[citation needed] This reflex may also be impaired by damage to the internal branch of the superior laryngeal nerve which relays the afferent branch of the reflex arc. [ citation needed ] This nerve is most commonly damaged by swallowing a foreign object, such as a chicken bone, resulting in it being lodged in the piriform recess (in the ...
The gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. Touching the soft palate can lead to a similar reflex response. However, in that case, the sensory limb of the reflex is the CN V (trigeminal nerve). In very sensitive ...
Palmar grasp reflex — in infants up to six months of age, a closing of the hand in response to an object being placed in it. Periroral reflex: when a finger is placed at the angle of the mouth and struck, or the nasolabial fold is stroked, mouth closure is induced via CN VII [1] Pharyngeal reflex — also known as the gag reflex.
A main reason is that patients’ cough reflex is enhanced for a month or more even from the simplest common cold, said Dr. Peter Dicpinigaitis, director of Montefiore Cough Center in New York City.
Airway clearance therapy is treatment that uses a number of airway clearance techniques to clear the respiratory airways of mucus and other secretions. [1] Several respiratory diseases cause the normal mucociliary clearance mechanism to become impaired resulting in a build-up of mucus which obstructs breathing, and also affects the cough reflex.
Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli. These reflexes are suppressed by the development of the frontal lobes as a child transitions normally into child development . [ 1 ]
The exact location and functionality of the cough center has remained somewhat elusive: while Johannes Peter Müller observed in 1838 that the medulla coordinates the cough reflex, investigating it has been slow because the usual anaesthetics for experimental animals were morphine or opiates, drugs which strongly inhibit cough.
The principles of systematic desensitization can be used by children to help reduce their test anxiety. Children can practice the muscle relaxation techniques by tensing and relaxing different muscle groups. With older children and college students, an explanation of desensitization can help to increase the effectiveness of the process.
