Explanation:
Smooth muscle tissue is composed of smooth muscle cells that are spindle-shaped with a single nucleus. Smooth muscles line the walls of hollow organs such as urinary bladder, uterus, stomach, intestines but also arteries and veins and the tracts of the respiratory, and reproductive systems. Smooth muscles are under involuntary control, meaning that their contraction is unconscious.

Explanation:
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x, y) parallel to the (x, y)-plane. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.
