But the peripheral chemoreceptors
respond more rapidly to decreased or increased arterial oxygen partial pressure (PaO2), decreased or increased PaC[O.
Functional characterization of antennal contact chemoreceptors
in the cockroach, Periplaneta americana: an electrophysiological investigation.
These setae have the typical structure of chemoreceptors
On the other hand, in contrast to aortic denervation, sino-aortic denervation, as usually performed, also destroys carotid chemoreceptors
and results in hypoventilation, which by itself induces chronic hypoxia with its consequent chronic lowering of blood pressure (22,23).
This stability is achieved by the exquisite sensitivity of the chemoreceptor
system, typically assessed by measuring the change in minute ventilation as a patient rebreathes C[O.
Sensilla coeloconica are considered as hygrothermoreceptors or contact chemoreceptors
Peripheral feedback mechanisms (carotid chemoreceptors
, respiratory muscle receptors, and limb locomotor muscle group III-IV afferents) enhance the sympathetically mediated pressor response (29).
Neuronal information is transported via the autonomic nerve (especially the vagus) from chemoreceptors
in the internal visceral organs.
There are more than five sense receptors if we include enteroreceptors, such as proprioceptors (tension receptors) in muscles, tendons and joint capsules, or chemoreceptors
for detecting blood pH, C[O.
2] = 50 mm Hg), which may have stimulated central, peripheral, and intrapulmonary chemoreceptors
On the other hand, central command from higher brain centres and inputs from mechano- and chemoreceptors
in contracting muscles contribute to maintaining sympathetic activity (though to a lesser extent than during exercise) preventing faster HR decay (Carter et al.
The ToxT-dependent methyl-accepting chemoreceptors
AcfB and TcpI contribute to Vibrio cholerae intestinal colonization.
On an insect limb two main categories of sense organs can be found; mechanoreceptors and chemoreceptors
, where only the former type are thought to have influence on agile locomotion (Delcomyn, F.
Their topics include a natural history of sensor domains in bacterial signaling systems, sensing ligands by periplasmic sensing histidine kinases with sensory pas domains, bacterial chemoreceptors
as membrane-spanning allosteric enzymes, metal-dependent and metal responsive regulatory systems, and thiol-based sensory factors.
One of the beetle species that did not return has such long mandibles that the rootworm blood never even reached its mouth, indicating that chemoreceptors
in the beetle's external mouthparts--rather than rootworm blood--made them decide against eating the rootworms.
