Question
1

List the four main tissue types found in the human body. (4 points)
Connective tissue
Epithelial tissue
Muscle tissue
Nervous tissue

2

Are epithelial tissues vascular or avascular? Please explain your answer. (1
point)
Avascular. Avascular simply means it doesn’t have a blood flow. This
is an advantage, because we can constantly shed and reproduce new
epithelial tissue without it hurting our bodies. Our skin, for instance, is
made up of epithelial tissue.

3

What are the four functions of epithelial tissues? (8 points)
Covers and lines the bodys surface (protection)
Cells are densely packed together with minimal amount of intercellular
substance
Cells are firmly attached by intercellular junctions
Cells rest on a basement membrane partly derived from underlying
connective tissue

4

What two characteristics are used to classify epithelial tissues? (4 points)
Shape
Number of cell layers

5

Stratified squamous

6

Name the following type of epithelial tissue. (5 points)

Stratified columnar

7

What are the three functions of connective tissues? (6 points)
Protection
Support
Binding of other tissue

8

Name the three elements found in connective tissues. (3 points)
Ground substance
Fibers
Cells

9

Describe the three types of fibers found in connective tissues. (3 points)
Collagen, collagen fibers are primarily made up of protein, they also contain
cross-linked fibrils that make the fibers tough and which give them the
ability to resist longitudinal stress.
Elastic, elastic fibers contain the protein. Elastin allows the fibers to stretch
and recoil. Elastic fibers are long and thin and form branched networks.
Reticular, reticular fibers are short, fine, collagenous fibers that branch
extensively to form fibrous networks that surround small blood vessels and
support soft tissues of organs.

17

Is muscle tissue vascular or avascular? (2 points)
Vascular

18

Which type of muscle tissue is considered voluntary muscle tissue? (2
points)
Skeletal muscle

19

Identify the following type of muscle tissue. (5 points)

Cardiac muscle tissue
20
