A&P unit 1

Question 1

Tissue

Answer 1

collection of cells that preform a specific function

Question 2

Polarity

Answer 2

Refers to the structural and functional differences between the exposed and attached surfaces.

Question 3

Transitional epithelial

Answer 3

A mixture of cubodial and squamos : Goes from cubodial to squamos
An example of this would your bladder stretching to squamos when it is time to be released.

Question 4

Gap Junction

Answer 4

Send signals and coordinates tissue, channels are connecting to each other and there cytoplasm is connected throughout the cell.

Question 5

Regeneration

Answer 5

shedding, differentiation, proliferation

Question 6

What are epithelial tissue categorized by?

Answer 6

Layers and shape

Question 7

Simple squamos

Answer 7

Located in protective places, good for absorption and diffusion, really thin, good for gas exchange and controlling friction (one layer)

Question 8

Stratified squamos

Answer 8

Really squishy
skin has alot of this
it is protective

Question 9

Simple cubodial

Answer 9

Good for holding things in there shape
Occurs where secretion and absorption take place
Good for glands
Not as squishy
Has a rigid shape

Question 10

Stratified cubodial

Answer 10

Same as simple cubodial, but has more layers

Question 11

Simple columnar

Answer 11

Located in the small intestine/ stomach
Happens where absorption and secretion take place
Protects from chemical stresses

Question 12

Stratified columnar

Answer 12

providing protection along portions of the pharynx, epiglottis, anus, and urethra, as well as along a few large excretory ducts.

It has 2 or more multiple layers

Helps food go down smoothly

Question 13

What are the three categorize of epethilial tissue

Answer 13

Cubodial, squmaos, columner

Question 14

Tight Junction

Answer 14

Two plasma membrane bound together from membrane proteins
Prevents water and solutes from passing between cells
Example: Tight junctions in digestive tract keep waste and enzymes in the lumen away from bisolateral surface and digesting

Question 15

Extracellular protein fibers

Answer 15

collagen
retecular fibers
elastic fibers

Question 16

Axial skeleton

Answer 16

focusing on the middle of the body (skull, ribcage)

Question 17

apendicular skeleton

Answer 17

Focuses on apendages (skin, arm, hand)

Question 18

superior

Answer 18

top of body

Question 19

inferior

Answer 19

bottom of body

Question 20

anterior

Answer 20

front of body

Question 21

posterior

Answer 21

back of body

Question 22

lateral

Answer 22

outside the body

Question 23

medial

Answer 23

middle of the body

Question 24

proximal

Answer 24

closer to axial skeleton

Question 25

distal

Answer 25

further away from axial skeleton

Question 26

Negative feedback

Answer 26

Helps ensure the appropriate reaction is occurring and gives the systems of the body a state of equilibrium Our bodies preform negative feedback

Question 27

reticular fibers

Answer 27

can be found surrounding the kidneys and liver holds organs in place provides structural support

Question 28

collagen fibers

Answer 28

squishy fiber provides structural support we find it in our skin, joints hold the vows in the heart in place

Question 29

Adipocytes

Answer 29

Really large vessicle that stores fat Example: When a fat person looses weight they end up with a lot of skin because the adipocytes cells shrink the skin it does not just go away

Question 30

Mast cells

Answer 30

send signals to tell macrophages to move.

Question 31

macrophages

Answer 31

picks up waste eats up stuff picks up bacteria

Question 32

fibroblast

Answer 32

Only cells that are always present in connective tissue Secrete proteins makes fibers depending on where they are

Question 33

mesenchymal cells

Answer 33

grows into other specialized cells

Question 34

Types of connective tissue

Answer 34

connective tissue fiber, fluid connective tissue, supporting connective tissue

Question 35

Aerola tissue

Answer 35

Loose tissue because it does not contain much fiber. surrounds stuff like the digestive, respiratory, and urinary tract.

Question 36

Adipose tissue

Answer 36

stores fat and has adipocytes

Question 37

Reticular tissue

Answer 37

Looks like broken spider webs Loose connective tissue proper made up of mostly cells

Question 38

osseus tissue

Answer 38

AKA bone tissue made up of mostly calcium protects other tissue from damage

Question 39

Hyaline cartilage

Answer 39

A supporting connective tissue Found in places that need cushion like our joints can be found at the end of long bones to reduce friction

Question 40

fibocartilage

Answer 40

It is dense and holds more weight

Question 41

Connective tissue proper regular

Answer 41

defined by dense collagen fibers made up of fibroblast They go in the same direction and take up majority of the tissue

Question 42

Connective tissue proper irregular

Answer 42

made up of collagen fibers the main cell types is fibroblast is found under the skin irregular tissue fibers go in a irregular pattern.
