Triceps reflex - Wikipedia
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]
Deep Tendon Reflexes - Stanford Medicine 25
There are five deep tendon reflexes and a number of superficial and visceral reflexes covered here. The reflex exam is fundamental to the neurological exam and important to locating upper versus lower motor neuron lesions.

2023年8月28日 · A musculocutaneous nerve injury can affect the biceps reflex, and a radial nerve injury can affect the triceps or brachioradialis reflex, depending on the anatomical area of damage in the nerve. Femoral nerve lesions can affect the patellar reflex, and tibial nerve lesions can affect the ankle reflex.

Triceps Reflex. Support the patient's forearm by cradling it with yours or by placing it on the thigh, with the arm midway between flexion and extension. Identify the triceps tendon at its insertion on the olecranon, and tap just above the insertion. There is extension of the forearm.
Triceps brachii - Physiopedia
The triceps reflex, elicited by sharply striking the triceps tendon, is often used to test the function of the nerves of the arm. This reflex tests spinal nerves C6 and C7, predominately C7. The reflex is tested by abducting the patient's shoulder and elbow to 90 degrees.

2023年7月24日 · In other words, a lesion at C5 would cause hyporeflexia in the biceps reflex (C5-C6) but could produce hyperreflexia in the triceps reflex. This is because the lesion is above the spinal segments (C7-C8) that contribute to the lower motor neuron reflex arc but would affect the upper motor neuron modulation (which are generally inhibitory ...
Triceps Deep Tendon Reflex Assessment - Registered Nurse RN
Why do nurses assess the deep tendon reflexes? It helps evaluate the lower motor neurons/fibers at certain levels of the body. For example, the triceps reflex evaluates C7 to C8, and the brachioradialis reflex evaluate C5 to C6. Grading Scale for Deep Tendon Reflexes. 4+ Hyperactive (clonus) 3+ Brisker than normal (hyperreflexive) 2+ NORMAL
Deep Tendon Reflex: The Tools and Techniques. What Surgical …
Triceps Reflex. Striking point: Triceps tendon above its insertion on the olecranon process of the ulna. Myotome: C7/C8. Peripheral nerve: Radial nerve. Effector: Triceps muscle. Technique: Support the patient’s arm midway between flexion and extension. Allow the elbow to flex about 40° Strike the tendon with the broad end of the Taylor hammer
Triceps reflex - (Anatomy and Physiology I) - Fiveable
The triceps reflex is a deep tendon reflex that involves the contraction of the triceps muscle in response to a stimulus applied to the triceps tendon, usually via a sharp tap with a reflex hammer. This reflex test is used to assess the integrity of the C6 and C7 spinal nerves and is an important component of neurological examinations.
Triceps brachii muscle: Attachments, supply and functions
2023年10月30日 · The triceps brachii muscle consists of a long, medial and lateral head, that originate from their respective attachments on the humerus and scapula, and insert via a common tendon on the ulna. The main function of triceps brachii is …
