tendon reflex

{{Short description|Reflexes in physiology}}

Tendon reflex (or T-reflex) may refer to:

• The stretch reflex or muscle stretch reflex (MSR), when the stretch is created by a blow upon a muscle tendon. This is the commonly used definition of the term.[http://medical-dictionary.thefreedictionary.com/tendon+reflex TheFreeDictionary > tendon reflex] Citing: Dorland's Medical Dictionary for Health Consumers. 2007[http://dictionary.reference.com/browse/tendon+reflex dictionary.com > tendon reflex] Citing: Merriam-Webster's Medical Dictionary, 2007 and The American Heritage Stedman's Medical Dictionary 2002 Albeit a misnomer, in this sense a common example is the standard patellar reflex or knee-jerk response.[http://neuromuscular.wustl.edu/mother/reflex.html wustl.edu > tendon reflex] Citing: wustl.edu. REFLEXES: Tendon & Other. 2008. 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.[http://www.enotes.com/reflex-tests-reference/reflex-tests-172354 eNotes > tendon reflex] Citing: Encyclopedia of Nursing and Allied Health. 2002

::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 responsible for mechanically transmitting the sudden stretch from the reflex hammer to the muscle spindle. In addition, some muscles with stretch reflexes have no tendons (e.g., "jaw jerk" of the masseter muscle)".[https://www.clinicalkey.com/#!/content/book/3-s2.0-B9780323392761000639?indexOverride=GLOBAL Evidence-Based Physical Diagnosis; McGee; Chapter 63. 2018]

• The Golgi tendon reflex, which is a reflex to extensive tension on a tendon; it functions to protect musculoskeletal integrity. The sensory receptors for this reflex are anatomically located deep in the tendon, while the sensory receptors for the MSR are inside the muscle. Therefore, the Golgi tendon reflex can be referred to as the deep tendon reflex.
