Endocrine Systems Review
Tropic- affect other glands and causes the secretion of other hormones.
Nontropic-Does not other glands, just the target gland
Negative feedback control systems- resists change in normal operating conditions.The mechanisms activated will restore conditions to their normal state.
Positive feedback control systems- move the controlled variable away from a steady state.
Pituitary- Master gland and controls most of the hormones in the body but is controlled by the hypothalamus.
Anterior pituitary- makes and stores hormones -> TSH, FSH, LH,PRL, GH, ACTH, MSH.
Posterior pituitary- made in hypothalamus ->ADH, Oxytocin
Hormones affecting blood sugar
Pancreas
-> Glucagon- Alpha cells of islets of langerhan- increases blood sugar levels
->Insulin- Beta cells of islets of langerhan- decreases blood sugar levels
Adrenal Gland
->Adrenal Medulla-produces epinephrine and norepinephrine- increases levels of blood in times of stress
->Adrenal Cortex- produces glucocorticoids- cortisol, which helps the blood recover from stress, increases blood sugar levels- and mineralcorticoids- associated with sodium absorptiona and water retention.
Hormones affecting metabolism
Thyroid Gland
-> Thyroxin(T4)- increases metabolism
-> Triiodothyronine(T3)-increases metabolism
->Calcitonin- decreases blood calcium by depositing it into the bones and is also being absorbed by intestines.
Parathyroid
->Parathyroid hormone-increases blood calcium- released from bones
->Human Growth hormone- affects all cells
Hormones affecting water balance
->ADH
-> Aldosterone
Hmmmm. I see a recap (very thorough), and above and beyond (additional info and diagrams), but not the "thoughts about the material" section.
ReplyDelete2/3 unless you can convince me otherwise.
