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.
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 ]
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
It can be detected through the use of a reflex hammer and is the opposite of hyperreflexia. [ citation needed ] Hyporeflexia is generally associated with a deficit in the lower motor neurons (at the alpha motor neurons from the spinal cord to a muscle), whereas hyperreflexia is often attributed to lesions in the upper motor neurons (along the ...
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.
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 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 .
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 .
