Question 3
3.

Put the phases of mitosis in the correct order.

  1. Prophase
  2. Metaphase
  3. Anaphase
  4. Telophase
Question 4
4.

The division of the cytoplasm is known as cytokinesis.

Question 5
5.

Mitosis and cytoplasmic division result in the formation of two genetically identical cells.

Question 6
6.

CHOOSE ALL THAT APPLY!!!  Which of the following are characteristics of epithelial tissue?  (There are more than 1 answer to this question!  Select them all!)

Question 7
7.

If an epithelial tissue has one layer of cells that are square-ish shaped - which of the following would be an appropriate name for it?

Question 8
8.

Because it has multiple layers, this epithelium is the best at protecting against rubbing and abrasion.

Question 9
9.

Match the mode of exocrine secretion to its correct description.

Secretion where part of the cell pinches off
Apocrine secretion
arrow_right_alt
Secretion via exocytosis
Merocrine secretion
arrow_right_alt
Secretion where the entire cell ruptures and dies
Question 10
10.

Which type of connective tissue fiber is the strongest?

Question 11
11.

Question 12
12.

Which type of cartilage is best at withstanding pressure?

Question 13
13.

Question 14
14.

Cardiac muscle tissue, nervous tissue and cartilage connective tissues are all BAD at regeneration.

Question 15
15.

When epithelial tissue is combine with connective tissue - you form _____________________.

Nuclear envelope reforms, chromosomes decondense
Anaphase
Chromatin condenses, nuclear envelope breaks down
Epithelial tissues are supplied with many blood vessels.
Epithelial tissues exhibit polarity which means they have a top apical surface, and a bottom basement membrane (basal surface).
Epithelial cells exhibit cellularity which means their cells are packed closely together.
Epithelial tissue is often supported by connective tissue.
Which connective tissue proper cell contain granules filled with histamine and heparin and plays a role in the inflammation response?
macrophage
adipocyte
mesenchymal cell
mast cell
fibroblast
fibrocyte
lymphocyte
melanocyte
CHOOSE ALL THAT APPLY!!!  The following statements are about nervous tissue and muscle tissue.  Select all the TRUE statements.  (hint:  I made 4 true statements so pick all 4 of them!)
The two types of cells that make up nervous tissue are the neurons and the neuroglia (supporting) cells.
Neuroglia (supporting) cells are responsible for generating and conducting impulses that allow for communication between structures in the body.
Muscle tissue is unique because it is the only tissue capable of contraction (shortening) and thus produces movement in the body.
Skeletal muscle and cardiac muscle are both under voluntary control.
Skeletal muscle and cardiac muscle are both striated.
Smooth muscle is both involuntary and unstriated.
