Exam 1 A&P

• Nervous system and endocrine system work together to maintain homeostasis
• Endocrine system uses chemical signaling to comunicate
• Endocrine glands are: Pituitary, Thyroid, Parathyroid, Adrenal and pineal glands
• Endocrine organs The hypothalamus, thymus, heart, kidneys,stomach, small intestine, liver, skin, femaleovaries, and male testes
• Exocrine glands (think exit)• The sebaceous and sweat glands of theskin
• What are the 4 types of hormones?

  Amine, Peptide, Protein and Steroid
• Amine Hormones are made from tryptophan or tyrosine amino acids
• Amine hormones include?

  melatonin, epinephrine, norepinephrine, and dopamine
• Peptide hormones are short chains of amino acids EX ADh and atrial natriuretic peptide
• Protein hormones are longer polypeptides Ex Growth Hormone and FSH
• Steroid Hormones from lipid cholesterol, EX testosterone and estrogen
• The message a hormone sends isreceived by a hormone receptor
• Intracellular hormone receptors arelocated inside the cell
• The hypothalamus pituitary complex can bethought of as the “command center” of theendocrine system
• The Pituitary is bean shaped and contains 2 lobes: Posterior pituitary and Anterior Pituitary
• The Infundibulum stems off to form the Anterior and Posterior Pituitary lobes
• The Posterior Pituitary gland hormones include oxytocin and ADH
• Oxytocin stimulates uterine contractions and cervix dilation
• ADH Regulates urin in the kidneys. Alcohol inhibits the release of ADH by your pituitary gland which makes you have to pee.
• 1. The anterior pituitary produces seven hormones, which are: Growth hormone (GH)Thyroid stimulating hormone (TSH)Adrenocorticotropic hormone (ACTH) Follicle-stimulating hormone (FSH) Luteinizing hormone (LH) Beta endorphin Prolactin
