A gland is an organ in an animal's body that synthesizes a substance for release such as hormones, often into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland). Gland - Types of gland. Humans have a large variety of glands, from the pituitary gland in the brain, to sweat glands over the body's skin that release perspiration to regulate the body's temperature. Other well known glands include the adrenal glands, the prostate gland, the thyroid gland, the ...

Exocrine gland refers to glands that secrete their products via a duct. This is as opposed to endocrine glands that release their products directly into the circulatory system via the capillary network. Typical exocrine glands include sweat glands, salivary glands, mammary glands and many glands of the digestive system. Exocrine gland - Types. Exocrine glands are named apocrine, holocrine, or merocrine based on how their product is secreted. Apocrine glands - a portion of the sec ...

In certain animals, including European badgers, foxes, and wolves, the violet gland or supracaudal gland is an important gland located in the tail. It is used for scent marking and contributes to the strong odor of foxes. Although it secretes a mixture of volatile terpenes similar to those produced by violets (hence the name), the chemicals are produced in much greater quantity than in flowers and the resulting strong smell can be quite unpleasant. Like many other mammalian secretion glands, the violet gland cons ...

Every gland is formed by an ingrowth from an epithelial surface. This ingrowth may from the beginning possess a tubular structure, but in other instances glands may start as a solid column of cells which subsequently becomes tubulated. As growth proceeds, the column of cells may divide or give off offshoots, in which case a compound gland is formed. In many glands the number of branches is limited, in others (salivary, pancreas) a very large structure is finally formed by repeated growth and sub-division. As a rule the branches do not unite ...

The parathyroid glands are small endocrine glands in the neck, usually located within the thyroid gland, which produce parathyroid hormone. Most often there are four parathyroid glands but have been known to number six or eight. Parathyroid gland - Anatomy. The parathyroid glands are four small glands located on the posterior (closer to the back) surface of the thyroid gland. They distinguish themselves from the thyroid gland histologically as they contain two types of cells- parathyroid chief cells and oxy ...

In the anatomy of the male human body, the bulbourethral glands (or Cowper's glands) are two small, rounded, and somewhat lobulated bodies, of a yellow color, about the size of peas, placed behind and lateral to the membranous portion of the urethra, between the two layers of the fascia of the urogenital diaphragm. They lie close above the bulb, and are enclosed by the transverse fibers of the Sphincter urethrae membranaceae. Their existence is said to be ...

The pineal gland or epiphysis, is a small endocrine gland. It is located near the center of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join. It is also referred to as the pineal body. Pineal gland - Location. The pineal gland is a small, pea-sized, (8 mm in humans) reddish-gray body located above the superior colliculus and behind and beneath the stria medullaris, between the laterally positioned thalamic bodies. It is part of the epithalam ...

The Bartholin's glands (also called Bartholin glands or greater vestibular glands) are two glands located slightly below and to the left and right of the opening of the vagina in women. They secrete mucus to provide lubrication, especially when the woman is sexually aroused, thus facilitating sexual activity. They were first described in the 17th century, by the Danish anatomist Caspar Bartholin the Younger (1655-1738). Some sources mistakenly ascribe their discovery to his grandfather, theologian and anatomist Caspar Bartholin the Elder (1585 - 1629). Bartho ...

In mammals, the adrenal glands (also known as suprarenal glands or colloquially as kidney hats) are the triangle-shaped endocrine glands that sit atop the kidneys; their name indicates that position (ad, "near" or "at" + renes, "kidneys"). They are chiefly responsible for regulating the stress response through the synthesis of corticosteroids and catecholamines, including cortisol and adrenaline. Adrenal gland - Overview.

The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea that sits in the small, bony cavity (sella turcica) at the base of the brain. Its posterior lobe is connected to a part of the brain called the hypothalamus via the infundibulum (or stalk), giving rise to the tuberoinfundibular pathway. The posterior lobe is thus derived from neural ectoderm while the anterior lobe is derived from oral ectoderm. The anterior pituitary lobe receives releasing hormones from the hypothalamus via a portal vein system. ...

The endocrine system is a control system of ductless endocrine glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distant organs.

Sweating (also called perspiration or sometimes transpiration) is the loss of a watery fluid, consisting mainly of sodium chloride and urea in solution, that is secreted by the sweat glands in the skin of mammals. Sweat also consist of the chemicals or odorants 2-methylphenol and 4-methyphenol. In humans, sweating is primarily a means of temperature regulation. Evaporation of sweat from the skin surface has a cooling effect due to the latent heat of evaporation of water. Hence, in hot weather, or when the individual's mu ...

The word Merkaba (Hebrew: מרכבה "chariot, tank", derived from the ancient Hebrew consonantal root r-k-b with general meaning "to ride (an animal, in a chariot)") is used in the Bible (Ezekiel 1:4-26) to refer to the throne-chariot of god, the four-wheeled vehicle driven by four Cherubim, each of which has four wings and four faces (of a man, lion, ox, and eagle). In medieval Judaism, the beginning of the book of Ezekiel was regarded as the most mystical passage in the Bible, and its study was discouraged, except by mature individuals with an extensive groun ...

Cherry eye is the term used to refer to canine nictitans gland prolapse, a common eye condition in various dog breeds where the gland of the third eyelid prolapses and becomes visible. This condition usually must be corrected, mostly through surgery, because the gland produces some of the eye's tears. Older methods of cherry eye correction involved simply removing the gland, but it is a last-resort procedure today (complemented with a lifetime of eyedrops if performed), as the gland's purpose was unknown then. Modern methods of cherry ...

The anatomy of a bee's mouth is complex. The mandibles (jaws) are suspended from the head at the sides of the mouth. They are used in handling objects, manipulating pollen and in contact with other bees. Above the mandibles is the mandibular gland which secretes a substance once thought to be used to soften wax. It's now known that the mandibular gland of the queen secretes pheromones responsible for maintenance of the social organization of the colony. The mandibular glands are almost completely reduced in the drone. The front of the ...
