  Ductless Glands - LoveToKnow 1911
It is absent as a distinct gland in the Acrania and Cyclostomata.
Adrenal Glands The adrenal glands or suprarenal capsules are two conical bodies, flattened from before backward, resting on the upper poles of the kidneys close to the sides of the vertebral column; each has an anterior and posterior surface and a concave base which is in contact with the kidney.
The median part of the gland is developed from a tube which grows down in the middle line from the junction of the buccal and pharyngeal parts of the tongue, between the first and second branchial arches.

 The Mystery of the Ductless Glands, by A Student
The ductless glands are often spoken of as the endocrine glands or the hormone producing glands.
The ductless glands are of more than particular interest to the students of the occult for they may be termed in a certain sense "the seven roses" upon the cross of the body, and are intimately connected with the occult development of humanity.
The principal ductless glands are the pineal, pituitary, thyroid, thymus, spleen, and the two adrenals.

 Ductless gland - Wikipedia, the free encyclopedia
Ductless glands are glands that secrete their product directly onto a surface rather than through a duct.
Examples are the goblet cells in the epithelial surface of the digestive, respiratory, urinary and reproductive systems.
Many endocrine glands are also ductless glands, as they secrete the hormones they produce directly into the blood or lymph system so it will be circulated to the entire body.

 Oil gland - Wikipedia, the free encyclopedia
An oil gland is a sebaceous (or sebiferous) gland that secretes sebaceous matter.
Ductless glands situated internally are not true oil glands, however, fishermen will often cleanse bottom-feeding fish such as carp by removing an internal organ (which is said to be "the oil gland").
Removing "the oil gland" from a carp prior to cooking removes some of the accumulated substances, some of which may also be toxic or harmful to a person who eats fish.

But, so far, there was no hint as to the actual structure within the pancreas upon which the antidiabetic influence of the gland depends and it is primarily to the anatomists, Laguesse and Diamare, that we owe the hypothesis that this must be the collection of cells, named after their discoverer, the isles of Langerhans.
As this anatomical work was in progress, the potent action of extracts of the suprarenal gland on the blood pressure and other physiological functions was discovered, in 1894, by Oliver and Schafer, thus adding strong support to the hypothesis that the ductless glands function by producing internal secretions.
No success attended these attempts partly, we believe, because the antidiabetic principle was destroyed, either during the preparation of the extracts or by the action of the digestice juices, and partly, because of imperfect knowledge of the clinical course of the disease, particularly with regard to the relationship of diet to it.

The results of thyroid extirpation had been complicated by the failure to recognize and leave intact the tiny parathyroid glands in the midst of the thyroid tissue; the effects of removing the pituitary gland were confused by the effects of surgical damage to the hypothalamic region of the brain.
After the discovery that preparations of thyroid gland taken by mouth were of benefit in myxoedema and cretinism, thyroid extract began to be given for many and varied conditions, an extracts of other ductless glands were prescribed with an enthusiasm that outran knowledge.
In view of the apparent interrelation of many of the glands of internal secretion it is quite probable that certain of the symptoms known to accompany hypophyseal disease may be consequent upon a secondary change in other glands which follow the primary change of the hypophysis.

Before beginning these lessons on the ductless glands it would be well for us to briefly review the origin and constitution of man. There is nothing in the universe other than pure spirit, and there never has been; but there are two forms or poles of spirit.
What the scientists do not know yet is that the ductless glands primarily do not belong to the physical body at all, but are adjuncts to the vital body, set apart and [PAGE 4071] crystallized to the necessary density in order that they may perform certain special kinds of work.

Parathyroid hormone (PTH) is released from the parathyroid gland (behind the thyroid) and is used to maintain homeostatic levels of calcium in the blood.
It is not clear how the parathyroid gland 'knows' this, but calcium is a very significant ion for all cells and it is very conceivable that the parathyroid gland itself does the detection.
Often a particular gland (a structure we can dissect from the body in one piece) can make several hormones, but that is only because certain cells that make one hormone have come together in the same area with other cells that make another hormone.

The endocrine system is comprised of endocrine glands, which produce and release hormones, and their target cells.
A hormone is a specific chemical substance (molecule) secreted into the circulation by an endocrine gland (ductless gland), and carried in the blood to another area of the body, where it elicits a biological response from selected target cells.
Endocrine glands regulate many processes in the body; therefore, careful regulation of hormonal output is critical.
