Resource summary
INTRO TO ENDOCRINE SYSTEM
Endocrine glands and hormones they release influence every cell in the body
Regulates mood, growth, tissue function, metabolism, reproductive system
Made up of DUCTLESS GLANDS and release HORMONES
HORMONES - chemicals that act as messengers
Produced in endocrine glands
Sent through the bloodstream to an organ or gland
PITUITARY GLAND
Situated in STELLA TURCIA of SPHENOID
MASTER GLAND
ANT,MIDDLE,POST LOBES
Regulates act of endo glands and work with hypothalamus
ANTERIOR LOBE regulates-thyroid, adrenals, reproductive
Produces GH - stimulates growth of bone and tissues
Produces PROLACTIN - Milk production
Produces THYROTROPIN - stimulates thyroid to release hormones
Produces CORTICOTROPIN - stimulates adrenal gland
Secretes ENDORPHINS - reduces pain
Pituitary controls OVULATUION
POSTERIOR LOBE
Releases ANTIDIURETIC HORMONE
controls water balance
OXYTOCIN - contraction of uterus
THYROID GLAND
Situated in the neck, close to Larynx and Trachea
Produce THYROXINE and TRIIODOTHYRONINE
in the presence of CALCITONIN and IODINE
butterfly shape, on each side of T CARTILAGE
These hormones control the rate which cells burn fuel from food
Play key role in bone growth, brain and nervous system
The release of Thyroid hormones is controlled by THYROTROPIN
PARATYHROID GLANDS
Attached to Thyroid - 4 tiny glands, lying on posterior
Release PARATHYROID HORMONE
Regulates level of CALCIUM in blood with hormone CALCITONIN
ADRENAL (SUPRARENAL) GLANDS
Situated above Kidneys
Made up of an outer part - ADRENAL CORTEX
An inner part - ADRENAL MEDULLA
ADRENAL CORTEX
Produces hormone - CORTICOSTEROIDS
Regulate SALT and WATER BALANCE
IMMUNE SYSTEM, STRESS, SEXUAL DEVELOPMENT
ADRENAL MEDULLA
Produces CATECHOLAMINES
such as EPINEPHRINE (ADRENALINE)
Increases BP and HEART RATE in times of stress
PANCREAS - Produces INSULIN and GLUCAGON
Maintain a healthy level of GLUCOSE/SUGAR in the blood
ISLETS OF LANGERHANS
Found in the PANCREAS
BETA CELLS-INSULIN
ALPHA CELLS-GLUCAGON
DELTA CELLS-SOMATOSTATIN
THYMUS
mediastinum behind sternum
Atrophy after puberty
secretes Thymosin - maturation of T-LYMPHOCYTES
PINEAL GLAND
Third ventricle in brain
Atrophy after puberty
Secretes MELATONIN
regulates wake/sleep cycle
