Integrative Signaling Of Mitochondria, Trpa1 And Trpv1 In Vagal Neurons, Katherine Stanford

USF Tampa Graduate Theses and Dissertations

Sensory nerves detect conditions in the external and internal environment and permit behavioral and physiological responses to maintain homeostasis and ensure survival. As such, sensory nerves detect a wide variety of stimuli including heat, touch, pH, and vibration. The precise nature of these responses is dependent upon the initiating stimulus and site of activation. Potentially threatening stimuli (noxious heat, cellular damage, chemical irritants) activate nociceptive sensory nerves through the gating of ion channels expressed at sensory nerve terminals, thereby evoking defensive reflexes such as cough, watering eyes and limb withdrawal as well as sensations of pain or discomfort. While these …
