Unit 7 Day 9 Anatomy The only normal people are the ones you don’t know very well. Foe Ancis
Today’s Agenda • Review hormone traits • Notes on types of hormones • Endocrine system coloring
What makes a chemical a hormone? • 1. Endocrine gland • 2. Blood stream • 3. Target cells
Classification of Hormones • Steroid Hormones – fat soluble, made from cholesterol. • Ex. Sex hormones • Protein Hormones – made from amino acids, usually from tyrosine, smaller than steroid hormones. • Peptide Hormones- chains of amino acids • Very diverse group
Two types of hormone action • Steroid hormones • Peptide hormones
Label your diagram • 1. Steroid Hormone • 2. Hormone receptor • 3. Hormone and receptor attach to a specific region of the chromosome. • 4. DNA transcribed to mRNA • 5. mRNA translated into a protein
Example • 1. Steroid Hormone-Testosterone • 2. Hormone receptor-in lip cell • 3. Hormone and receptor attach to a specific region of the chromosome. Containing Hair Instructions • 4. DNA transcribed to mRNA • 5. mRNA translated into a protein- Hair
TM 84 Boxes • Protein Hormone (top box) • Glycogen (lower left) • Glucose (lower right)
Protein Hormones • Much faster action than steroid hormones • Do not enter the target cell • Ex. Adrenalin
Hormones and their glands
Your opinion? • Growth hormone is now available as a prescribed treatment. Should doctors be allowed to give it to anyone desiring to be taller?
