Document Summary
Aims: explain the controls of cortisol release, blood sugar levels and gonadal function, compare and contrast a steroid hormone with a protein hormone, endocrine. Secretes directly into the blood or innerstital fluid. Endocrine cells interact with receptors on the target tissue cells. Target tissue has a specific receptor for that hormone. Cholesterol is hydrophobic (no charge difference between those carbon bonds). Steroids can go straight through the cell membrane: functional organization of endocrine system. Adrenals release steroids including cortisol (breaks down fat and protein supply and provides energy during times of stress) Stress level will first picked up vy cerebral hemispheres. Then transferred to the pituitary adrenals release the steroid hormones: hormone. A set of endocrine cells secreting hormones. Amino acids joined together protein: mechanism of action. All hormones are ligands for the receptors. When your pituitary releases acth adrenal glands will have the receptor to interact with the ligands: classes of hormone receptors.
