Biceps reflex is a test that examines the function of the C5 and C6 spinal nerves and the biceps brachii muscle. It is performed by tapping the tendon hammer on the biceps tendon and observing the reflex contraction and jerk of the forearm.
The musculocutaneous nerve is a mixed nerve that arises from the lateral cord of the brachial plexus and provides motor innervation to the biceps brachii and other muscles of the arm. It also supplies sensation to the lateral forearm and can be injured by various mechanisms.
Cushing reflex is a physiological response to increased intracranial pressure that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia. It can indicate imminent brain herniation or ischemia and is often seen in acute head injury or neurosurgery.
Hoffmann's reflex, also known as Hoffmann's sign or finger flexor reflex, is a neurological test that can indicate issues with the corticospinal tract. Learn how to perform the test, interpret the results, and compare it with the Babinski sign.
A neurological examination is the assessment of sensory and motor responses to determine whether the nervous system is impaired. It includes a physical examination, a review of the patient's history, and specific tests of mental status, cranial nerves, motor system, sensation, cerebellum, and gait.
A nerve conduction study (NCS) is a medical test to evaluate the function and velocity of motor and sensory nerves. NCS measures nerve conduction velocity (NCV), which is the speed of electrical impulses along a nerve, and can help diagnose various nerve disorders.
The Moro reflex is an infantile reflex that involves spreading and pulling the arms and crying when the infant loses support. It develops between 28 and 32 weeks of gestation and disappears at 3–6 months of age. It is used to evaluate the central nervous system and detect neurological problems.
Learn about the causes, symptoms, and types of brachial plexus injury, a nerve damage that affects the shoulder, arm, and hand. Find out how it can occur during birth, trauma, or tumours, and what are the treatment options.
