In: Anatomy and Physiology
Fill in Table 1 with the resting membrane potentials reported in different cell types, and different organisms (ie squid, frog, etc) – Discuss the findings – is the resting membrane potential different in different tissue types? Is the resting membrane potential different in the same tissue but from different animals? Discuss why there are differences and what the likely reason for it is physiologically.
