What is the function of the endocrine system? - answer Include
hormones and negative feedback loop. The functions include control of
the cellular respiration, cellular growth, cellular reproduction. Control of
the fluids in the body such as water amounts and balance of
electrolytes. Control the secretion of other hormones, behavior
patterns. Controls homeostasis.
What is the difference between endocrine and exocrine gland? - answer
Exocrine glands secrete substances into a ductal system to an epithelial
surface.
Endocrine glands secrete products directly into the bloodstream.
What are the important classification of the hormones and give
example? - answer Amino acids, Protein hormones, steroid hormones.
Amino acids: - answer Secreted by adrenal medulla: Epinephrine,
norepinephrine. Secreted by the posterior pituitary gland: oxytocin,
vasopressin.
,Protein hormones: - answer Insulin from the pancreas islets, gonad-
stimulating hormones, growth hormone, anterior pituitary gland.
Steroid hormones (lipids): - answer Cortisol from adrenal cortex.
Estrogen and testosterone produced by the gonads.
Major endocrine organs include - answer pituitary gland, thyroid gland,
parathyroid glands, thymus gland, adrenal glands, islets of Langerhans
of the pancreas, ovaries, testis.
Anterior lobe of the pituitary gland - answer location: In the brain
inferior to the hypothalamus. Hormones: Prolactin, gonadotropic
hormones, thyroid stimulating hormone, ACTH, growth hormone.
Posterior lobe of the pituitary gland - answer location: In the brain
inferior to the hypothalamus. Hormones: Antidiuretic hormone (ADH),
oxytocin.
Thyroid gland - answer location: Right and left sides of the trachea, just
below the larynx. Hormones: Tetraiodothyronine (T4), Triiodothyronine
(T3), calcitonin.
, Parathyroid glands - answer location: Four glands embedded in the
thyroid gland, located on the right and left sides of the trachea.
Hormones: Parathyroid hormone (PTH).
Adrenal glands - answer location: Found on the top of each kidney.
Hormones: Epinephrine, norepinephrine, aldosterone, hydrocortisone,
cortisone, androgens.
Pancreas - answer location: Found beneath the great curve of the
stomach. Hormones: Insulin, glucagon.
Testes, location: Male gonads. Hormones: Testosterone.
Ovaries - answer location: Female gonads. Hormones: Estrogen,
progesterone.
Thymus Gland - answer location: In the mediastinum behind the
sternum between the two lungs. Hormones: Thymosin.
Pineal gland - answer location: Found between the two cerebral
hemispheres, attached to upper part of the thalamus. Hormones:
Melatonin, serotonin.
Which organ is called the Master Organ of the Endocrine System? -
answer The pituitary gland.
