  1. Unit 2 Day 7 2004 Anatomy

  2. “It is better to be hated for what you are than loved for what you are not.” • Andre’ Gide

  3. Today’s Agenda • Warm-up (from Friday’s work) • Objective 6 notes • Tissue Notes (obj. 8) • Begin Tissue Lab

  4. Complete the bottom part of the warm-up

  5. Objective 6 • DNA replication: Occurs in the S stage of the cell cycle. Replication results in an exact copy of each strand of DNA found within the cell.

  6. Obj. 7 Types of Tissues • Examples on overhead

  7. Objective 8 Epithelial Cell Traits • Cellularity --made of cells • Specialized contacts: • tight junctions • gap junctions • desmosomes • Avascular means no blood vessels

  8. Objective 8 • 5. Basement Membrane • 6. Regeneration Basal lamina

  9. Obj 9 &10 Connective tissue • Characteristics • Common origin-they come from mesenchyme • Varying degrees of vascularity (blood vessels) • Contain a lot of extracellular matrix.

  10. Types • Embryonic----in embryo, precursor to all • Loose--wraps and cushions organs • Adipose--stores food reserve • Reticular--soft support, network of fibers • Dense--attaches muscle to bones.

  11. Irregular--provides strength, withstands tension • Elastic--Provides durability with stretch • Hyaline--Support, cushions, reinforces, tough • Bone--forms bones • Blood--liquid matrix

  12. Objective 11 • Smooth muscle-found in viscera • Cardiac muscle--found in heart • Skeletal muscle--movement

  13. Objective 12: Nervous Tissue • Central nervous system’s tissues process information and are located in the brain and spine.

  14. Objective 12: Nervous Tissue • Peripheral nervous system tissues relay information to and from the central nervous system. These tissues include the NERVES and GANGLION

  15. Practice Identifying Tissues
