Endocrine Flashcards
“Master gland” of the body that tells other glands to release their respective hormones
-On the sela turcica on the sphenoid bone
Pituitary gland
Functions in controlling metabolism and regulating body functions like breathing and heart rate
-Located in the neck
Thyroid gland
Regulate calcium levels
-Located on the posterior surface of the thyroid
Parathyroid glands
Create hormones that control heart rate, blood pressure, immune system function, and other both functions
-Located on the superior surface of each kidney
Adrenal glands
Functions in regulating blood glucose levels (Islets of Langerhans specifically) secreting digestive enzymes
-Located on the abdominal wall posterior to the stomach
Pancreas
Functions in immune system
-Located behind the sternum
Thymus
Produce melatonin (function in regulating sleep/ wake cycle)
-Located in the brain
Pineal glands
Metabolic disorder in which carbohydrates are not broken down into sugars properly because of a lack of insulin
-Can lead to blindness, carbuncles and ulcers of the feet and legs, renal failure and cardiac disorders
-Type ___: insulin dependent diabetes (pancreas does not make insulin)
-Type ___: non insulin dependent diabetes(pancreas does not make enough insulin and the body develops a level of resistance to insulin and the body can’t keep sugar levels regulated
Diabetes mellitus
Hyperfunction of the pituitary gland after ossification has completed
-Chronic disease causing an overproduction of human growth hormone (most adult cases are benign tumor in pituitary gland)
-Causes elongation and enlargement of the bones of the extremities and the head
-Appears slowly over time
Acromegaly
An excessive growth of unossified bones due to overproduction of human growth hormones
-Begins in childhood
Giantism (gigantism)
Stunted growth caused by an insufficient production of human growth hormone (associated with pituitary gland)
Dwarfism
An inability of the kidneys to conserve water because of an inability of the pituitary gland to properly release antidiuretic hormone
-Caused by damage to the pituitary gland (surgery, infection, tumors, injuries, or kidney complications)
Diabetes insipidus
Under active thyroid gland
Hypothyroidism
Congenital hypothyroidism resulting in developmental disabilities
-Occurs in infants and children
-Causes mental and physical developmental issues and lowered metabolism
Cretinism
Non congenital hypothyroidism
-Usually the result of an iodine deficiency
-Usually refers to hypothyroidism in adults but can refer to children as well
-Associated with waxy and thick skin, edema, slow speech, and mental apathy
Myxedema
