Nerve and Muscle Physiology — Flashcards

In muscle contraction, after the muscle cell is depolarized, the action potential travels down the _____ and to the dihydropyridine receptor

Mitochondrial diseases mostly affect _____ and muscles, which are both highly aerobic

When the membrane potential is _____ mv the activation and inactivation gate of Na+ channel is open

In muscle hypertrophy, the _____ isoform of myosin heavy chain is replaced by the beta isoform (alpha/beta)

Resting membrane potential of a _____ muscle is -20 to -65 mV

During ocular motility, an increased flow of innervation to the contracting muscle is accompanied by the decreased flow of innervation to the relaxing antagonist muscle, is known as _____ law of reciprocal innervation

The Ca2+-calmodulin complex upregulates _____, which phosphorylates myosin and contracts smooth muscle.

Slow twitch muscle fibers perform more _____ due to increased mitochondria

Resting membrane potential of a _____ muscle is -90 mV

Rabies virus binds to nicotinic ACh receptors in the _____-synaptic membrane of the neuromuscular junction
