Saltatory conduction is - Study guides, Class notes & Summaries

How Neurons Integrate Information- Through dendritic spines, a neuron can establish more than 50,000 connections to other neurons - Nerve impulses traveling from other neurons bombard the receiving neuron with all manner of inputs (excitatory and inhibitory) - The cell body, located between the dendritic tree and its axon, can receive inputs from many other neurons Saltatory ConductionMyelin and Node of Ranvier Node of RanvierPart of an axon that is not covered by myelin Tiny gaps in the myeli...

ADVANCED PLACEMENT (AP) BIOLOGY: Nervous System 83 Questions Correctly Answered | 100% Rated Action potentials move down myelinated axons via saltatory conduction. This is because __________. Possible Answers: they jump from the middle of the gaps to the middle of the myelin sheaths additional impulses boost their speed periodically they jump from gap to gap in between the myelin sheaths they speed up dramatically in areas with more myelin wrapping, depending on the thickness of the sheath C...

How do local anesthetics block the nerve impulse from reaching the brain? By permanently depolarizing the nerve cell membrane By overwhelming influx of fluoride ions By blocking sodium channels, thereby preventing nerve cell depolarization and impulse propagation By causing massive neurotransmitter release without uptake. By blocking sodium channels, thereby preventing nerve cell depolarization and impulse propagation How do local anesthetics stop working? By diffusion of the lo...

1. Question: Describe the recent finds on the "Nature-Nurture Controversy." How do evolutionary theory (evolutionary biology and evolutionary psychology) and the study of genetics fit in to this discussion? What are the implications for the biopsychologist? And finally, is there a controversy at all? 2. Question: Describe the process of action potential conduction and neurotransmission from one neuron to another, both electrically (including saltatory conduction) and chemically. Describe how ...

MileDown MCAT Biology Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the role of the myelin sheath in neural transmission? The myelin sheath insulates axons, allowing for faster transmission of electrical impulses along the neuron through saltatory conduction. Describe the process of endocytosis in cellular transport. Endocytosis is a process where the cell membrane engulfs extracellular material, forming a vesicle that brings the material into the ce...
