“…While the responses to lengthening are most likely associated with the excitability of II afferents from the muscle spindles, the neural substrates of the ShR are not fully understood. The ShR can be induced at relatively low velocities of imposed joint rotations, and the role of Golgi tendon organs [70], group II muscle afferents [71], and joint receptors [34] in its generation have been previously discussed in the context of its functional role as an adaptation reflex of muscle to its length [47]. It has also been noted that ShR is accompanied by a discharge of primary endings of muscle spindles due to α-γ coactivation [72].…”

Manifestation of muscle reactions at an early developmental stage may reflect the processes underlying the generation of appropriate muscle tone, which is also an integral part of all movements. In preterm infants, some aspects of muscular development may occur differently than in infants born at term. Here we evaluated early manifestations of muscle tone by measuring muscle responses to passive stretching (StR) and shortening (ShR) in both upper and lower limbs in preterm infants (at the corrected age from 0 weeks to 12 months), and compared them to those reported in our previous study on full-term infants. In a subgroup of participants, we also assessed spontaneous muscle activity during episodes of relatively large limb movements. The results showed very frequent StR and ShR, and also responses in muscles not being primarily stretched/shortened, in both preterm and full-term infants. A reduction of sensorimotor responses to muscle lengthening and shortening with age suggests a reduction in excitability and/or the acquisition of functionally appropriate muscle tone during the first year of life. The alterations of responses during passive and active movements in preterm infants were primarily seen in the early months, perhaps reflecting temporal changes in the excitability of the sensorimotor networks.

“…Sometime for example the gag reflex may be due to medical problem. (9,10) This study was to evaluate the gag reflex as a problem and methods used to control it, in order to allow the patient to receive dental care such as fillings, extractions, impression, teeth cleaning and root canals with a minimum of anxiety and stress.…”

Aims: To assess gag reflex as a problem in patients undergoing dental treatment and some measures used to control it in order to allow the patient to receive dental care such as taking anesthesia, fillings, extractions, impression, scaling and polishing of teeth and root canals. Materials and Methods: The sample chosen included 80 people between the ages 20 and 65 attended to dental clinics for fillings, extractions, impression, scaling and polishing and root canals during dental treatment these patients complained an exaggerated gag reflex. Results: In control group there was no significant difference between females and males regarding the age and duration of gag reflex, but significantly correlated in study group as a whole concerning the age and duration of gag reflex. Conclusions: Gag reflex is considered as normal defense mechanism that prevents foreign bodies from entering the trachea, pharynx or larynx.
