mechanism of the body is of secondary importance.
It is quite credible that the nerves are only the
keys or instruments which are played upon by
more dominant agents in the form of the endocrine
glands. In comparison with men, women are said
to be peculiarly nervous. Would it not be more
accurate to say that on account of the undoubted
instability of their internal glandular equipment
women are peculiarly endocrinous? Whether this
theory be true or not there is no doubt whatever
that the gynecologist accomplishes more accurate
results if he estimates synthroid levothyroxine buy synthroid his nervous patients from an
endocrinological rather than from a purely neuro-
logical viewpoint.
THE OVARIES.
The synthroid price second part of this paper deals synthroid online primarily
with the histogenesis of the secreting cells of the
ovary and is synthroid mcg presented with the hope of pointing
out some practical synthroid cheap lessons that may be gained
thereby. It has been asserted synthroid tablets and is more or less
generally believed that the ovary is a compound
secreting gland with at least two systems of secret-
ing cĀ°lls, analogous in that respect to the hypophysis
and adrenals. generic synthroid Thus the hypophysis as a whole is
composed of two very distinct parts which differ
in their histogenesis, their effects on the body under
the influence of disease and in the specific action
of their respective internal secretions. The pos-
terior lobe is nervous, or ectodermic in origin.
Early disease of the lobe produces a dwarfish in-
dividual. Extract of the lobe, commonly called
pituitrin, exerts an influence on the autonomic
nervous system and is efficacious in the treatment
of atonic conditions of the smooth muscles synthroid mg of the
bladder, intestines, and uterus. The anterior lobe
on the other hand, is glandular, hence mesodermal
in origin. Early disease produces giantism, while
extracts of the lobe affect chiefly the sexual system.
In like manner the adrenals are made up of two
separate tissue structures, which are so distinct in
their anatomical and physiological characteristics
that they may properly be regarded as different
organs, that happen to have developed in juxtapo-
sition. The order synthroid online medulla 'has a common ectodermal
origin with the sympathetic nervous system, from
which it becomes separated during the process of
embryonic evolution. The medullary cells are not
only contained within the cortex of the adrenal
body but are scattered along the sympathetic buy cheap synthroid nerves
or ganglia in isolated bodies. The intimate recipro-
cal association of the sympathetic and medullary
systems we have already mentioned in our discus-
sion of the influence on the emotions of adrenalin,
the specific secretion of the medullary cells.
The cortical cells of the adrenals, on the cost of synthroid other
hand, are mesodermal in origin and are intimately
related to the cells that compose the ovary. They
spring from the same peritoneal layer from which
the ovaries take their origin. The cortical cells where to buy synthroid
resemble the cells of the corpus luteum order synthroid so closely
that attempts have been made to establish some sort
of identity between them. As in the case with the
adrenal medulla, the cortical cells are not confined synthroid buy online
to the adrenal body, but are synthroid cost found scattered along
the track traveled by the ovary in its descent into
the pelvis. Physiologically the internal secretory
function purchase synthroid online is sexual, though comparatively little is
known of its action.
Reasoning by analogy to the hypophysis and ad-
renals some have purchase synthroid made the claim that the ovary is
also a double functionating organ, the two sources
of secretion being ascribed to the corpus luteum or
follicle apparatus on the one hand and the ovarian
stroma on the other. A study of the histogenesis
and development of the cells that compose the
ovarian tissue dispels the notion of a close analogy
between the ovary and the other two glands men-
tioned, for it can be shown from an embryological
viewpoint that the ovary is a single homogeneous
organ and that the differences that exist between the
various cell elements are due to a process of differ-
entiation during the development of cells that have a
common origin. A detailed description of the his-
tological development of the ovary can only be re-
ferred to in briefest outline.
The ovaries are developed in the peritoneum and
from the peritoneum. Their primary growth is
characterized by a thickening in the peritoneal mem-
brane due to a localized multiplication and change
in form of the peritoneal cells. These cells con-
stitute what is known as the germinal epithelium.
The ovaries, at first simple thickened ridges in the
peritoneum, attain their fusiform price of synthroid contour by a
downgrowth of the germinal epithelium, into the
subperitoneal connective tissue.
The germinal epithelium possesses a wonderful
power of differentiation and growth. Owing to
the researches of Allen, Macllroy, Goodall, and
others it is now known that all the inherent cell
