Some species can spin silk from glands in their mouth.

In prostate cancer, the cells of these prostate glands mutate into cancer cells.

The most common location for neuroblastoma to originate (i.e., the primary tumor) is on the adrenal glands.

In an orb web weaving spider, you can find seven types of silk glands, and what I have depicted here in this picture, let's start at the one o'clock position, there's tubuliform silk glands, which are used to make the outer silk of an egg sac.

They are of two kinds (1) simple tubular glands resembling those of the pyloric end of the stomach, but with short ducts.

If the imbalance is taking place in the pituitary glands, growth disorders are possible and will require treatment of a growth hormone.

It most frequently originates in one of the adrenal glands, but can also develop in nerve tissues in the neck, chest, abdomen, or pelvis.

Surgery tends to be done only when just one of the thyroid glands is affected (unilateral disease) however, following surgery, the remaining gland may become over active.

The infection itself is usually cured with a 10 day course of antibiotics, but it may take a few weeks for tonsils and swollen glands to return to normal.

Many chemical mediators are involved, including cortisol and adrenalin from the adrenal glands, other hormones and neurotransmitters (such as serotonin and noradrenalin), and responses from the autonomic and immune systems.

So if you ever have the opportunity to dissect an orb web weaving spider, and I hope you do, what you would find is a bounty of beautiful, translucent silk glands.

The name is an acronym deriving from some of the main features Polyneuropathy (peripheral nerve damage), Organomegaly (abnormal enlargement of organs), Endocrinopathy (damage to hormone producing glands) or Edema, M protein (an abnormal immunoglobulin) and Skin abnormalities (including hyperpigmentation and hypertrichosis).

Skin conductance, also known as galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR), or skin conductance level (SCL), is a method of measuring the electrical conductance of the skin, which varies depending on the state of sweat glands in the skin.
