The adrenal glands are comprised of two parts--the cortex and medulla--that produce hormones (chemicals messengers that regulate body functions). The medulla, or inner part of the adrenal glands, produces the hormones norepinephrine and epinephrine, which regulate the fight or flight response in the body, the body's reaction to stressful events.
One cun = width of the thumb, in the middle, at the crease. or. One cun = the distance between the distal and proximal inter-phalangeal joints of the 3rd (middle) finger. One and 1/2 cun (1.5) = width of the two forefingers. Three cun = combined breadth of the four fingers, at the level of the pinky finger's first joint above the palm of the hand.
The distance formula is used to determine the distance, d, between two points. If the coordinates of the two points are (x 1, y 1) and (x 2, y 2), the distance equals the square root of x 2 â x 1 squared + y 2 â y 1 squared. The distance formula is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points.
