Extra Credit Lec Exam 1 PART I - The Cell Cycle & Histology (Tissues) - jayden vallinas | Biblioteka

1

Match the phases of Interphase with the major events that occur.

Stavka koja se može prevući		Odgovarajuća stavka
S		Lots of cell growth occurs
G1		Final preparations are made for mitosis
G2		DNA replication occurs; sister chromatids form

1

Match the phases of Mitosis with the statement that best describes what occurs during that phase.

Stavka koja se može prevući		Odgovarajuća stavka
Anaphase		Chromosomes align at the cell’s equator
Telophase		Sister chromatids separate and move to opposite poles
Prophase		Nuclear envelope reforms, chromosomes decondense
Metaphase		Chromatin condenses, nuclear envelope breaks down

1

Put the phases of mitosis in the correct order.

Metaphase
Prophase
Telophase
Anaphase

1

The division of the cytoplasm is known as cytokinesis.

True

False

1

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

True

False

1

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!)

Epithelial tissues regenerate well.

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.

1

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?

transitional

simple cuboidal

stratified squamous

1

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

stratified squamous

simple squamous

simple cuboidal

pseudostratified ciliated columnar

1

Match the mode of exocrine secretion to its correct description.

Stavka koja se može prevući		Odgovarajuća stavka
Merocrine secretion		Secretion where part of the cell pinches off
Holocrine secretion		Secretion via exocytosis
Apocrine secretion		Secretion where the entire cell ruptures and dies

1

Which type of connective tissue fiber is the strongest?

elastic fiber

collagen fiber

reticular fiber

1

Which connective tissue proper cell contain granules filled with histamine and heparin and plays a role in the inflammation response?

1

Which type of cartilage is best at withstanding pressure?

fibrocartilage (fibrous cartilage)

hyaline cartilage

elastic cartilage

1

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.

1

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

True

False

1

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

a diferent type of tissue

a new type of cell

a chemical bond
