Role of the Blood-Brain Barrier in the Formation of Brain Metastases
WebbBaroreceptors (or venoatrial stretch receptors) are pressure sensors found in the right atrium of the heart that sense changes in the volume and pressure of blood returning to the heart. These receptors send signals to the central nervous system via the vagus nerve (10th cranial nerve). Changes in baroreceptor activity may also trigger a reflex ... WebbThe reflex response that is produced is apnea followed by rapid breathing, bradycardia, and hypotension (pulmonary chemoreflex). The physiologic role of this reflex is uncertain, … my math math book
Juxtacapillary receptors - Wikipedia
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… WebbSlowly adapting (pulmonary stretch) receptors (SARs) are mechanoreceptors that lie within the submucosal smooth muscles in the membranous posterior wall of the trachea and central airways (Bartlett et al., 1976). A small proportion of the receptors are located in the extrathoracic upper trachea (Berger, 2000). WebbCapsaicin was injected intravenously to stimulate lung C-fibre receptors, and veratrine to stimulate pulmonary stretch receptors and cardiac receptors . Acetazolamide treatment (20 mg/kg) diminished the inhibitory responses of slowly adapting pulmonary stretch receptors to CO2 inhalation , which were not significantly influenced by pretreatment … my math path 7a
