The genioglossus muscle, for instance, responds to chemoreceptor
stimuli by contracting in order to increase upper airway patency.
The beauty of this method is that a linear relationship has been shown to exist between the minute ventilation (VE) and PCO2 changes of arterial blood and medillary chemoreceptor
To simulate the prehypertensive SS baroreceptor systemic phenotype of partial baroreceptor impairment (10,13), a chronic bilateral aortic denervation was performed instead of a chronic bilateral carotid sinus denervation, because the destruction of chemoreceptors
during the carotid sinus denervation (22,23) in a species like the rat, which lacks functional aortic body chemoreceptors
(25), causes chronic hypoventilation with consequent chronic systemic hypoxia, which in turn has the chronic effect of lowering blood pressure (23).
The marked metabolic acidosis was producing substantial stimulation of the central chemoreceptors
Dopamine receptors are located in the chemoreceptor
trigger zone and dopamine receptor antagonists primarily affect this area; however, high doses of dopamine receptor blockades result in extrapyramidal reactions, disorientation, and sedation, which limit the clinical use of such agents, including phenothiazines and butyrophenones (droperidol and haloperidol) (8).
One of the species has, for example, a spectacular chemoreceptor
, a highly specialised type of the habitual post-antennal organ of the springtails.
In addition, a population of sensory cells called solitary chemoreceptor
cells are found in the posterior portion of the nasopharynx and throughout the respiratory system, and serve to trigger protective reflexes such as coughing and laryngeal closure (62).
Brief episodes of apnea/hypopnea increase SNS activation by suspending the tonic inhibition of sympathetic outflow by pulmonary stretch receptors (37) and by the stimulation of peripheral and central chemoreceptor
Today we know that nausea and vomiting are side-effects of morphine-like drugs since it stimulates the chemoreceptor
trigger zones for emesis (Reisine et al.
Capsaicin is a chemical compound which stimulates chemoreceptor
nerve endings in the skin, especially the mucous membranes.
albopictus in this work and it is presumed that these sensilla may function as contact chemoreceptor
in addition to mechanotactile function.
Temporal resolution in olfaction: Stimulus integration time of lobster chemoreceptor
DALLAS -- Haloperidol is, perhaps surprisingly to many, the drug of choice for nausea and vomiting caused by stimulation of the chemoreceptor
trigger zone--the No.
Chemotherapeutic agents trigger the process of emesis through activation of multiple neurotransmitter receptors in the vomiting center of the brain, chemoreceptor
trigger zone, and gastrointestinal tract (1).
Correlated evolution of prey chemical discrimination with foraging, lingual morphology and vomeronasal chemoreceptor
abundance in lizards.
