Epithelium And Connective Tissue

Question 1

4 types of tissue

Answer 1

Epithelial, connective, muscle, nervous

Question 2

Functions of epithelium

Answer 2

Protection(skin), secretion(glands), absorption(GI tract), filtration(kidneys)

Question 3

Epithelium classification

Answer 3

Shape (squamous, cuboidal, columnar)
Layer (simple, stratified) (named by top layer)
Pseudostratified
Transitional

Question 4

Pseudostratified

Answer 4

“False layers”=simple
All cells attached to basement membrane but cell nuclei appear at different levels

Question 5

Transitional

Answer 5

Stratified, stretchy cells, the surface layer appears domed (bladder expansion)

Question 6

Epithelium tissue

Answer 6

Tightly connected cells that form membranes/sheets surface faces of outside of body or inside of tube. It is avascular and the cells divide rapidly. Anchored to basement membrane

Question 7

Connective tissue function

Answer 7

Binding(tendons, ligaments)
Support(bones, cartilage)
Protection(bones, cartilage, adipose)
Insulation(adipose)
Transportation(blood)

Question 8

Connective tissue characteristics

Answer 8

Mostly well vascularized, loosely connected cells (suspended in matrix)

Question 9

Matrix

Answer 9

Fibers (proteins, collagen, elastic, reticular) + ground substance (fluid)

Question 10

Types of mature connective tissue

Answer 10

Bone, cartilage (hyaline, fibrocartilage, elastic cartilage), dense (dense regular, dense adipose, elastic), loose (areolar, adipose, reticular), liquid (blood, lymph)

Question 11

Connective tissue cell types

Answer 11

Fibroblasts (cells that make fibers)
Macrophage (resident white blood cells important for immune defense)
Mast cells (make heparin (anti-clotting) and histamine)
