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 ...
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 ]
Pharyngeal reflex — also known as the gag reflex. Photic sneeze reflex — a sneeze caused by sudden exposure to bright light. Plantar reflex — in infants up to 1 year of age, a curling of the toes when something rubs the ball of the foot. Pupillary accommodation reflex — a reduction of pupil size in response to an object coming close to ...
Grasp reflex. Newborn babies have a number of other reflexes which are not seen in adults, referred to as primitive reflexes. These automatic reactions to stimuli enable infants to respond to the environment before any learning has taken place. They include: Asymmetrical tonic neck reflex; Palmomental reflex; Moro reflex, also known as the ...
Hyperreflexia is overactive or overresponsive bodily reflexes. Examples of this include twitching and spastic tendencies, which indicate disease of the upper motor neurons and the lessening or loss of control ordinarily exerted by higher brain centers of lower neural pathways. [citation needed] Spinal cord injury is the most common cause of ...
A baby born at full-term may commonly exhibit symptoms such as mottling (net-like bluish-red skin due to swollen blood vessels), [6] irritability, trembling, excessive or high-pitched crying, sleeping problems, increased muscle tone, overactive reflexes, seizures, yawning, stuffy nose, sneezing, poor feeding, rapid breathing, slow weight gain ...
Infants therefore utilize the gag reflex for learning three important concepts: the borders of their mouth, desensitizing their gag reflex, and how to protect their airway when volitionally swallowing solid foods. [4] As infants get closer to one year old, the gag reflex moves posteriorly, closer to the laryngeal vestibule.
