A&P Unit 4 5 6 7

Question 1

How many phases does Interphase have

Answer 1

Subdivided into three Subphases

G1, S, G2

Question 2

What does G1 do?

Answer 2

The cell begins to replicate its centrioles on preparation for cell division

Question 3

What is S Phase

Answer 3

Replication where DNA synthesis occurs.
The cell makes an identical copy of its genetic material so that each daughter cell produced during the mitotic phase will have one complete set of chromosomes and will be generically identical to the parent cell.

Question 4

What is G2

Answer 4

The cell continues to grow, synthesize the protein necessary for cell division, and completes the productions and completes the production of new centrioles. It becomes ready to enter the mitotic phase.

Question 5

How many phases does mitotic phases have

Answer 5

Mitosis and Cytokinesis

Question 6

What are the 4 phases of Mitosis

Answer 6

Prophase, Metaphase, Anaphase, and Telophase

Question 7

What phase has the duplicated chromosomes coil and become visible, the nuclear envelope breaks down, the centrioles move to opposite poles of the cell

Answer 7

Prophase

Question 8

Metaphase

Answer 8

The Chromosomes line up along the metaphase plate (Equator)

Question 9

Telophase

Answer 9

The Sister chromatids uncoil reach the opposite poles and uncoil to become chromatin reach the opposite poles and uncoil to become chromatids once again as new nuclear enevelopes form around each mass of chromatin.

Question 10

Anaphase

Answer 10

The sister chromatids of each chromosome split apart and move to opposite poles of the cell

Question 11

Basement Memebrane

Answer 11

An epithelium consists of tightly packed cells sitting on adhesive, acellular struture

Answer 16

Cuboidal

Question 17

What is column-shaped called

Answer 17

Columnar

Question 18

Answer 18

Simple Squamous epithelium

Question 19

A single of layer of cube-shaped epithelial cells and a single layer of column-shaped cells

Answer 19

Simple Cuboidal epithelium and simple columnar epithelium

Question 20

what consists of two or more cell layers in which the basal cells are cuboidal or columnar but the apical cells

Answer 20

Stratified squamous epithelium

Question 21

Stratified Squamouse Epithelia is subdivided into two types

Answer 21

Nonkeratinized and Keratinized

Question 22

Where is nonkeratinized stratified squamous epithelium found?

Answer 22

Found in the moist lining of the mouth, esophagus, and vagina, the outer most layer of cells are living

Question 23

Where is keratinized stratified squamous epithelium found?

Answer 23

Only found on the outermost cells are dead and filled with waterproofing protein keratin

Question 24

What are two or more layers of cube-shaped cells called

Answer 24

Stratified Cuboidal Epithelium

Question 25

What are two or more layers of column-shaped cells called

Answer 25

Stratified columnar epithelium

Question 26

Pseudostratified columnar epithelium

Answer 26

Trachea, consists of column-shaped cells of differing heights containing nuclei at different levels of the cells. Can be ciliated or nonciliated

Question 27

Transitional epithelium

Answer 27

is stratified epithelium found onlu in the urinary system. Dome shaped cells on its apical surface change shape according to the degree of stretch required of the structure in which they are found

Question 28

what is the more widespead tissue type

Answer 28

Connective Tissue

Question 29

what are the most connective tissue consist of scattered cell embedded called?

Answer 29

Extracellular Matrix

Answer 39

Loose connective tissue, dense connective tissue, reticular tissue, and adipose tissue

Question 40

Loose connective tissue

Answer 40

consist of fibroblast and aoo three types of protein fibers embedded in a fel like ground substance, plus scattered macrophafes, mast cells and fat cells.
