SCIENCE WEEK 2 - The Endocrine and Nervous System Flashcards
Two ways body processes are regulated
- through nervous system
- chemically - by hormonal secretions of the endocrine system
is made up of a group of organs called endocrine glands.
Endocrine System
comes from the Greek word “Endo” meaning with, and “Crinis” meaning secrete
Endocrine
The endocrine gland is also called as:
ductless gland
are the secretions of the endocrine glands.
Hormones
are special protein substances
Hormones
bring about changes in cells or tissues
Hormones
effects may be an increase or decrease activity of target cells
Hormones
effects may just also be to maintain cells
Hormones
located at the middle of the brain
Pineal Gland
Hormone secreted by Pineal Gland
Melatonin
Helps regulate daily sleep-wake cycle or seasonal rhythms associated with existing light condition
Melatonin
at the lower central area of the brain
Hypothalamus
Hormones produced by Hypothalamus
Oxytocin
Antidiuretic Hormone
regulates body temperature and body pressure, and water loss
Antidiuretic Hormone (ADH)
Regulates activities of the body, metabolism, and reproduction.
Oxytocin
located beneath the Hypothalamus
Pituitary Gland
regulates growth of skeletal system
Pituitary Gland
it stimulates adrenal and thyroid gland to release specific hormones
Pituitary Gland
Hormones produced by anterior lobe
Growth, Thyroid-Stimulating Hormone, Adrenocorticotropic Hormone, follicle stimulating hormone (FSH), Luteinizing hormone (LH), Prolactin
stimulate growth of bones
Growth Hormones
regulates the activity of the thyroid gland
Thyroid-Stimulating Hormone
stimulates adrenal cortex to produce steroid hormone
Adrenocorticotropic Hormone
stimulate gamete formation
Follicle Stimulating Hormone
stimulates production of estrogen and progesterone
Luteinizing Hormone
stimulate milk production
Prolactin
hormones produced by Middle Lobe
Melanocytes-Stimulating Hormones
enhances production of melanin pigment
Melanocytes-Stimulating Hormones
hormones created by Posterior Lobe
Oxytocin, Vasopressin
regulates contraction during childbirth
Oxytocin
prevents water loss in the body
Vasopressin
located in front of pituitary gland
Thyroid Gland
Hormones produced by Thyroid Gland
Thyroxine, Triiodothyronine, Calcitonin
regulates rate of metabolism
Thyroxine
regulate mental and physical
growth
Triiodothyronine
regulates calcium in the blood
Calcitonin
4 tiny glands connected to the back of the thyroid gland.
Parathyroid Gland
hormone produced by Parathyroid
Parathormone
Regulates the minerals in the body - calcium and phosphorus in bloodstream
Parathormone
placed on top of the kidneys
Adrenal Gland
Hormones produced by adrenal gland
Glucocorticoids, Mineral corticoids, Androgens, Adrenaline
regulates metabolism
Glucocorticoids
regulates immune system
Mineral corticoids
regulates blood pressure
Androgens
regulates response to stress
Adrenaline
decreases the amount of sugar in the bloodstream
Insulin
it prevents your blood sugar from dropping too low; increases the body sugar level
Glucagon
Controls growth and development of male sex organ and other secondary and sex characteristics
Testosterone
Controls the development of female secondary sex characteristics
Estrogen
Stimulates the growth of uterus lining
Progesterone
function of endocrine system
regulates body processes chemically through its hormonal secretions
