Short-latency excitation of phrenic motor output mediated by non-NMDA receptors
1Department of Physiology, University of Kentucky, Lexington 40536-0084, USA.
Abstract:
This study tested the hypothesis that the short-latency excitation of the phrenic motor output elicited by superior laryngeal nerve (SLN) stimulation requires non-NMDA receptor-mediated neurotransmission in the region of the dorsal respiratory group (DRG) of the adult cat. Injection of the non-NMDA receptor antagonist NBQX into the DRG severely attenuated or abolished the short-latency excitation, indicating that the short-latency excitation requires non-NMDA receptor-mediated neurotransmission within the DRG.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...
Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
Motor Unit Stimulation
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...
