Unit 2 Day 7 2004

In this lesson, students will explore the various types of tissues in the human body, focusing on epithelial, connective, muscle, and nervous tissues. Through warm-up activities, in-depth notes, and a tissue lab, participants will gain insights into tissue characteristics, functions, and origins. Key concepts include the vascularity of tissues, the role of extracellular matrix, and the unique properties of each tissue type. By the end of the session, students will be able to identify and describe the main types of tissues and their functions in the body.

  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
