During laryngoscopy with conventional Macintosh blade, its tip is placed in the vallecullae to lift the epiglottis which stimulates the stretch receptors
in the epipharynx.
In the theory, the pelvic floor muscle forces the vaginal membrane to stretch against the suspensory ligaments to stimulate the micturition stretch receptors
. Laxity in the membrane or suspensory ligaments may activate stretch receptors
, which are perceived by the cortex as urgency, frequency, and nocturia untimely.
Basically, these are annulospiral stretch receptors
with Ia afferent fibers, synapse in the SC and an efferent axon of lower a motor neuron that causes muscle contraction.
The muscle spindles are the primary stretch receptors
of the skeletal muscles and are arranged parallel to the muscle fibers (2,24).
Yoga includes stretching and prolonged physical postures which lengthens major muscle groups and activates the stretch receptors
in muscles, ligaments and joints, leading to improved physical strength and flexibility (Luskin et al., 2000; Tran, Holly, Lashbrook, & Amsterdam, 2001).
Exaggerated expiration followed by deep inspiration may be triggering pulmonary stretch receptors
eliciting the classic Hering-Breuer reflex, a vagally mediated reflex that results in bradycardia and hypotension (1).
In the lung, stretch receptors
in the airway smooth muscle and irritant receptors found adjacent to bronchial epithelial cells stimulate increases in minute ventilation when the lung is in need of a stretch or deep breath for muscle tenor.
Further, the lung's inflation, activating the stretch receptors
in the bronchi and bronchioles, can stimulate the Hering-Breuer reflex, which should inhibit the normal respiratory pattern and should also inhibit hiccup .
In the tracheobronchial tree and lung, slowly adapting (SARs) and rapidly adapting stretch receptors
(RARs) act in opposing manner on the airway tone: the former mediates bronchodialation, while the latter brochoconstriction.
Because large amount of blood is in the venous system so this effect predominates and there is decrease in right sided filling pressure and hence intracardiac stretch receptors
reflexly decrease heart rate16.
(2000) Long-latency component of the stretch reflex in human muscle is not mediated by intramuscular stretch receptors
. Journal of Neurophysiology 84(1), 184-188.
The foreskin is replete with blood vessels and specialized nerves such as stretch receptors
. The foreskin is, and circumcision removes, the most sensitive part of the penis.
