Answer 3

Reticular Loose Connective Tissue

Question 4

What are the two large classifications based on fiber density?

Answer 4

Loose and Dense

Question 5

Which connective tissue has high tensile strength, no elastin and low blood flow?

Answer 5

Regular Dense Connective Tissue

Question 6

Which connective tissue has extensive collagen with no pattern and strength in many directions?

Answer 6

Irregular Dense Connective Tissue

Question 7

Which connective tissue has sheets of elastic fibers made of elastin?

Answer 7

Elastic Connective Tissue

Question 8

What tissue provides some rigidity and flexibility at the same time?

Answer 8

Cartilage

Question 9

What are some characteristics of cartilage?

Answer 9

High water content, avascular and aneural

Question 10

What are the three types of cartilage?

Answer 10

Hyaline, Elastic, and Fibrous

Question 11

Why is multicellularity beneficial? Why would multicellularity have evolved?

Answer 11

Allows cell specialization, thus increasing efficiency of the body’s overall function.

Question 12

What is a tissue?

Answer 12

A group of the same type of cell performing the same specific function.

Question 13

What are the four major types?

Answer 13

Epithelial, Muscle, Nerve, Connective

Question 14

Why are cells separated in tissues separated into immature and mature types?

Answer 14

To carry out specific developmental patterns. The cell types are related in that they are both alive. Mature cells can go backwards for tissue repair, as needed.

Question 15

What is an important function of mature cells?

Answer 15

Monitors surrounding tissue and performs the tissue’s function

Question 16

What is an important function of immature cells?

Answer 16

Produces tissues and the surrounding extracellular matrix (ECM)

Question 17

The suffix -blast refers to what kind of calls?

Answer 17

Immature

Question 18

The suffix -cyte refers to what kind of cells?

Answer 18

Mature

Question 19

What is epithelial tissue?

Answer 19

A type of tissue that forms the covering on all internal and external surfaces. of your body.

Question 20

Secretion, absorption, and protection are the primary functions of what type of tissue?

Answer 20

Epithelial tissue

Question 21

What characteristics define epithelial tissue and how does it make it so beneficial?

Answer 21

Polarity, tight junctions, basement membrane support, highly innervated but avascular, ability to regenerate

Question 22

Why is muscle tissue so energy intensive?

Answer 22

Muscle cells fuel their chemical energy in the form of ATP, turning it into mechanical energy.

Question 23

What is connective tissue?

Answer 23

Cells embedded in an extensive ECM

Question 24

What are three types of fibers found in connective tissue?

Answer 24

Collagen, Elastic, and Reticular

Question 25

What does collagen fiber do?

Answer 25

stores, transmits forces, and dissipate energy within connective tissue

Question 26

What does elastic fibers do?

Answer 26

provides elasticity and extensibility to the dermis

Question 27

what does reticular fibers do?

Answer 27

acts a supporting mesh in soft tissues such as liver, bone marrow, and the tissues and organs of the lymphatic tissue

Question 28

Why does connective tissue have such extensive ECM?

Answer 28

Connective tissue has such extensive ECM because it gives the physical scaffolding for the cells. It also holds water, and provides a selective barrier to the external environment.

Question 29

Why does scar tissue form?

Answer 29

Due to damage under the epithelium

Question 30

What kind of tissues can easily form scar tissue?

Answer 30

Fibrous tissue can easily form scar tissue. Due to the scaffolding of collagen during scar tissue formation. Normal collagen fibers are woven together and are relatively flexible, as opposed to scar tissue collagen which are laid unidirectionally and not flexible.

Question 31

How does tissue repair work?

Answer 31

1.Damage is initiated below the epithelium and the underlying blood vessels. 2.Inflammation is triggered. This triggers blood pooling, which contains clotting factors and immune cells. 3.Clotting factors bring on scab formation. The scab is then pushed up to the epithelium, while the epithelial layer regenerates. WBC gets rid of debris. 4.Epithelial tissue completely regenerates. Scar tissue fills the space, the function of original tissue is lost. Blood vessels feed the new scar.

Question 32

Why are some tissues more repairable than others?

Answer 32

Blood flow or lack thereof.

Question 33

What is the most important factor in tissue repair?

Answer 33

Blood vessel growth, as vessels support cells during growth and or repair.
