Endocrine System VII

The Endocrine System

QuestionAnswer
This organ produces hormones that stimulates activity in ovaries and testes Anterior Pituitary
This organ produces hormones that causes uterus to contract and kidneys to reabsorb water. Posterior Pituitary
This organ produces hormones that regulates metabolism and lowers blood calcium concentrations. Thyroid
This organ produces hormones that increases blood calcium concentration Parathyroid
This organ produces hormones that increases sodium and water reabsorption in kidneys Adrenal Cortex
This organ produces hormones that increase blood glucose levels and heart rate Adrenal Medulla
This organ produces hormones that decreases or increases blood sugar concentration Pancreas
This organ produces hormones that promote female secondary sex characteristics and thickens endometrial lining Ovaries
This organ produces hormones that promote male secondary sex characteristics and spermatogenesis Testes
What does the hormone oxytocin do? Causes uterus contraction.
What does the hormone calcitonin do? Lowers blood calcium levels
What does the hormone glucagon do? Increases blood sugar concentration
What does the hormone vasopressin do? Causes kidney to reabsorb water
What does the hormone prolactin do? Causes mile secretion
What does the hormone ACTH do? Stimulates the adrenal cortex
What does the hormone LH do? Stimulates activity in ovary (release of ovum) and production of testosterone
What does the hormone FSH do? Stimulates activity in ovaries and testes
What does the parathyroid hormone do? Increases blood calcium concentration
What does the hormone aldosterone do? Increase sodium and water reabsorption in kidneys
What does the hormone epinephrine norepinephrine do Increase blood glucose level and heart rate. They give you a quick boost of energy. Fight or Flight response.
This system uses neurons to send nerve impulses. The Nervous System
This system secretes hormones The endocrine system
What does the hormone TSH do? Is stimulates the thyroid to secrete thyroxine
These are 4 pea-shaped organs that rest on your thyroid Parathyroid
Islets of Langerhans are a cluster of cells produced from what organ? Pancrease
Name the two adrenal glands? Adrenal cortex and the adrenal medulla
This hormone is released by the adrenal cortex. It targets the liver to promote the release of glucose Glucocorticoids
This hormone is released by the adrenal cortex. It targets the kidneys and promotes the retention of water. Mineralocorticoids
This gland is referred to as the emergency gland. Adrenal Medulla
Where are the adrenal glands located? One on each kidney
Hormones only affect these types of cells in our body? Target cells
How do hormones work if they are a steroid (Lipid soluble) If a hormone is a steroid (lipid soluble) it will diffuse across the membrane of a target cell. It then binds to a receptor protein in the nucleus and activates a specific gene contained in the DNA, which in turn make proteins.
How do hormones work if they are a protein, peptide, or amine and cannot penetrate the target cell membrane? The hormone binds to a receptor protein on the cell membrane of the target cell. This protein stimulates the production of a second messenger call cyclic AMP (cAMP). the cAMP molecule triggers various enzymes, leading to specific cellular changes.
How about mnemonics? When you think of the pituitary, think of GATOR pit. With that said, what are the hormones secreted by the pituitary? Growth Hormone ACTH Thyroid-Stimulating hormone Oxytocin R, for antiduiRetic hormone (or vasopressin)
This organ secretes neurosecretory hormones They hypothalamus
