Tissues Flashcards
Name the four primary tissues
Epithelial, Connective, Muscle, and Nervous
What is the main purpose of epithelial tissues?
Covers and lines other tissues
Epithelial tissue is found where?
Bladder, mouth, blood vessels, thorax, and all body cavities
Three cellular attachments
Tight junction, desmosome, and gap junction
8 different types of epithelial tissue
Simple squamous, simple cuboidal, simple columnar, stratified squamous, stratified cuboidal, stratified columnar, and pseudostratified columnar.
What is the main purpose of connective tissues?
Serves as a “protective sheath” around organs
Composed of 3 different elements
Ground substance, extracellular fibers, and cells
Loose connective tissues are…
Areolar, adipose, and reticular
Dense connective tissues are…
Dense regular, dense irregular, and elastic
Specialized connective tissues are…
Cartilage(hyaline, elastic, and fibrocartilage), bone, and blood
Areolar tissue is found…
Everywhere
Adipose tissue functions as a
Shock absorber
Reticular tissue provides
An internal skeleton for the spleen, lymph nodes, and bone marrow
Example of dense regular
Tendons and ligaments
Example of dense irregular
Joint capsules
Four types of epithelial membranes
Mucous, Serous, Cutaneous, and synovial
Mucous membranes are found where?
Digestive tract, respiratory tract, urinary tract, and the reproductive tract
Normal color of mucous membranes?
Pink
Serous membranes…
Line the walls and cover the organs in closed body cavities
Cutaneous membranes are found in the?
Skin
Synovial membranes line?
Joint cavities
Three types of muscle tissues
Skeletal, smooth, and cardiac
Skeletal muscle is voluntary or involuntary?
Voluntary
Smooth muscle is voluntary or involuntary?
Involuntary
Cardiac muscle is voluntary or involuntary?
Involuntary
Nervous tissue is found where?
Brain, spinal cord, and peripheral nerves
Steps of inflammation…
- Initial vasoconstriction
- Fluid flows to the area, pain and swelling begin
- Clot formation begins
- WBC’s move out of vessels and into the area
- Increase blood flow
First intention healing
Sutured wounds and no formation of granulation tissue
Second intention healing
Granulation tissue form to close the wound
Third intention healing
Larger wounds, healing comes more slowly
