1. CT, Nerve, and Tissue Repair/Aging etc.
This is not all inclusive!! Refer to your notes and tissue coloring packet!!

2. Format 8 MC 3 Lost Sheet 9 Matching
Tissue Identifications and Labeling
Choice of Short Answer (2 to choose from)
Point value= TBD

3. Connective Tissue Originate from embryonic tissue called mesenchyme
Most diverse and abundant type of tissue
Function: to protect, support and bind together other tissues
Bones, ligaments, tendons
Areolar cushions; adipose insulates and is food source
Blood cells replenished; body tissues repaired
Cells separated from one another by large amount of nonliving extracellular matrix

4. Extracellular Matrix explained
Nonliving material between cells
Produced by the cells and then extruded
Responsible for the strength
Two components
Ground substance
Of fluid, adhesion proteins, proteoglycans
Liquid, semisolid, gel-like or very hard
Fibers: collagen, elastic or reticular

5. Basic functions of connective tissue reviewed
Support and binding of other tissues
Holding body fluids
Defending the body against infection
macrophages, plasma cells, mast cells, WBCs
Storing nutrients as fat

6. Classes of Connective Tissue*

10. Classes of Connective Tissue*

18. Spongy bone Blood surrounds bone Squishy end of bone
Under the cartilage cap (or articular cartilage)

19. Four basic types of tissue
Epithelium
Connective tissue
Muscle tissue
Nervous tissue
Neurons
Supporting cells

21. Tissue response to injury
Immune: takes longer and is highly specific
Inflammation
Nonspecific, local, rapid
Inflammatory chemicals
Signs: heat, swelling, redness, pain
Repair – two ways
Regeneration
Fibrosis and scarring
Severe injuries
Cardiac and nervous tissue

22. 3 types of cells Labile Stable Permanent
Cells that divide all throughout your life
Ex: skin/ mucous membranes
Repaired through regeneration
Stable
Cells that retain the ability to divide AFTER injury BUT do not divide regularly once growth has stopped
Ex: Bone & Glands
Completed through (mainly) regeneration, but some replacement
Permanent
Little or no ability to divide. If they are destroyed they are replaced by Connective Tissue (scar tissue!!)
Ex: Nerve cells, Skeletal/Muscle Cells

23. Shrinkage/Death Atrophy
Shrinkage of tissue through decrease in cell size or number
Normal Aging (senile)
Lack of Use (disuse)
Necrosis
Premature pathological death of tissue due to trauma/ infection/toxin
Gangrene – necrosis due to insufficient blood supply
Infarction – sudden tissue death (ie. Heart Muscle)
Apoptosis
Programmed cell death (normal!)
Cells are quickly phagocytized by WBC
No inflammation
In embryo – webbing between fingers/toes
Shrinkage of uterus after pregnancy
