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".
If you are asking about the membrane that covers the heart, it is the pericardium. If you are asking about the thin membrane that covers the myocardium, it is the epicardium.
pericardium
Epicardium.
This refers to the area around the plasma membrane. In a bacterium, the area between the plasma membrane and the the bacterial cell wall.
thumb: the thick short innermost digit of the forelimb
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.
osmosis refers to the movement of water across a membrane. Diffusion refers to everything else tending towards equal concentration.
Resting membrane potential
Endosymbiosis refers to the engulfment of a prokaryotic cell that developed into an organelle, whereas invagination refers to the membrane folding in on itself and forming membranous organelles.
The term is 'Valency'
prokaryotic
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
Fluid refers for the frequent lateral movement of phospholipids within the membrane. Mosaic refers to the collage of intrinsic proteins that stud the membrane.
The term protoplast refers to the spherical shape assumed by Gram-positive bacteria. Spheroplast refers to the spherical shape assumed by Gram-negative bacteria. The difference is essentially the presence of a single membrane, in the case of the protoplast, and the two membranes (inner and outer) of the Gram-negative spheroplasts. It is also possible to generate a gram-negative protoplast by the removal of the outer membrane. Thus, in essence, protoplast refers to a bacterial sphere that is bounded by a single membrane and spheroplast refers to a sphere that is bounded by two membranes
Selective permeability refers to the fact that the plasma membrane can choose which molecules to let in or out of the cell.
