Can anyone tell me what is difference between Morphology and Anatomy

Morphology initially refers to the descriptive science  studying the shape and visual appearance of the external structure of an animal, plant or organ. The morphology is thus distinguished at the origin of the anatomy, which is interested in the internal structure.

Explanation:

Morphology is the study of external (physical ) features of living organisms

while Anatomy is the study of the internal features of living organisms

Explanation:

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.
