Endocrine System- Sarah Heard pd6
Major functions
Endocrine glands secrete hormones into the blood then carried through the body
these hormones help regulate growth, metabolism, and sexual development
Major endocrine glands
Adrenal
Function (two layers)
Adrenal cortex
outer layer
Glucocorticoids or cortisol- responds to stress or injury and releases anti- inflammatory
Adrenal Medulla
inner layer
adrenaline- simulates "fight or flight" response
Hormone
ACTH
Location
on top of kidneys
parathyroid
Function
produces parathyroid hormone which increases blood calcium levels
Location
On posterior side is the parathyroid
Thymus
Function
produces thymosin hormone- stimulates the development of the T-cells involved in the immune response
Location
piece of flesh that lays on top of heart
Pancreas
Function
controls blood sugar levels
Glucagon
increase blood glucose
Insulin
decrease blood glucose
Location
upper abdominal on left side behind stomach
Thyroid
Function
produces thyroid hormone &controls your metabolism
Location
In front of Adams apple
hormone
calcitonin
decreases calcium in blood when there is too much
Hormones
def: Chemical messengers, produced by endocrine cells, that travel in blood and influence certain cells elsewhere in the body.
neurotransmitters that act as hormones
cortisol, aldosterone, estrogen, testosterone, epinephrine, norepinephrine, and histamine
melatonin
controls sleep cycles, alertness, and temperature
Antidiuretic Hormone (ADH)
regulates fluid balance by increasing body fluid volume and decreasing urine output
Oxytocin
stimulates contraction of the uterus during labor and milk or ejection from alveoli
Follicle stimulating hormone (FSH)
stimulates egg maturation in the ovary and release sex hormones
Luteinizing hormone (LH)
Both involved with development of ovaries and testes
Adrenocorticotropic hormone (ACTH)
stimulates the adrenal gland to release cortisol
Human growth hormone (HGH)
stimulates growth during infancy and puberty
Prolactin
initiates and maintains milk secretion
Thyroid stimulating hormones (TSH)
control basal metabolic rate by releasing thyroxine
melanocyte stimulating Hormone (MSH)
stimulates production of melanin in the skin
Diseases
Thyroid Cancer
Symptoms of pain are very uncommon except in inflammatory conditions of the thyroid
most common symptom is a lump in the neck
Addison's Disease
rare disorder that affects men and women of all ages
develops when your adrenal glands do not produce enough of the hormone cortisol
Osteoporosis
If you have osteoporosis, your bones are weak and prone to fracture
osteoporotic bone has holes bigger than a healthy bone
Graves' Disease
type of autoimmune problem that causes the thyroid gland to produce too much thyroid hormone
Graves’ is also more likely to affect women than men.
Type 1 diabetes
autoimmune condition in which the pancreas can no longer produce insulin to control your blood sugar naturally
