56
Parathyroid Glands
four small glands with the sole purpose of secreting parathyroid hormone to regulate the body's calcium level. Though located near each other, the parathyroid glands are unrelated to the thyroid gland.
57
Thyroid Gland
a butterfly-shaped gland located in front of the trachea in the neck. It is comprised of two halves, known as lobes, attached by a band of thyroid tissue called the isthmus.
The thyroid's main role in the endocrine system is to regulate the body's metabolism. Metabolism describes all the processes involved in the body's use of nutrients, including the rate at which they are used.
58
Pineal Gland
Located near the center of the brain, the pineal gland is a very small organ shaped like a pinecone (which is where it gets its name).
The pineal gland secretes a single hormone: melatonin. Melatonin helps control your circadian rhythm. The circadian rhythm is the body's internal clock characterized by sleep-wake cycles. Darkness and daylight help dictate your circadian rhythm. Melatonin stays elevated for most of the night, and light exposure stops the release of melatonin.
59
Thymus Gland
located behind the sternum and between the lungs.
The thymus secretes thymosin, an instrumental hormone in the production and maturation of T-lymphocytes, or T cells. T cells are a specific type of white blood cell that circulates in the body, scanning for cellular abnormalities and foreign invaders. T cells can kill cells infected with viruses and bacteria, eradicate cancer cells, and help the body protect itself against autoimmunity (when the immune system turns against itself).
60
Adrenal Glands
- two of them sit on top of the kidneys
- primary functions of the adrenal glands is to control the body's electrolyte levels
- comprised of two distinct structures. The outer part is called the adrenal cortex. The inner region is known as the adrenal medulla.
61
Adrenal Cortex Hormones: Cortisol
Helps regulate metabolism and also has anti-inflammatory action
62
Adrenal Cortex Hormones: Aldosterone
Keeps the electrolyte balance within normal limits
63
Adrenal Cortex Hormones: Androgens
Releases small amounts of male and female sex hormones
64
Adrenal Medulla Hormones: Epinephrine (adrenaline)
Helps you deal with physical and emotional stress
65
Adrenal Medulla Hormones: Norepinephrine
Works with epinephrine in responding to stress
66
Pituitary Gland
the endocrine system's "master gland" because its hormones send signals to other endocrine glands to stimulate or inhibit their own hormone production
- consists of an anterior lobe and a posterior lobe
67
Anterior Lobe Hormones: Adrenocorticotropic hormone (ACTH)
Stimulates the adrenal glands to produce hormones
68
Anterior Lobe Hormones: Follicle-stimulating hormone (FSH)
Ensures normal functioning of the ovaries and testes
69
Anterior Lobe Hormones: Growth hormone (GH)
Aids the growth of healthy bone and muscle mass
70
Anterior Lobe Hormones: Luteinizing hormone (LH)
Works with FSH to ensure normal functioning of the ovaries and testes
71
Anterior Lobe Hormones: Prolactin
Stimulates production of breast milk after childbirth
72
Anterior Lobe Hormones: Thyroid-stimulating hormone (TSH)
Stimulates the thyroid gland to produce hormones
73
Anterior Lobe Hormones: Melanocyte-stimulating hormone (MSH)
Increases the production of melanin, causing darkening of the skin pigmentation
74
Posterior Lobe Hormones: Antidiuretic hormone (ADH)
Helps control blood pressure by prompting the kidneys to reduce the amount of water excreted
75
Posterior Lobe Hormones: Oxytocin
Stimulates contraction of the uterus during childbirth and stimulates breast milk production
76
Hypothalamus (brain)
Heart rate and blood pressure
Body temperature
Fluid and electrolyte balance, thirst
Appetite and weight
Glandular secretions of the stomach and intestines
Sleep-wake cycle
Sex drive
77
Pancreas
belongs to both the endocrine and digestive systems, with most of its cells (more than 90%) working on the digestive side. However, the pancreas performs the vital duty of producing hormones, most notably insulin, to maintain the balance of blood glucose (sugar) and salt in the body. Without this balance, your body is susceptible to serious complications, such as diabetes.
78
Hormones of the Pancreas: Insulin
Moves glucose from the blood into the cells for energy. This drops blood glucose levels.
79
Hormones of the Pancreas: Glucagon
Works in the opposite way of insulin by stimulating the cells to release glucose. This raises blood glucose levels.
80
Ovaries
produce and release two groups of sex hormones: progesterone and estrogen. Progesterone and estrogen are necessary to prepare the uterus for pregnancy, and the hypothalamus triggers their release.
81
Testes
secrete testosterone, which is necessary for proper physical development in boys. During puberty, testosterone is involved in the development of male secondary sex characteristics, including the maturation of male sex organs, growth of facial and body hair, lowering of the voice, and increase in height and muscle mass.
82
Gigantism
Abnormal growth of the entire body caused by excessive secretion of growth hormone before puberty
Contrast with acromegaly
83
Diabetes insipidus
An imbalance of fluids in the body, leading to extreme thirst and frequent urination that is caused by an insufficient production of the antidiuretic hormone ADH or by the inability of the kidneys to respond appropriately to this hormone
Not related to diabetes mellitus
84
Syndrome of inappropriate antidiuretic hormone (SIADH)
Bloating and water retention that can dilute the blood, causing electrolyte imbalances, particularly hyponatremia, caused by overproduction of the anti-diuretic hormone ADH
85
Pinealoma
A tumor of the pineal gland that can disrupt the production of melatonin, causing insomnia
86
Myxedema
