Answer 1

Osteoblasts

Answer 2

There are three types of muscle tissue:

skeletal (aka striated)

smooth (aka non-striated)

cardiac

Answer 3

There are three type of fibers in connective tissue.

From largest to smallest, they are:

collagen

elastic

reticular

Question 4

What type of tissue is fat?

Answer 4

Connecdtive, specifically proper connective tissue

Question 5

How are epithelial cells arranged?

Answer 5

Simple (one layer)

Startified

Pseudostratified (one layer that looks like several due to variations in nucleous placement.)

Question 6

What are the types of bone tissue?

Answer 6

Two types of bone tissue:

Spongy

Compact

Question 7

What’s the main purpose of epithelial tissue?

Answer 7

Epithelial tissue creates order and structure by lining and covering things.

They also secrete, absorb, and sense

Question 8

What is the ground substance in blood called?

Answer 8

Plasma

Question 9

What are the types of connective tissue- proper?

Answer 9

Connective tissue- proper has two types:

Dense

Loose

Question 10

Marfan Syndrome

Answer 10

genetic

weakens connective tissue over time

tall, thin, with loose flexible joints and long bendy fingers

Question 11

What does the nervous system do?

Answer 11

The nervous system senses, controls, and does mental activity.

Question 12

Does cartilage contain blood vessels? Nerves?

Answer 12

No, cartilage does not contain either blood vessels or nerves. Is it both avascular and aneural.

Question 13

Epithelial structures are referred to by what two characteristics?

Answer 13

arrangement and shape of cells. i.e.:

simple squamous

stratified cuboidal

etc.

Question 14

What are the four basic types of tissue in animals?

Answer 14

Four basic types of tissue in animals?

Muscular

Epithelial

Nervous

Connective

Question 15

What are the types of cartilage?

Answer 15

There are three types of cartilage:

hyaline

elastic

fibro-

Question 16

Instead of fibers like other connective tissue, blood has…

Answer 16

proteins dissolved in the plasma. They can form fibers when they’re needed for clotting.

Question 17

What do all types of connective tissue develop from?

Answer 17

Mesenchyme

Question 18

What are the types of dense connective tissue?

Answer 18

There are three kinds of dense connective tissue:

regular

irregular

elastic

Question 19

What are the types of connective tissue?

Answer 19

There are four types of connective tissue:

Proper

Cartilage

Bone

Blood

Question 20

What are the types of loose connective tissue?

Answer 20

There are three types of loose connective tissue:

areolar

reticular

adipose

Question 21

What are the components of most connective tissue?

Answer 21

There are three components of most connective tissue:

fibers

ground substance

cells

(Note that blood and lymph, for example, don’t have fibers.)

Question 22

Three types of cells in blood

Answer 22

Red cells (erythrocytes)

White (leukocytes)

Platelets (cell fragments that aid in clotting)

Question 23

What factor marks the difference between loose and dense connective tissues?

Answer 23

The difference between loose and dense connective tissue is in the ratio of ground substance to fibrous tissue.

Dense has:

more fibrous material

fewer cells

less ground substance.

Question 24

What type of tissue is a macrophage?

Answer 24

Macrophage is a type of white blood cell, and therefore connective tissue.

Question 25

What do -blast cells secrete?

Answer 25

Blast cells secrete fibers and ground substance that create the unique matrix that the adult cells "float" in.

Question 26

What part of conenctive tissue is non-living?

Answer 26

The Extra Cellular Matrix is non-living

Question 27

What are the marcromolecules?

Answer 27

Four types of macromolecules: carbohydrates lipids proteins nucleic acids

Question 28

Does epithelial tissue completely prevent anything from going through it?

Answer 28

No, it is selectively permeable. This helps it do its job.

Question 29

What are the main components of nervous tissue?

Answer 29

There are two components of nervous tissue: neurons glial cells

Question 30

Answer 30

The Integumentary System, Part 1 - Skin Deep: Crash Course A&P #6

Question 31

What's the difference between endocrine glands and exocrine glands?

Answer 31

The different is where they secrete their products. Endocrine glands secrete inside the body. Excocrine glands secrete outside their bodies. (Both kinds are still epithelial tissue, however,)

Question 32

Are epithelial cells polar?

Answer 32

Yes, they have an apical side and a basal side.

Question 33

What does the suffix 'cyte' mean?

Answer 33

mature cell

Question 34

How are stem cells differnt from progentior cells? From blast cells?

Answer 34

They are usually distinguished from progenitor cells, which cannot divide indefinitely... ...and precursor or blast cells, which are usually committed to differentiating into one cell type.

Question 35

What are the blast cells for cartilage?

Answer 35

Chondroblasts.

Question 36

What does the suffix 'blast' mean?

Answer 36

The cell is immature

Question 37

What shapes do epithelial cells come in?

Answer 37

Epithelial cell shapes: squamous columnar cuboidal

Question 38

what is the most abudnant and diverse tissue type?

Answer 38

connecdtive tissue
