Transcript of "Endocrine System, Nervous System And Homeostatic Control[1]"

  1. 1. Endocrine System, Nervous System and Homeostatic Control
  2. 2. Endocrine system <ul><li>Information signaling system </li></ul><ul><li>Glands produce hormones </li></ul><ul><li>Circulate through blood vessels </li></ul><ul><li>Regulate: </li></ul><ul><ul><li>mood , growth and development , tissue function , and metabolism </li></ul></ul>
  3. 3. Hypothalamus <ul><li>The hypothalamus controls body temperature , hunger , thirst , fatigue, anger, and circadian cycles . </li></ul><ul><li>Secretes hormones that tell other glands to create their hormones </li></ul><ul><ul><li>GHRH </li></ul></ul>
  4. 4. Pineal Body <ul><li>Secretes Melatonin </li></ul><ul><li>Melatonin may help regulate sleep patterns </li></ul>
  5. 5. Pituitary Gland <ul><li>Growth </li></ul><ul><li>Blood Pressure </li></ul><ul><li>Sex Organ Functions </li></ul><ul><li>Conversion of food into energy </li></ul><ul><li>Water regulation </li></ul>
  6. 6. Thyroid <ul><li>Controls how quickly the body burns energy , makes proteins , and how sensitive the body should be to other hormones . </li></ul>
  7. 7. Parathyroid <ul><li>The sole function of the parathyroid glands is to maintain the body's calcium level within a very narrow range. </li></ul>
  8. 8. Pancreas <ul><li>Regulates blood sugar by producing Insulin </li></ul>
  9. 9. Adrenal gland <ul><li>Produces Adrenaline </li></ul><ul><li>Fight or Flight Response </li></ul><ul><ul><li>Dilate pupils </li></ul></ul><ul><ul><li>Increase heart rate </li></ul></ul><ul><ul><li>Suppress non emergency process </li></ul></ul><ul><ul><li>Boost oxygen and glucose supply </li></ul></ul>
  10. 10. Testes and Ovaries <ul><li>Both produce hormones to support body function </li></ul><ul><li>Testes </li></ul><ul><ul><li>Testosterone </li></ul></ul><ul><li>Ovaries </li></ul><ul><ul><li>Progesterone </li></ul></ul><ul><ul><li>Estrogens </li></ul></ul>
  11. 11. Nervous system <ul><li>Made up of two major parts </li></ul><ul><ul><li>Central Nervous System (CNS) </li></ul></ul><ul><ul><li>Peripheral Nervous System (PNS) </li></ul></ul>
  12. 12. Neurons
  13. 13. Central Nervous System <ul><li>Brain and Spinal Cord </li></ul><ul><ul><li>Nerves </li></ul></ul><ul><ul><li>Ganglion </li></ul></ul>
  14. 14. Brain <ul><li>Consists of lobes, Each lobe having different functions. </li></ul>
  15. 15. Function <ul><li>Process information </li></ul><ul><li>Dictate reactions and behaviors </li></ul>
  16. 16. Peripheral Nervous system <ul><li>Nerves from spinal cord to rest of body </li></ul><ul><li>Create locomotion </li></ul><ul><li>Etc… </li></ul>
  17. 17. Feedback Loops <ul><li>Your nervous system is involved in almost all homeostatic control loops. </li></ul><ul><li>Reflex arc </li></ul><ul><li>Sensory Vs Motor </li></ul><ul><li>Affector Vs Effector </li></ul>
  18. 19. Neuron Function <ul><li>Dendrites </li></ul><ul><li>Myelin </li></ul><ul><li>Schwann Cells </li></ul><ul><li>Axon </li></ul><ul><li>Node of Ranvier </li></ul>
  19. 20. Threshold <ul><li>Before a neuron can send out a signal the stimuli has to pass the threshold </li></ul>
  20. 21. Action Potential <ul><li>An action potential is a nerve impulse </li></ul><ul><li>An electrical shock sent down the axon </li></ul>
  21. 22. Action Potential
  22. 23. Synapse <ul><li>A synapse occurs where ever the action potential meets the end of the axon </li></ul><ul><li>It needs to propagate across that gap </li></ul><ul><li>It does this through chemical messengers </li></ul>
  23. 24. Neurotransmitter= Acetylcholine Enzyme that destroys it = Acetylcholinesterase
  24. 25. Synapse <ul><li>When Acetylcholine jumps across the gap, it tells the next neuron to fire it’s action potential and the process continues </li></ul>
  25. 26. Homeostasis Summary <ul><li>Homeostasis is the maintenance of a stable internal state within an organism. </li></ul><ul><li>Organisms must respond and maintain homeostasis in relation to many factors. </li></ul><ul><li>Organisms detect changes in their environment and respond to these changes in a variety of ways.    </li></ul><ul><li>These changes may occur at the cellular or organism level. </li></ul>
