INTRO TO ENDOCRINE SYSTEM
  1. Endocrine glands and hormones they release influence every cell in the body
    1. Regulates mood, growth, tissue function, metabolism, reproductive system
      1. Made up of DUCTLESS GLANDS and release HORMONES
    2. HORMONES - chemicals that act as messengers
      1. Produced in endocrine glands
        1. Sent through the bloodstream to an organ or gland
      2. PITUITARY GLAND
        1. Situated in STELLA TURCIA of SPHENOID
          1. MASTER GLAND
            1. ANT,MIDDLE,POST LOBES
              1. Regulates act of endo glands and work with hypothalamus
                1. ANTERIOR LOBE regulates-thyroid, adrenals, reproductive
            2. Produces GH - stimulates growth of bone and tissues
              1. Produces PROLACTIN - Milk production
                1. Produces THYROTROPIN - stimulates thyroid to release hormones
                  1. Produces CORTICOTROPIN - stimulates adrenal gland
              2. Secretes ENDORPHINS - reduces pain
                1. Pituitary controls OVULATUION
                2. POSTERIOR LOBE
                  1. Releases ANTIDIURETIC HORMONE
                    1. controls water balance
                      1. OXYTOCIN - contraction of uterus
                3. THYROID GLAND
                  1. Situated in the neck, close to Larynx and Trachea

                      1. These hormones control the rate which cells burn fuel from food
                        1. Play key role in bone growth, brain and nervous system
                          1. The release of Thyroid hormones is controlled by THYROTROPIN
                      2. PARATYHROID GLANDS
                        1. Attached to Thyroid - 4 tiny glands, lying on posterior
                          1. Release PARATHYROID HORMONE
                            1. Regulates level of CALCIUM in blood with hormone CALCITONIN
                      3. ADRENAL (SUPRARENAL) GLANDS
                        1. Situated above Kidneys
