According to the Gasser classification scheme, which type of nerve fiber has the largest diameter, the most myelination and the fastest conduction velocity?

The ability of the cell to respond to a stimulus is called:

Using information from the Autonomic Nervous System lecture, Match the following descriptions with the appropriate branch of the Peripheral Nervous System. Figures 6-43, 6-45, and Table 6-10 in the 13th edition of the Vander Physiology textbook may help.

The normal resting potential of cell membrane in nerve cell is about:

Na+ channels are [a] because they allow [b] ions into the cell depolarizing the membrane and driving it [c] the the threshold (firing) potential. Cl- channels are [d] because they allow [e] ions into the cell making it [f] for the membrane to depolarize. K+ channels are [g] because they allow [h] ions out of the cell making it [i] for the membrane to depolarize.

Match each description in the left column with the best response from the right column.

The movement of the water across the cell membrane from an area of higher to lower concentration is known as:

Where is the higher concentration of pottasium (K+) found?

If the membrane potential becomes more negative than  -70 mV (resting), it is known as:

How does the neuron code for the strength of stimuli?
