physiology) - Wikipedia

    en.wikipedia.org/wiki/Stimulus_(physiology)

    Blood pressure, heart rate, and cardiac output are measured by stretch receptors found in the carotid arteries. Nerves embed themselves within these receptors and when they detect stretching, they are stimulated and fire action potentials to the central nervous system. These impulses inhibit the constriction of blood vessels and lower the heart ...

  8. Reflex - Wikipedia

    en.wikipedia.org/wiki/Reflex

    This information can be detected using electromyography (EMG). [9] 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)

  9. 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 ...
