Ch. 3 Advanced Cell And Skin Histology

Question 1

Lysosomes

Answer 1

Can be thought of as the cell’s garbage disposal system or recycling center. They digest waste material and food within the cell. Self destructive mechanism for the cell. When the cell dies, the Lysosome releases enzymes that help destroy the cell membrane. (Small cup)

Question 2

Vacuoles

Answer 2

Are often the largest of the organelles. They are the cell’s storage vats for molecules of waste and excess food supplies. Helps maintain pH and gives shape. (Large bowl)

Question 3

Ribosome

Answer 3

Very small organelles that are the protein construction department of the cell.

Question 4

Golgi Apparatus

Answer 4

Storage mechanism. Is a processing apparatus for large proteins that prepares them for secretion.

Question 5

Mitochondria

Answer 5

Are the cell’s lungs and digestive system converting oxygen to nutrients so they can be used as energy by the cell. Help break down simple sugars, fats, and parts of protein called amino acids.
(Energy producers, converts oxygen/nutrients to energy, converts oxygen to carbon dioxide, controls water)

Question 6

Tyrosinase

Answer 6

Enzyme that produces too much color

Question 7

Chemotaxis

Answer 7

Movement of an organism in response to a chemical stimulus

Question 8

Mitosis

Answer 8

When a cell separates into two identical sets of chromosomes.

Question 9

Ceramides

Answer 9

Waxy lipid molecules composed of springosine and fatty acid

Question 10

Integrins

Check answer….

Answer 10

Are transmembrane receptors that are the bridges for cell-cell and cell-extra cellular matrix interactions. Protein that holds the plaque to the nasal lamina.

Question 11

Superoxide

Answer 11

An unstable (free radical), reactive single oxygen atom

Question 12

Reticulocyte

Answer 12

A cell that is part of the blood cell line and forms from the acidophilus normoblast , it is 8um in diameter and contains mitochondria.

Question 13

Granulocyte

Answer 13

“Hollow Vessel” white blood cells (neutrophils, eosinophils, and basophils) bearing granules (vacuoles) in their cytoplasm that stain deeply.

Question 14

Mesenchymal

Answer 14

Embryonic connective tissue

Question 15

Fibrocyte

Answer 15

A cell that is not fully differentiated (it can go forward and backward in life), makes the most abundant protein in the body called collagen and originates from the Mesenchymal tissue; also knows as fibroblast.

Question 16

Neural Crest

Answer 16

Early nerve tissue in the embryo; the site of origin for melanocytes and a layer of the ectoderm germ layer.

Question 17

What is the cellular membrane made up of?

Answer 17

Is made up of a network of lipids (fatty material) and protein

Question 18

A stem cell is also know as a?

Answer 18

Mother Cell

Question 19

Lightening agents are used to block?

Answer 19

Tyrosinase and prevent melanin from being formed.

Question 20

There are how many layers in the stratum corneum?

Answer 20

15-20

Question 21

Elastin is found in the skin as well as in?

Answer 21

The lungs, bladder, and arteries

Question 22

What types of tissue is made to send signals to other organs?

Answer 22

Nervous tissue

Question 23

What immune cell is formed in the bone marrow?

Answer 23

T-cell

Question 24

The 2 divisions of the autonomic nervous system is?

Answer 24

Sympathetic and Parasympathetic

Question 25

The Ruffini Corpuscles are located in the?

Answer 25

Fingertips

Question 26

Cell

Answer 26

Basic unit of life and all functions go back to this.
