Parotid Gland
Apocrine glands are the less numerous type of perspiration-producing gland found mainly in the pubic and axillary regions. These glands are larger than eccrine glands and produce a thicker secretion that can be odorless but may develop a distinct odor when bacteria on the skin break down the secretion.
The word "Sjogren's" is pronounced "SHOW-grins." It is a chronic autoimmune disorder that mainly affects the salivary and lacrimal glands.
The main differences between the posterior and anterior pituitary glands are in their functions and hormone secretion. The posterior pituitary mainly stores and releases hormones produced by the hypothalamus, such as oxytocin and vasopressin, while the anterior pituitary produces and releases its own hormones, including growth hormone, thyroid-stimulating hormone, and adrenocorticotropic hormone.
The sebaceous glands, which release the oily substance called sebum that mainly causes acne. :)
The salivary glands in the digestive system can become inflamed in a condition called mumps. Mumps is caused by a viral infection and is characterized by swelling and pain in the affected glands, typically the parotid glands located near the ears. It can cause fever, headache, and difficulty chewing or swallowing.
Most glands do not have ducts. The ones that do are called exocrine glands; mainly these just are sweat glands, oils glands, digestive glands, and sexaul reproducitive glands.
Lactation is the secretion of milk from a mammals mammary glands. Originating from the nipples, lactation is used mainly in breastfeeding newborn babies.
Saliva is secreted from three different salivary glands. Saliva is mostly water with minute quantities of enzymes and ions. Saliva is very important to make ingested food easy to swallow.
The stomach produces acid to help break down and digest food. The acid is mainly produced by glands in the lining of the stomach.
Salivary glands are located in the mouth region. They are situated on each side of the face, beneath the tongue, and near the jawbone. These glands produce saliva, which helps with digestion and keeps the mouth moist.
Apocrine sweat glands are inactive until they are stimulated by hormonal changes in puberty. Apocrine sweat glands are mainly thought to function as olfactory pheromones, chemicals important in attracting a potential mate. The stimulus for the secretion of apocrine sweat glands is adrenaline, which is a hormone carried in the blood.According to another suggestion, apocrine sweat glands were developed in the earliest period of human evolution via natural selection as a means of defence from predators as a warning signal, and that is why these glands are activated in the moments of emotional or physical stress.
Here is my BS answer followed by a good lead: Rats over time have survived mainly as decomposers much like worms and flies. They eat our waste and then break it down further, but that must require an extraordinarily wide range of foods that are edible to them. Overly developed saliva glands allowed certain rate to proliferate more and over time became intrinsic to their being.
