Adv Exp Med Biol
. 2009 Jun;
648:83-8.
PMID: 19536468
Carotid body type-I cells respond to acute hypoxia with membrane depolarization and calcium-dependent neurotransmitter release. The inhibition of a TASK-like background potassium channels plays a key role in initiating this...

. 1998 Jun;
786(1-2):47-54.
PMID: 9554949
The petrosal ganglion innervates carotid body chemoreceptors through the carotid (sinus) nerve. These primary sensory neurons are activated by transmitters released from receptor (glomus) cells, acetylcholine (ACh) having been proposed...
