Functions
The section "Areas of Electrical Coupling" reflects the circumstances of earliest discovery of gap junctions and their function in allowing the transmission electrical impulses among cells at levels that elicit responses from their neighboring cells. The transmission of a nerve impulse and the contraction of muscle are relatively easily detected and quantified experimentally. "Areas of Electrical Coupling" also touches upon the retinal gap junctions which could be seen as specialist nerve cells. Many new functions for gap junctions have been uncovered since those early years.

Famous quotes containing the word functions:
“One of the most highly valued functions of used parents these days is to be the villains of their children’s lives, the people the child blames for any shortcomings or disappointments. But if your identity comes from your parents’ failings, then you remain forever a member of the child generation, stuck and unable to move on to an adulthood in which you identify yourself in terms of what you do, not what has been done to you.”
—Frank Pittman (20th century)
“Those things which now most engage the attention of men, as politics and the daily routine, are, it is true, vital functions of human society, but should be unconsciously performed, like the corresponding functions of the physical body.”
—Henry David Thoreau (1817–1862)
“In today’s world parents find themselves at the mercy of a society which imposes pressures and priorities that allow neither time nor place for meaningful activities and relations between children and adults, which downgrade the role of parents and the functions of parenthood, and which prevent the parent from doing things he wants to do as a guide, friend, and companion to his children.”
—Urie Bronfenbrenner (b. 1917)
