Q

Endocrine system

A

Cooperate with the nervous system to maintain homeostasis by regulating body activities. This is accomplished by endocrine hormones that affect various processes throughout the body, such as growth, metabolism, and secretions from other organs.

Is composed of the ductless glands, and other structures that secrete hormones into the bloodstream.

The endocrine system, and the nervous system cooperate to maintain homeostasis.

Q

Endocrine glands

A

Are ductless glands, which secrete hormones, special chemical substances, into the blood that are carried to another part of the body, where they exert specific physiologic effects.
endocrine glands (for example, the thyroid and pituitary glands) are ductless, so they secrete their hormones into the bloodstream

Endocrine glands are ductless and produce and secrete hormones into the blood or lymph nodes.

Respond to hormones produced by the pituitary gland, it is named the “master gland.”

Q

Hormones

A

The chemical secretions of endocrine glands.

Special chemical substance

Hormones are either proteins or steroids. Most hormones in the human body are proteins with the exception of the sex hormones, and those from the adrenal cortex, which are steroids, (a special group of lipids.)

Chemical substances produced in an organ that initiate or regulate the activity of another organ are called hormones

Q

The target cell concept

A

Explains how only certain cells of specific organs are affected by a specific hormone.
The hormone recognizes the target tissue through receptors (the site that interacts with the hormone ), so the hormones act only on cells that have receptors specific for that hormone. The shape of the receptor determines which hormone can react with it.

Q

Diuretic

A

Means increasing urine excretion or the amount of urine. It also means an agent that promotes a urine excretion.

Some common caffeinated drinks, (tea, coffee, soda) and even water can act as diuretics. Physicians also prescribe diuretic drugs to rid the body of excess fluid in patients with edema.
Diuretics increase urination.

Diuretic=more urination
Antidiuretic hormone (ADH)
=less urine excretion

            Absence of ADH
            = much urine excretion

Antidiuretic

A

Pertaining to the suppression of urine excretion

Hormone acts against a diuretic. it acts in the kidneys to reabsorb water from the urine, producing concentrated urine.
Absence of this hormone produces diuresis, passage of large amounts of dilute urine.
Antidiuretic hormone causes a decrease in the amount of water lost in urination.

Q

Regulatory and inhibitory hormones stimulate, or inhibit the adenohypophysis

A

Hypothalamic regulatory and inhibitory hormones act on the adenohypophysis to either stimulate or inhibit the secretion of its hormones. When the adenohypophysis, secretes hormones, they travel through the bloodstream and bring about changes in other organs, often another endocrine gland. Note that the control from the hypothalamus to the adenohypophysis is hormonal, whereas the control of the neurohypophysis—as mentioned earlier— is through nervous stimulation.

Are lactiferous glands in the female breast that are the target organs of oxytocin and PRL. Many problems associated with the breast are not a result of hormones. However, hormones may be related to breast disorders, for example, inappropriate lactation (nipple discharge.)

The memory glands secrete, a cloud of fluid called colostrum during the first few days, after a female gives birth.

Changes in the memory glands, prepare the breast of a pregnant, female for lactogenesis, the production of milk

Are the two glands of the female breast that secrete milk. The female breasts are accessory organs of the reproductive system.
The breasts are located anterior to the chest muscles and each breast contains 15 to 20 lobes of the glandular tissue that radiate around the nipple.

Q

Lactation

A

Is the secretion or ejecting of milk. Milk ejection is a normal reflex in a lactating woman and is elicited by tactile stimulation of the nipple (such as nursing by the infant). impulses from the nipple to the hypothalamus stimulate the release of oxytocin by the pituitary gland, which brings about contractions that inject the milk from the breast. If a lactating mother stops nursing, milk production usually ceases within a few days.

Q

Interrelationships of hypothalamus, neurohypophysis, and breast

A

Suckling by the infant stimulates nerve endings at the nipple. Impulses are carried to the hypothalamus, which causes the neurohypophysis to secrete oxytocin into the bloodstream. The oxytocin is carried to the breast, where it causes milk to be expressed into the ducts. Milk begins to flow within 30 seconds to 1 minute after a baby begins to suckle.

Q

Pineal gland

A

That exact functions have not been established, but there is evidence that it secretes the hormone melatonin.

Pineal gland usually begins to diminish around the age of seven years. If degeneration does not occur, the production of melatonin remains high, and puberty may be delayed in girls. This indicates that melatonin may inhibit the activities of the ovaries.

98
Q

Melatonin

A

Is secreted by the pineal gland. In addition to a regulatory function in sexual development, effects of melatonin may increase the sleepiness – wakefulness cycle and mood and may cause a decrease in skin pigmentation.

So named because its release is stimulated by darkness

99
Q

Homeostasis

A

Stability of the internal environment of the body

Stability in the normal body state

Strict regulation of hormonal secretion is important to maintain homeostasis

100
Q

Three different methods to regulate

A

1) direct nervous stimulation
2) secretion of hormones in response to other hormones
3) negative feedback mechanism

101
Q

Tropic hormones

A

Cause secretion of other hormones. For example, thyrotropin TSH from the anterior pituitary gland causes the thyroid gland to secrete the thyroid hormones

102
Q

Example of a negative feedback system

A

The interaction between two important pancreatic hormones and the concentration of glucose in the blood is an example
In negative feedback, a gland is sensitive to the concentration of a substance that is it regulates.
Page 561

103
Q

Two important hormones,
glucagon and insulin. Page561

A

The islets of Langerhans secrete two important hormones which regulate each other through negative feedback, (a decreased function in response to stimulus)

104
Q

Carbohydrates

Page 561

A

Food contains carbohydrates, which are broken down into glucose for energy

After eating a meal that contains carbohydrates, hyperglycemia results.

Then the hormone insulin is secreted that promotes the uptake and utilization of glucose. As the level of glucose drops, glucagon is secreted to prevent blood sugar from dropping too low between meals, and the cycle begins again.
The action of insulin and glucagon are opposite or antagonistic to each other, one, causing the blood glucose to increase the other, causing it to decrease.

105
Q

Glucose

A

The type of sugar found in blood

106
Q

Elevated blood glucose levels

A

Stimulate the secretion of insulin from the pancreas

107
Q

As blood glucose levels decrease, the stimulus or insulin secretion also decreases

108
Q

Hypoglycemia

A

An abnormally low concentration of glucose in the blood

Is a less than normal amount of glucose in the blood. It is caused by administration of too much insulin, excessive secretion of insulin by the pancreas, or dietary deficiency. An individual with hypoglycemia usually experiences weakness, headache, hunger, visual disturbances, and anxiety. If untreated, hypoglycemia can lead to coma and death.

109
Q

Hyperglycemia

A

And increase the amount of sugar in the blood

Is a greater than normal amount of glucose in the blood

Means a greater than normal level of glucose in the blood. Diabetics are urge to control. Blood glucose levels to significantly reduce complications of uncontrolled diabetes.

Causes serious fluid and electrolyte imbalances, ultimately resulting in the classic symptoms of diabetes: polyphagia, polyuria, and polydipsia.

110
Q

Diabetes mellitus DM

A

Insufficient Insulin activity, and the resulting of hyperglycemia

Insufficient, secretion or resistance to insulin

DM is caused by a deficiency or a complete lack of insulin secretion or resistance to insulin by target cells

When used alone, the term diabetes generally refers to diabetes mellitus, but one should be aware that the term diabetes means excessive excretion of urine, and diabetes insipidus, for example, is so named because of its classic symptoms, not because of its relationship to DM.
Broad classifications of DM are type 1, type 2, gestational, and other types. Type 1 diabetes mellitus is genetically determined and results in absolute insulin deficiency. Individuals with this particular gene produce little or no insulin and are classified as having type 1 diabetes mellitus. This disease was previously called insulin-dependent diabetes mellitus IDDM.

Is primarily a result of resistant to Insulin or a deficiency or complete lack of insulin secretion by the insulin producing cells of the pancreas. Without insulin, glucose builds up in the blood and hyperglycemia results.

111

Frequently encountered breast disorders include fibrocystic, disease, breast, cancer, and benign tumors.

A

Is a disorder characterized by single or multiple benign cysts of the breast. The cysts must be considered potentially malignant until diagnostic test indicate otherwise; there after, the breasts should be observed carefully for change. The cysts often occur as a result of cyclic breast changes that accompany the menstrual cycle.

206
Q

A

A number of breast tumors (for example, fibroadenoma, which is a non-tender encapsulated tumor) are benign and can be differentiated from cancerous tumors by mammography and biopsy.
Excluding skin cancer, breast cancer has been the most common malignancy among women in the United States for years. The cause of breast cancer is still unknown, but early detection and improved treatment have contributed to a decrease in mortality rates. Breast cancer in females is still a major cause of cancer death. Breast cancer in males is rare.

207
Q

Is a term that means breast cancer. Ductal carcinoma in situ DCIS is any of a large group of carcinomas confined to the lactiferous duct where it is formed

209
Q

Blood glucose entering the cells

A

The presence and function of insulin are essential to facilitate blood glucose entering the cells. Under normal conditions, insulin is released into the bloodstream in small increments, with increased release when food is ingested. Hypoglycemia occurs with an overdose of insulin to treat diabetes, insufficient, intake of food, or excessive exercise.

210
Q

Treatment of hypoglycemia

A

May consist of a glucose paste inside the cheap, administration of glucose (dextrose), such as that, found an orange juice, or intravenously if the person is unconscious.

211
Q

Excessive secretion of insulin

A

Strict attention to diet is important for patients with hypoglycemia caused by excessive secretion of insulin

212
Q

The goal of treating diabetes mellitus

A

Is to maintain a balance of the body’s insulin and glucose.
Type 1 diabetes is controlled by administration of insulin, proper diet, and exercise. Insulin is administered by injecting on a regular basis, (subcutaneous injection or via an insulin pump).

213
Q

Insulin pump

A

Is a portable battery operated insulin delivery device that is used by some diabetics. It can be programmed to deliver doses of insulin according to the body’s needs.
The insulin pump is worn externally. It delivers precise doses of rapid acting insulin to closely match your body’s needs. Additional insulin can be delivered on demand before an unusually large meal or to correct a high blood sugar.

214
Q

Hypophysectomy

A

Is surgical removal or destruction of the hypophysis (pituitary).

Surgical removal of the pituitary gland may be performed to excise a pituitary tumor or to slow the growth and spread of endocrine dependent malignant tumors. It is done only if other treatment fails to destroy all pituitary tissue.

215
Q

Glucose lowering agent

A

Insulin is a glucose, lowering agent. Type two diabetes is controlled by diet, exercise, oral agents, and sometimes insulin.

216
Q

Hypopituitarism

A

Because the most common cause of hypopituitarism is pituitary tumor, treatment consist of surgery or radiation to remove the tumor, followed by administration of deficiency hormones.

Certain types of pituitary tumors can cause over production of GH, and the treatment of choice is surgery to remove the tumor. Irradiation of the tumor and drugs may also be indicated.

217
Q

Treatment of hyperthyroidism

A

Is destruction of large amounts of the thyroid tissue by either surgery, or radioactive materials, or the use of anti-thyroid drugs to block the production of thyroid hormones

Is seeking or prolapsed breasts.

225
Q

mastopexy also called a breast lift

A

Surgical fixation of the breasts
Is perform to correct a pendulous breast

226
Q

Metastases

A

The extent and location of metastases determines the therapeutic strategy in breast cancer. For breast cancer with distant metastases, non-surgical treatment (chemotherapy, hormone therapy, and sometimes radiation) may be prescribed. For women with breast cancer at a stage for which surgery is recommended, follow up after the surgery with chemotherapy, radiation, hormone therapy, or targeted therapy may be prescribed.

227
Q

Lumpectomy

A

Excision of a lump in the breast

Is surgical excision of a tumor that is known to be or suspected of being a cancer
Excision of the lung with removal of varying amounts of tissue is often the treatment of choice and breast cancer. The amount of extra tissue removed ranges from a small amount of surrounding healthy tissue to the entire breast.

228
Q
