The cardiac activity could be moderated by the autonomous neural system. asked Feb 15, 2018 in Class XI Biology by nikita74 (-1,017 points)Why are gap junctions a vital part of the intercellular connection of cardiac muscles? A. Gap junctions contract when stimulated, strengthening the force of cardiac cell contraction. B. Gap junctions form strong intercellular connections. C. Gap junctions allow calcium to enter the cell, triggering calcium release from the SR.Cell - Cell - Gap junctions: These junctions allow communication between adjacent cells via the passage of small molecules directly from the cytoplasm of one cell to that of another. Molecules that can pass between cells coupled by gap junctions include inorganic salts, sugars, amino acids, nucleotides, and vitamins but not large molecules such as proteins or nucleic acids.why are gap junctions a vital part of the intercellular connection of cardiac muscles? asked Jan 3 in Other by manish56 (-34,887 points) -1 vote. 1 answer.

Gap junctions develop when a set of six proteins (connexins) in the plasma membrane arrange themselves in an elongated donut-like configuration - a connexon. When the connexon's pores ("doughnut holes") in adjacent animal cells align, a channel between the two cells forms. Gap junctions are particularly important in cardiac muscle.Why are gap junctions a vital part of the intercellular connection of cardiac muscles? gap junctions allow action potentials to spread to connected cells. If cardiac muscle is deprived of its normal blood supply, damage would primarily result from _____. decreased delivery of oxygen.why are gap junctions a vital part of the intercellular connection of cardiac muscles? asked Jan 3 in Other by manish56 (-34,887 points) 0 votes. 1 answer.

Gap junctions allow action potentials to spread to connected cells. 149. Which of the following is NOT part of the intrinsic conduction system of the heart? atrioventricular (AV) valve 150. The parietal pericardium _____.Why are gap junctions a vital part of the intercellular connection of cardiac muscles? a) Gap junctions allow calcium to enter the cell, triggering calcium release from the SR. b) Gap junctions allow action potentials to spread to connected cells. c) Gap junctions contract when stimulated, strengthening the force of cardiac cell contraction.Why are gap junctions a vital part of the intercellular connection of cardiac muscles? Gap junctions are a form of electrical synapse that allow action potentials to spread to connected cells. This property allows the signal to spread efficiently through the heart.Cardiac Cell to Another Across Gap Junctions Cardiac muscle cells also have chemical synapses, but the sympathetic and parasympathetic branches of the auto-nomic nervous system (see Chapter 15) use these synap-Cellular Physiology of Skeletal, Cardiac, and Smooth Muscle / 9 231 ses to modulate, rather than to initiate, cardiac muscle function.
Why are gap junctions a vital part of the intercellular connection of cardiac muscles?
A) gap junction forms intercellular connection
B) Gap junction permit action potentials to unfold to connected cells
C) gap junction contract when stimulated, strengthening the force of cardiac cellular contraction
D) Gap junction permit calcium to go into the cell, triggering calcium unlock from SR
