1
Q

The study of tissues

A

Histology

2
Q

The four basic tissue types

A
  1. Epithelial
  2. Connective
  3. Muscle
  4. Nervous
3
Q

Widespread throughout the body, covering the body’s outer and inner surfaces, lining the inner surfaces of tubular organs

A

Epithelial

4
Q

Main functions are protection and transport. Specialized functions include sensory reception and the maintenance of the body’s gametes

A

Epithelial

5
Q

What is the shape of the outermost cells of epithelial tissues

A

Squamous, cuboidal, or columnar (all are polygonal)

6
Q

How many layers of cells are there in epithelial tissues?

A

Epithelial tissues are simple if there’s one layer of cells; stratified if there are two or more

7
Q

Contain large amount of material external to the cells, called extra cellular matrix

A

Connective tissue

8
Q

Extracellular matrix

A

Consists of fibers embedded in ground substance (collagen and elastic)

9
Q

Fibers are tough, flexible, and inelastic

A

Collagen

10
Q

Fibers stretch when pulled, returning to their original length when the pull is removed

A

Elastic fibers

11
Q

Contain blood vessels

A

Connective tissues

12
Q

Forms much of the packing material of the body and fills in the spaces between other tissues

A

Loose connective tissues

13
Q

The cell that produces the matrix of loose and other soft connective tissues

A

Fibroblast

14
Q

Composes the second layer of the skin

A

Dense irregular fibrous connective tissue

15
Q

The space within any hollow organ

A

Lumen

16
Q

Cartilage cells

A

Chondrocytes

17
Q

Hardness due to minerals deposited in matrix, flexibility comes from having highest collagen content

A

Bone tissue

18
Q

Has to diffuse across the matrix between chondrocytes and blood vessels surrounding connective tissue

A

Cartilage
