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. [1] [2] Albeit a misnomer, in this sense a common example is the standard patellar reflex or knee-jerk response. [3]
Glabellar reflex; Golgi tendon reflex; Hanger reflex - reflex of unclear purpose that causes the head to rotate to the right when the top sides of the head are under pressure, named because it can be easily activated with a coat hanger; Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung
Biceps reflex is a deep tendon reflex (DTR) test (also known as a muscle-stretch reflex test) [1] that examines the function of the C5 reflex arc and the C6 reflex arc. [2] The test is performed by using a tendon hammer to quickly depress the biceps brachii tendon [ 3 ] as it passes through the cubital fossa .
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 medicine, reflexes are often used to assess the health of the nervous system. Doctors will typically grade the activity of a reflex on a scale from 0 to 4. While 2+ is considered normal, some healthy individuals are hypo-reflexive and register all reflexes at 1+, while others are hyper-reflexive and register all reflexes at 3+.
Hoffmann's reflex is a deep tendon reflex (spindle fibre) with a monosynaptic reflex pathway in Rexed lamina IX of the spinal cord, normally fully inhibited by descending input. On the other hand, the plantar reflex is more complicated and not a deep tendon reflex, and its pathway is both more complicated and not fully understood. [8]
The triceps reflex, a deep tendon reflex, is a reflex that elicits involuntary contraction of the triceps brachii muscle. It is sensed and transmitted by the radial nerve. [1] The reflex is tested as part of the neurological examination to assess the sensory and motor pathways within the C7 and C8 spinal nerves. [2]
The Golgi tendon reflex operates as a protective feedback mechanism to control the tension of an active muscle by causing relaxation before the tendon tension becomes high enough to cause damage. [7] First, as a load is placed on the muscle, the afferent neuron from the Golgi tendon organ fires into the central nervous system .
