gland

(gland )

[L. glans, stem gland-, acorn]

1. An epithelial tissue that is specialized for the manufacture and export of particular molecules. Glands can be unicellular or multicellular. The multicellular glands are classified according to their architectures, i.e., ducted or ductless. The cells of ductless glands secrete specific molecules into the adjacent interstitial space (paracrine glands) or into the bloodstream (endocrine glands). The cells of ducted glands (exocrine glands) secrete into a cylindrical sac (tubular glands) or into a flask-shaped sac (alveolar glands). The ducted glands are further divided into those in which there is only a single sac (simple tubular glands or simple alveolar glands) and those in which the sacs are connected by branching ducts (branched or compound glands). Glands can also be classified according to the secretory mechanisms of their cells. The most common secretory mechanism is merocrine, in which secretion-filled intracellular vesicles release their contents by fusing with the cell membrane. Other secretory mechanisms include holocrine (in which the gland cell membrane disintegrates to release its secretion), apocrine (in which the ends of the gland cells pinch off, carrying the secretion), and direct active transport of particular molecules across the gland cell membrane. Gland cells and their intertwined vascular beds can be controlled by autonomic innervation and by hormones from other glands.
2. A lymph node.

accessory gland

1. An additional (usually smaller) gland that secretes the same substances as a primary gland.
2. A gland secreting substances that enhance the function of another gland or organ. In the male reproductive tract, for example, the prostate, which secretes fluids that improve the viability of sperm, is an accessory gland to the testis.

ADRENAL GLANDS

EMBRYOLOGY
Each adrenal gland is a two-part organ composed of an outer cortex and an inner medulla. The cortex arises in the embryo from a region of the mesoderm that also gives rise to the gonads. The medulla arises from ectoderm, which also gives rise to the sympathetic nervous system (SNS).

ANATOMY
The entire gland is enclosed in a capsule of tough connective tissue from which trabeculae extend into the cortex. The cortex consists of cells arranged into three zones: the outer zona glomerulosa, the middle zona fasciculata, and the inner zona reticularis. The cells are arranged in cords. The medulla consists of chromaffin cells arranged in groups or in anastomosing cords. The two adrenal glands are retroperitoneal, each embedded in perirenal fat above its respective kidney. In an adult, the average weight of an adrenal gland is 5 g (range between 4 and 14 g).

PHYSIOLOGY
The adrenal medulla synthesizes and stores three catecholamines: dopamine, norepinephrine, and epinephrine. The chief effects of dopamine are the dilation of systemic arteries, increased cardiac output, and increased flow of blood to the kidneys. The primary action of norepinephrine is constriction of the arterioles and venules, resulting in increased resistance to blood flow, elevated blood pressure, and slowing of the heart.

The adrenal medulla is controlled by the SNS system and functions in conjunction with it. It is intimately related to adjustments of the body in response to stress and emotional changes. Anticipatory states tend to bring about the release of norepinephrine. More intense emotional reactions, esp. those in response to extreme stress, tend to increase the secretion of both norepinephrine and epinephrine; epinephrine is important in mobilizing the physiological changes that occur in the “fight or flight” response to emergency situations.

The cortex synthesizes three groups of steroid hormones from cholesterol. These are 1) glucocorticoids (cortisol, corticosterone), which regulate the metabolism of organic nutrients and have an anti-inflammatory effect; 2) mineralocorticoids (aldosterone, dehydroepiandrosterone), which affect metabolism of the electrolytes sodium and potassium; and 3) androgens and estrogens (estradiol), which contribute to body changes at puberty.
SEE: aldosterone; SEE: cortisol; SEE: steroid

PATHOLOGY
Hypersecretion of adrenal cortical hormones results in Cushing syndrome. Hypersecretion of aldosterone results in aldosteronism (a surgically correctable form of hypertension). Adrenocortical insufficiency may be acute or chronic: acute insufficiency of adrenal hormones produces circulatory shock; chronic insufficiency results in Addison disease.

endocrine gland

One of two broad categories of glands, the exocrine glands being the complementary category. Endocrine glands, e.g., the thyroid gland, are ductless glands that secrete macromolecules, called hormones, directly into the bloodstream, and such glands are richly supplied by blood capillaries. The endocrine glands include the suprarenals, parathyroids, pineal, pituitary, and the thyroid. Major clusters of endocrine tissue are also found in the gastrointestinal tract, hypothalamus, ovaries, pancreas, testes, and the placenta. In addition, chromaffin and other neuroendocrine cells are found individually and in small clusters throughout the body. SEE: exocrine gland;


ENDOCRINE SYSTEM ; SEE TABLE: Principal Endocrine Glands
The hormones produced by endocrine cells regulate the body's salt, water, mineral, and glucose levels; they adjust the body's metabolic balances, growth rates, and reproductive cycles; and they maintain the body's stress responses. Like exocrine and paracrine cells, endocrine cells are stimulated and inhibited by the autonomic nervous system; the activities of endocrine cells are also modulated by circulating hormones, esp. pituitary hormones. Both the neural and the hormonal signals to the endocrine system are ultimately regulated by the hypothalamus of the brain, which is the integration center for the body's visceral homeostasis.
SEE: hormone

Endocrine health disorders usually result from the production of either too much or too little of a hormone.

Any of four small endocrine glands about 6 mm long by 3 to 4 mm broad on the back of and at the lower edge of the thyroid gland or embedded within it. These glands secrete parathormone.

ABNORMALITIES
A deficiency of parathormone results in hypoparathyroidism, which results in neuromuscular hyperexcitability manifested by carpopedal spasm, wheezing, muscle cramps, urinary frequency, mood changes, and lassitude. Blood calcium falls and blood phosphorus rises. Other symptoms include blurring of vision caused by cataracts, poorly formed teeth if onset was in childhood, maldevelopment of hair and nails, and dry and scaly skin.

An excess of parathormone results in hyperparathyroidism which results in a rise in blood calcium and fall in blood phosphorus. Calcium is removed from bones, resulting in increased fragility. Muscular weakness, reduced muscular tone, and general neuromuscular hypoexcitability occur. Osteitis fibrosa cystica is associated with hyperplasia and resulting hypersecretion of the parathyroids.

PITUITARY GLAND Hormones secreted by the anterior and posterior pituitary gland, along with target organs ; SEE: adenohypophysis; SEE: anterior pituitary


FUNCTION
The pituitary is an endocrine gland secreting a number of hormones that regulate many bodily processes including growth, reproduction, and other metabolic activities. It is often referred to as the master gland of the body.

Hormones are secreted from the following lobes: Intermediate lobe: In cold-blooded animals, intermedin is secreted, influencing the activity of pigment cells (chromatophores) of fishes, amphibians, and reptiles. In warm-blooded animals, no effects are known.

Anterior lobe: Secretions here are the somatotropic, or growth hormone (STH or GH), which regulates cell division and protein synthesis for growth; adrenocorticotropic hormone (ACTH), which regulates functional activity of the adrenal cortex; thyrotropic hormone (TTH or TSH), which regulates functional activity of the thyroid gland; and prolactin (lactogenic hormone), which induces secretion of milk in the adult female. The gonadotropic hormones are: in women, the follicle-stimulating hormone (FSH), which stimulates development of ovarian follicles and their secretion of estrogen; in men FSH stimulates spermatogenesis in the testes. In women, luteinizing hormone (LH) (also called interstitial cell-stimulation hormone [ICSH]) stimulates ovulation and formation of the corpus luteum and its secretion of estrogen and progesterone. In men, LH stimulates testosterone secretion.

Posterior lobe: Hormones are secreted by the neurosecretory cells of the hypothalamus and pass through fibers of the supraopticohypophyseal tracts in the infundibular stalk to the neurohypophysis, where they are stored. The secretions are oxytocin, which acts specifically on smooth muscle of the uterus, increasing tone and contractility, and antidiuretic hormone (ADH) (also called vasopressin), which increases reabsorption of water by the kidney tubules. In large amounts, ADH also causes vasoconstriction.

DISORDERS
Hypersecretion of anterior lobe causes gigantism, acromegaly, and pituitary basophilism (Cushing disease). Hyposecretion of anterior lobe causes dwarfism, pituitary cachexia (Simmonds disease), Sheehan syndrome, acromicria, eunuchoidism, or hypogonadism. Posterior lobe deficiency or hypothalamic lesion causes diabetes insipidus. Anterior and posterior lobe deficiency and hypothalamic lesion cause Fröhlich syndrome (adiposogenital dystrophy) and pituitary obesity.

preputial gland

A modified sebaceous gland located on the distal aspect of the penis, near the glans. The secretion of this gland is a component of smegma.

prostate gland

The gland in the male that surrounds the neck of the bladder and the urethra. It is partly glandular, with ducts opening into the prostatic portion of the urethra, and partly muscular. It secretes a thin, opalescent, slightly alkaline fluid that forms part of the semen. The prostate consists of a median lobe and two lateral lobes measuring about 2 × 4 × 3 cm and weighing about 20 g; it is enclosed in a fibrous capsule containing smooth muscle fiber in its inner layer. The nerve supply is from the inferior hypogastric plexus.

pyloric gland

A gastric gland in the pyloric region of the stomach.

racemose gland

SEE: Acinar gland.

salivary gland

Any of the glands near the oral cavity that secrete saliva. The major glands are paired and include the parotid, the sublingual, and the submandibular. There are numerous minor salivary glands in the oral cavity, named according to their locations: lingual, sublingual, palatal, buccal, labial, and glossopharyngeal.


SALIVARY GLANDS
Salivary secretion is under nervous control, reflexly initiated by mechanical, chemical, or radiant stimuli acting on taste buds in the mouth, olfactory receptors, or the eyes. Secretion may also be due to conditioned reflexes as when one thinks about food or hears a dinner bell. The nerve supply of the salivary glands is from the facial and glossopharyngeal nerves, which increase secretion, and from the sympathetic nerves, which decrease secretion. The blood supply is from branches of the external carotid artery.

sebaceous gland

An oil-secreting gland of the skin. The glands are simple or branched alveolar glands, most of which open into hair follicles. They are holocrine glands whose secretion arises from the disintegration of cells filling the alveoli. Some aberrant glands are found in the cheeks or lips of the oral cavity.
SEE: Fordyce disease

seromucous gland

A mixed serous and mucous gland.

serous gland

An exocrine gland with a relatively watery secretion, isotonic with blood plasma, and containing enzymes, glycoproteins, lysozymes, and bactericides. Serous glands are most common in the gastrointestinal tract, esp. in the salivary glands.

sex gland

An ovary or a testis.

simple gland

SEE: sweat glands for illus

suprarenal gland

SEE: Adrenal gland.

sweat gland

Any of the simple, coiled, tubular glands found on all body surfaces except the margin of the lips, glans penis, and inner surface of the prepuce. The coiled secreting portion lies in the corium or subcutaneous portion of skin; the secretory duct follows a straight or oblique course through the dermis but becomes spiral in passing through the epidermis to its opening, a sweat pore. Most sweat glands are merocrine; those of the axilla, areola, mammary gland, labia majora, and circumanal region are apocrine. Sweat glands are most numerous on the palms of the hands and soles of the feet.

thymus gland

SEE: thymus

thyroid gland

A large endocrine gland located in the center of the base of the neck. The gland is composed of two lobes, one on each side of the trachea, and an isthmus of tissue connecting the lower two thirds of each lobe. The isthmus is usually located at the level of the second to third tracheal rings. The whole gland is surrounded by a thin fibrous capsule attached in back to the cricoid cartilage and the first few tracheal rings. The lobes of the thyroid lie under the sternothyroid and sternohyoid muscles. The thyroid is filled with capillary networks (supplied by the superior and inferior thyroid arteries) that surround the many spherical units (follicles) packed inside the gland. Thyroid follicles consist of a ring of follicular cells surrounding a space filled with a clear colloid (a mixture of thyroglobulin proteins and iodine), from which the thyroid hormones (thyroxine and related molecules) are synthesized. These hormones regulate the rate of cellular metabolism throughout the body. All the steps in synthesizing and releasing thyroid hormones are stimulated by thyroid-stimulating hormone secreted by the pituitary gland. Another class of thyroid cells, the parafollicular or C cells, is found outside the follicles; C cells secrete calcitonin, a calcium-lowering hormone.
