Presentation Transcript

  1. Animal Tissues

  2. Epithelial tissue • Simple (single layer) cuboidal (cube shape) • Simple columnar (single layer of column shape)

  3. Nervous Tissue • Neuron (nerve cell): Cell body, dendrite, axon. Glial cells support the neuron

  4. Neurotransmitter crosses synapse

  5. Schwann cells make up the myelin sheath. Impulse jumps from node to node

  6. 3 types of muscle tissue: skeletal, smooth, cardiac

  7. Striations Intercalated discs

  8. Loose connective tissue (under skin and epithelial tissue)

  9. Bone • Haversian canal with blood vessel and nerve • Lacuna openings with osteocytes in them • Calcium carbonate matrix

  10. Blood:Erythrocytes, red blood cells • Hemoglobin carries oxygen • No nucleus • Made in bone marrow

  11. Leukocytes: White blood cells

  12. Thrombocytes: platelets • Platelets adhering to damaged vessel

  13. Blood composition • RBC (hematocrit) 40% • WBC 1% • Platelets 1% • Plasma 58%

  14. Tendon: bone to muscleMore flexible and thicker

  15. Ligament: bone to boneNot as flexible or thick

  16. REVIEW QUESTIONS • What are the scientific names for the three types of cells in blood? • What is released by basophils to stimulate inflammatory response? • What type of protein makes up the ACL? • What part of the blood is used for DNA fingerprinting?

  17. What muscle tissue branches? • What muscle tissue is involuntary and lines digestive tract? • What type of epithelium tissue is found inside the cheek? • What is adipose?

  18. REVIEW • What is in the lacuna? • Which is thicker tendons or ligaments? • What tissue has matrix? • What makes calcium carbonate in bones?
