Exam 6 Material (Animal Tissues)

Question 1

What is being described?:
- A group of closely related/similar cell types that carry out specific functions?

Answer 1

Tissues

Question 2

Which type of tissue is being described?:
- Tightly fitted together to form a continuous layer or sheet (ex: skin, lining of digestive tract)

Answer 2

Epithelial tissue

Question 3

Anything that enters or leaves the body has to cross what at some point?

Answer 3

Epithelium

Question 4

How many different cell types make up epithelial tissue?

Answer 4

3

Question 5

What are the 3 different cell types that make up epithelial tissue?

Answer 5

• Squamous cells
• Cuboidal cells (has a cube shape)
• Columnar cells (are long and thin)

Question 6

How do we classify epithelial tissues?

Answer 6

Based on how many layers they have

Question 7

What does it mean for an epithelial tissue to be “simple”?

Answer 7

They only have one layer of cells

Question 8

What does it mean for an epithelial tissue to be “stratified”?

Answer 8

It will have multiple layers of cells

Question 9

What does it mean for an epithelial tissue to be “pseudostratified”?

Answer 9

It means that you really have one layer of cells but the way the cells are laid out will make it appear as though you have multiple layers of cells

Question 10

What is being described?:
- are made up of epithelial tissue and depending on the type of _____, it will release them onto am epithelial surface

Answer 10

Glands

Question 11

Which type of gland is being described?:
- are glands that have ducts that exit/empty onto epithelial surfaces (ex: sweat glands)

Answer 11

Exocrine glands

Question 12

Which type of gland is being described?:
- are ductless and they feed either directly into blood (then into the rest of the body) or tissue fluids (do NOT empty onto epithelial surfaces)

Answer 12

Endocrine glands

Question 13

Which type of tissue is being described?:
- cushion organs, generally consist of fibers (collagen, elastic, or reticular fibers) (lots of types)

Answer 13

Connective tissues

Question 14

Which type of connective tissues tends to provide support for various structures?

Answer 14

Loose and dense connective tissues

Question 15

Which type of connective tissue is being described?:
- Has elastic fibers and it is useful for the expansion of structures (ex: lungs/blood vessels)

Answer 15

Elastic connective tissue

Question 16

Which type of connective tissue is being described?:
- is formed by reticular fibers and provides support/framework for liver, lymph nodes, spleen (the skeleton that makes up these organs)

Answer 16

Reticular connective tissue

Question 17

Which type of connective tissue is being described?:
- is important for staring fat
- also important for installation/for supporting structures
- can be pads for internal organs

Answer 17

Adipose connective tissue

Question 18

Which connective tissue is being described?:
- is flexible and provides support

Answer 18

Cartilage (connective tissue)

Question 19

Which connective tissue is being described?:
- provides major support in vertebrates
- also provides protection (ex: ribcage protecting internal organs)

Answer 19

Bone (connective tissue)

Question 20

Which connective tissue is being described?:
- are important for circulatory travel tissues (will move oxygen with red blood cells, and immune/white blood cells through the body)
- lymph also helps to clean up the mess of fluid loss

Answer 20

Blood (connective tissue)

Question 21

How many types of muscle does muscle tissue have?

Answer 21

3

Question 22

What are the 3 different types of muscle tissue?

Answer 22

-Skeletal
- Cardiac
- Smooth

Question 23

Which type of muscle tissue is being described?:
- is attached to the skeleton/connects to bone and cartilage
- when it contracts, it will move body structures
- is a voluntary muscle (the nervous system can start and stop it)
- these muscles are thin, long, and cylindrical with blunt ends
- they have striations (stripe-like patterns)
- they have multiple nuclei
- can contract very rapidly with relatively high fatigue

Answer 23

Skeletal muscle

Question 24

Which type of muscle tissue is being described?:
- makes up the walls of the heart
- is an involuntary muscle
- are elongated, cylindrical fibers that branch and fuse
- have striations
- have intercalated disks (helps connect them)
- have only one nucleus per cell
- they contract at intermediate rates and their resistance to fatigue is intermediate

Answer 24

Cardiac muscle

Question 25

Which type of muscle tissue is being described?:
- lines the walls of the stomach, intestines, arteries, and other blood vessels
- is an involuntary muscle
- form elongated, spindle-shaped, and has pointed ends
- do not have striations
- have only one nucleus per cell
- are relatively slow in their contractions but they do not fatigue (have lots of endurance)

Answer 25

Smooth muscle

Question 26

Which type of tissue is being described?:
- makes up the nervous system
- is made up of (neurons—fundamental cell of the nervous system, and glial cells—acts as insulators)

Answer 26

Nervous tissue

Question 27

What is the basic makeup of a neuron?

Answer 27

The cell body/soma (which has spread out structures called dendrites and elongated structures called axons—the “wires” that sends messages to other cells/often another neuron that will form a synapse—space where two cells will meet up and sends messages to each other)

Question 28

What do clusters of axons form?

Answer 28

Nerves

Question 29

What do clusters of cell bodies form?

Answer 29

Nuclei of a cell region
