Some scientists have estimated that there are some fifty thousand nerve
fibers going to the pituitary. Imagine this many wires going from this
great glandular transistor to assist in keeping the constant flow of the
many chemical messengers to the other parts of the body. This piece of
unobstrusive tissue is situated in one of the most protected areas of
the body. It sits in a bony depression called Sella Tursica, this means
Turkish saddle, because it looks like it we understand now that Secretion
from our glands are directly cast into our bloodstream and have the tendency
to renew the life and vigor of the body. In the absence of one of these
secretions the blood becomes unbalanced. The pituitary body produces secretions
of various kinds. One secretion has much to do with the regulation of
blood pressure, helps to renew veins that have been destroyed by a tubercular
condition.
Another secretion increases the fluid to the spinal cord the action
of which has already been explained. The same secretion increases the
action of the urine (system) and increases the secretion of the mammary
glands when they are active. A third secretion has a stimulating effect
on the tissue of the smooth muscles of the body, especially upon uterine
muscle, causing contraction and is essential to the muscles of the bladder
and reproductive organs. The pituitary also secrets a substance which
has much to do with the thyroid and adrenal glands and the regulation
of the growth of the skeleton.
