A chemical synapse normally transmits information:
From: Neuromuscular JunctionCorrect answer: A. Chemical synapses are functionally polarized, with transmitter release from the presynaptic cell.Which energy system can rapidly regenerate ATP during the first seconds of intense muscle activity?
From: Skeletal Muscle PhysiologyCorrect answer: E. Phosphocreatine rapidly donates phosphate to ADP to regenerate ATP during brief intense activity.Cardiac muscle cells are electrically coupled mainly through:
From: Smooth & Cardiac Muscle PhysiologyCorrect answer: B. Gap junctions permit ionic current to spread between cardiac myocytes.The undershoot following a neuronal action potential occurs because:
From: Synaptic TransmissionCorrect answer: B. K+ channels close slowly, so continued K+ efflux transiently hyperpolarizes the membrane.
