In which vessel can you feel your pulse - artery or vein? Why?

You’re most likely just feeling your pulse in your abdominal aorta. It runs from your heart, down the center of your chest, and into your abdomen. It’s normal to feel blood pumping through this large artery from time to time.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
