In myelinated axons where are the voltage gated sodium channels concentrated?
In myelinated axons, the voltage gated sodium ions are located along the nodes of Ranvier, the exposed places between the myelin segments. The gates here, however, are not particularly more concentrated than on other un-myelinated axons. TRUE

Where do axon collaterals emerge on a myelinated nerve?
Axon collaterals emerge from the main axon at regular intervals called Nodes of Ranvier on a myelinated nerve. These points are where the myelin sheath is interrupted, allowing axon collaterals to branch off and communicate with other neurons or muscle fibers.
What does not belong nodes of ranvier myelin sheath cell body axon?
Cell body does not belong because the other options are all components of a nerve cell. Cell body (soma) is the main part of the neuron where the nucleus is located, while the nodes of Ranvier, myelin sheath, and axon are all structures found in the axon of a neuron.
If two line segments are congruent must be true?
If two line segments are congruent, it means they have the same length. This implies that both segments can be measured and found to be equal in distance from one endpoint to the other. Therefore, congruence in line segments indicates that they are identical in size, even if their positions or orientations differ in space.
How do the radial and planar nodes differ in terms of their spatial distribution within a system?
Radial nodes are spherical regions around the nucleus of an atom where the probability of finding an electron is zero. Planar nodes, on the other hand, are flat surfaces where the probability of finding an electron is also zero. Radial nodes are distributed spherically around the nucleus, while planar nodes are distributed in specific planes within the atom.
What are lines line segments and rays?
The three differ in their extent. Lines are infinite in both directions. Line segments are finite: they have two well defined end-points. Rays are finite in one direction, infinite in the other: it has one end-point and stretches to infinity in the other direction.
What is ratio of segments?
It is the length of one (or more) segments compared to the length of other segments.
Which chart types divides a single total into parts to illustrate how the segments differ from each other and the whole?
The chart types that divide a single total into parts to illustrate how the segments differ from each other and the whole are pie charts and stacked bar charts. Pie charts visually represent proportions of a whole, with each slice indicating the size of a segment relative to the total. Stacked bar charts display segments within bars, allowing for comparison of both individual parts and the overall total across different categories.
Which network topology do all nodes have independent connections to all other nodes?
Bus
How are the segments of a crayfish differ from thoses of earthworm?
As opposed to earthworms, arthropods (crayfish) segments often become fused. Therefore, certain parts of a crayfish that looks like one piece, was once multiple pieces before they became fused together, so some segments were actually once more than just that one segment. An earthworm on the other hand, is just as many segments as are seen, and always has been.
Is saltatory conduction made possible by large nerves fibers diphasic impulses myelin sheath or erratic transmission of nerve impulses?
Saltatory conduction is made possible by gaps in the myelin sheath (called nodes of Ranvier) along the axon, which allow for the action potential to "jump" from one node to the other, increasing conduction velocity.
