The reflex with the simplest structure in medicine is called the intrinsic reflex. This means that the reflex occurs in the very place where it was triggered. An example of this is the patellar tendon reflex in the area of the kneecap, which is caused by a light blow on the same. What is an … Intrinsic Reflex: Function, Tasks, Role & Diseases
The biceps tendon reflex is an innate and monosynaptic intrinsic reflex that belongs to the stretch reflexes. Reflectively, the biceps muscle contracts after a blow to the biceps tendon, thereby flexing the forearm at the elbow joint. The biceps tendon reflex may be altered in peripheral and central nerve damage. What is the biceps tendon … Biceps Tendon Reflex: Function, Tasks, Role & Diseases
The orbicularis oris reflex is a pathologic extraneous reflex of the orbicularis oris muscle that is triggered by tapping the corners of the mouth. In neurological diagnostics, the presence of the reflex movement refers to brain-organic damage. Often, the reflex is preceded by causative ischemia in the region of the pons. What is the orbicularis … Orbicularis Oris Reflex: Function, Role & Diseases
When the doctor shines his light into your eyes or uses his reflex hammer, this action, unpleasant in itself, has the goal of checking your reflexes and thus the state of your nervous functions, because the multitude of bodily reactions, most of which are unconscious to us, shows exactly how our brain performance is doing. … Importance of Reflexes in the Body
An intrinsic reflex is characterized by the fact that the stimulus site and the responding organ are identical. Most intrinsic reflexes are muscle stretch reflexes that protect us, in which brief muscle stretch-whether caused by a reflex hammer or a sudden buckling of the knee joint, for example-leads to contraction and thus twitching of the … Reflexes: Intrinsic Reflex and Extrinsic Reflex
Pathological reflexes occur when there is nerve or brain damage. The best known pathological reflex is the Babinski reflex, which causes extension of the big toe and flexion of all other toes when the sole of the foot is brushed. It is one of the early childhood reflexes and is usually not triggerable after 12 … Reflexes: Pathological, Conditioned, Conditioned Reflex
By the cremasteric reflex, physicians mean the polysynaptic external reflex of the cremasteric muscle that moves the testes upward in response to stimuli. The reflex is exhaustible and may therefore be absent due to age physiology. Abnormal reflex behavior of the cremaster muscle, on the other hand, may also indicate spinal cord lesions. What is … Cremasteric Reflex: Function, Tasks, Role & Diseases
The dorsalis pedis reflex is a pathologic intrinsic reflex of the musculi interossei plantares and is one of the pyramidal tract signs. On a healthy adult, the reflex plantar reflex of the toes with a strike to the dorsal side of the foot has little or no triggerability. Triggerability is indicative of pyramidal lesions. What … Dorsal Reflex of the Foot: Function, Tasks, Role & Diseases
The adductor reflex is an intrinsic reflex of the muscles and muscle groups in the thighs and arms known as the adductors. The absence of the reflex indicates damage in the corresponding area of the brain. What is the adductor reflex? The adductor reflex is an intrinsic reflex of the muscles and muscle groups in … Adductor Reflex: Function, Tasks, Role & Diseases
Protective reflexes are autonomic muscle movements triggered by external factors to protect a specific body part. The muscles involved are usually skeletal muscles that normally serve conscious, voluntary movement. Protective reflexes are triggered bypassing consciousness in favor of much higher reaction rates, as in the case of the eyelid closure reflex, which protects the eye … Protective Reflexes: Function, Task & Diseases
The masseter reflex is an intrinsic reflex of the masticatory muscles that is triggered by a blow to the lower jaw and closes the jaw. The reflex is one of the muscle stretch reflexes and corresponds to an innate reflex movement of the masseter muscle. The masseter reflex may be absent in peripheral and central … Masseter Reflex: Function, Tasks, Role & Diseases
The Rossolimo reflex is a plantar muscle reflex of the foot, which is triggered under pathologic conditions. It represents an uncertain pyramidal tract sign and indicates lesions in the pyramidal tract. What is the rosolimo reflex? The Rossolimo reflex is a plantar muscle reflex of the foot, which is triggered under pathologic conditions. The Rossolimo … Rossolimo Reflex: Function, Role & Diseases
