WebbNervous receptors in the lungs and respiratory tract can be grouped into four general categories. 1. Deep, slowly adapting end-organs, which respond to stretch of the airway wall and have large-diameter myelinated fibres; those in the lungs are responsible for the Breuer-Hering reflex. 2. Endings in … Webb22 juni 2024 · Receptors, which are required for binding neuro molecules released from producer neurons or other cells to get downstream effects in the target immune cells, are divided into (1) ionotropic and (2) metabotropic, where ionotropic receptors have been historically subdivided into (i) ligand-gated (so far, it is the prevalent subtype), (ii) voltage …

Pulmonary stretch receptors are mechanoreceptors found in the lungs. When the lung expands, the receptors initiate the Hering-Breuer reflex, which reduces the respiratory rate. This signal is transmitted by vagus nerve. Increased firing from the stretch receptors also increases production of pulmonary surfactant. Intercostal muscles and thoracic diaphragm receive impulses from the respiratory center, stretch receptors in the lungs send impul… Webb1 juli 2003 · Pulmonary stretch receptors were activated by tonically inflating the lungs with air, achieved by setting the outflow pressure at either 1 or 10 cmH 2 O. Tests were not conducted until 3–5 min after changes in tracheal pressure, to avoid potential influences of phasic changes in pulmonary volume.

WebbAirway tissue obtained postmortem from nondiseased and severely asthmatic human lung was used in functional, radioligand binding and autoradiographic studies to investigate aspects of various receptor systems for putative mediators of asthma. Webb1 aug. 1999 · Although feedback from pulmonary stretch receptors and direct respiratory-related changes in venous return and cardiac stretch can evoke respiratory related fluctuations in heart rate, the dominant source of respiratory sinus arrhythmia originates from the brain stem ( 2 ).

WebbPulmonary stretch receptors trigger vagal afferents that lead to termination of inhalation. The medullary respiratory centers send efferent signals out to the intercostal muscles and diaphragm for modulation of the respiratory pattern during both wake and sleep.68 These inflation-deflation reflexes have been referred to as the Hering-Breuer reflex.
