Cards

Term
Hypothalamus
Definition
portion of the brain that regulates the production of multiple hormones
Term
The Anterior Pituitary
Definition
regulated by the hypothalamus, releases 7 hormones
Term
Posterior Pituitary
Definition
stores Oxytocin (OT) and Antidiuretic Hormone (ADH)
Term
Thyroid Gland
Definition
regulates basal metabolic rate (BMR), oxygen consumption and cellular metabolism
Term
Parathyroid
Definition
regulates the homeostasis of calcium (increases) and phosphate (decreases) levels in the blood.
Term
Pancreas
Definition
both exocrine and endocrine, posterior and inferior to the stomach. comprised of the Islets of Langerhans
Term
Pancreas
Definition
alpha cells- secrete glucagon
beta cells- secrete insulin
Term
Adrenal Glands
Definition
lie atop each kidney, consist of an outer cortex and inner medulla
Term
Adrenal Glands
Definition
mineralcorticoids, such as aldosterone
glucocorticoids, such as cortisol
Term
Ovaries
Definition
paired oval bodies, produce sex hormones
Term
Testes
Definition
external glands, produce sex hormones
Term
Pineal Gland
Definition
attached to the roof of the third ventricle of the brain, secretes melatonin (biological clock)
Term
Thymus
Definition
produces hormones related to immunity; retrosternal
Term
Human Growth Hormone (hGH)
Definition
skeletal muscles and bone growth
Term
Prolactin (PRL)
Definition
milk secretion from the mammaries
Term
Adrenocorticotropic Hormone (ACTH)
Definition
glucocorticoids
Term
Melanocyte-stimulating Hormone (MSH)
Definition
darkens skin
Term
Thyroid-stimulating Hormone (TSH)
Definition
thyroid stimulation
Term
Follice-stimulating Hormone (FSH)
Definition
sperm in males and oocytes in females
Term
Luteinizing Hormone (LH)
Definition
stimulates ovulation, progesterone and estrogen in females
Term
Oxytocin (OT)
Definition
uterine contraction and milk letdown
Term
Antidiuretic Hormone (ADH)
Definition
water reabsorption by the kidneys and arteriole vasoconstriction
Term
Glucagon
Definition
increases blood glucose level; secretion controlled by blood glucose levels
Term
Insulin
Definition
decreases blood glucose level; secretion controlled by blood glucose levels
Term
Mineralcorticoid
Definition
increases Na and water reabsorption, decrease K reabsorption; regulate Na and K levels in the blood
Term
Glucocorticoid
Definition
promotes metabolism of proteins and fats; serves as antiinflammatory agent; suppresses immune response
Term
Thymus
Definition
produces lymphocytes
Term
Pineal Gland
Definition
releases melatonin
Term
Thyroid Gland
Definition
releases TSH/T3/T4 and thyroxin
Term
Pancreas
Definition
releases digestive enzymes
Term
Thyroid Gland
Definition
located below the larynx; bi-lobed
Term
Hypothalamus
Definition
located in the diencephalon
Term
Lipid-Soluble Hormones
Definition
include steroid hormones, thyroid hormones and nitric oxide
Term
Water-Soluble Hormones
Definition
includes amines, proteins, peptides and eicosanoids
Term
Endocrine System
Definition
releases chemical messengers to all cells in the body; only those with specific receptors bind with them
Term
Nervous System
Definition
sends impulses to specific sets of cells
Term
Nervous System
Definition
controls homeostasis by releasing neurotransmitters to stimulate production of certain hormones
Term
Hormones
Definition
released on demand in short bursts; only affect target cells
Term
Target Cells
Definition
the principal action site of a hormone; contain specific receptors that bind with one or more hormones
