- The structure of sensory and motor neuronarrow_forwardDifference between impulse conduction in a myelinated nerve fibre and unmyelinated nerve fibre.arrow_forwardNerve transmission and communication with other neurons. DI it restores the membrane potential the chemical that talks between one neuron and the other neuron the point between the neuron and the muscle transmits impulse to dendrite it carries receptors on its surface it produces the neurotransmitter 1.

- summary of the whole process of action potentialarrow_forwardWhen a presynaptic neuron fires action potentialsarrow_forwardAn influx of positive sodium ions causes opening of the activation gates of voltage regulated sodium channels resulting in a further influx of positive sodium ions, and thus the initial stages of an action potential are regulated by ______ feedback.arrow_forward
- An influx of positive sodium ions eventually causes closing of the inactivation gates of voltage regulated sodium channels, stopping the influx of positive sodium ions, and thus the final stages of an action potential are regulated by _____ feedback.arrow_forwardIn the PNS, neuron cell bodies are located in ______________ and surrounded by neuroglial cells called ______________ cells.arrow_forward“All-or-none” response in impulse conductionmeans thatarrow_forward
- The speed of action potential propagation and synaptic transmissiondecreases with aging. List possible explanations.arrow_forwardIf action potential propagation from one neuron to another neuron requires ACh release, what event at the synaptic cleft explains the need for action potentials to arrive at a high rate before the post-synaptic membrane achieves threshold? the lack of sodium voltage gated channels on the post-synaptic membrane O the rapid breakdown of ACh by ACHE at the synaptic cleft the slow release of ACh by the synaptic vessicles the slow movement of sodium through chemical gates Previous Next MacBook Airarrow_forwardThe nervous system, the major anatomical and functional subdivisions. Three functional properties found in all neurons; define the three most basic functional categories of neurons List the six types of cells that aid neuronsarrow_forward
