The tissue of the heart is composed of three major layers:
The outer most is the Epicardium. "Epi" refers to "outside"
The inner most layer is the Endocardium. "Endo" refering to "inside"
The layer in between is called the Myocardium. It is the thickest layer and is composed of cardiac muscle. Thus its name, as "myo" is a prefix meaning "muscle".

The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
The innermost part of something refers to the most central or deepest section. It is the core or nucleus of an object or concept.
This refers to the area around the plasma membrane. In a bacterium, the area between the plasma membrane and the the bacterial cell wall.

The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
Membrane irritability refers to the ability of a cell membrane to respond to stimuli by generating an action potential, while membrane conductivity refers to the ease with which ions can pass through the cell membrane. Irritability is more related to the excitability of the membrane, while conductivity is related to the flow of ions across the membrane.
osmosis refers to the movement of water across a membrane. Diffusion refers to everything else tending towards equal concentration.
The resting potential of a cell is the membrane potential when the cell is at rest, typically around -70 millivolts. Membrane potential refers to the difference in electrical charge across the cell membrane. Resting potential is a type of membrane potential that is maintained when the cell is not actively sending signals.

That probably refers to the layer of roofing felt(paper) that lies between the roof sheathing(plywood) and the shingles..a fallen limb could tear thru that "membrane" and rain could become an issue
The term is 'Valency'
