  1. Hormones and the Endocrine System Introduction to Regulatory Systems Chemical Signals and their Modes of Action Vertebrate Endocrine System

  2. Introduction to Regulatory Systems • Nervous system involved with high speed responses • Endocrine system is slower and involves the production, release, and movement of chemical messages • specialized nerve cells found within the endocrine system are called neurosecretory cells • some chemicals function in both systems-ex. norepinephrine

  3. Two Classes of Vertebrate Hormones • Most signal molecules are unable to diffuse through the plasma membrane (peptides, proteins, glycoproteins), require a membrane receptor and signal transduction pathway • some molecules can diffuse through the membrane (steroids, thyroid hormones, NO), receptors are within the target cells

  4. Vertebrate Endocrine System • Hypothalamus and pituitary integrate much of the endocrine system • includes: hypothalamus, anterior and posterior pituitary, pineal, thyroid, parathyroid, pancreas, adrenal, testis, and ovary

  5. Diabetes • Two types: • Type I- Insulin dependent • Type II-Non-insulin dependent
