Q

Transitional epithelial

A

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.

Q

Simple cubodial

A

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

Q

Stratified columnar

A

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

Q

Tight Junction

A

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

Q

superior

A

top of body

19
Q

inferior

A

bottom of body

20
Q

anterior

A

front of body

21
Q

posterior

A

back of body

22
Q

lateral

A

outside the body

23
Q

medial

A

middle of the body

24
Q

proximal

A

closer to axial skeleton

25
Q

distal

A

further away from axial skeleton

26
Q

Negative feedback

A

Helps ensure the appropriate reaction is occurring and gives the systems of the body a state of equilibrium

Our bodies preform negative feedback

27
Q

reticular fibers

A

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

28
Q

collagen fibers

A

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

29
Q

Adipocytes

A

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

30
Q

Mast cells

A

send signals to tell macrophages to move.

31
Q

macrophages

A

picks up waste
eats up stuff
picks up bacteria

32
Q

fibroblast

A

Only cells that are always present in connective tissue

Secrete proteins

makes fibers depending on where they are

33
Q

mesenchymal cells

A

grows into other specialized cells

34
Q

Types of connective tissue

A

connective tissue fiber, fluid connective tissue, supporting connective tissue

35
Q

Aerola tissue

A

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

36
Q

Adipose tissue

A

stores fat and has adipocytes

37
Q

Reticular tissue

A

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

38
Q

osseus tissue

A

AKA bone tissue

made up of mostly calcium

protects other tissue from damage

39
Q

Hyaline cartilage

A

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

40
Q

fibocartilage

A

It is dense and holds more weight

41
Q

Connective tissue proper regular

A

defined by dense collagen fibers

made up of fibroblast

They go in the same direction and take up majority of the tissue

42
Q

Connective tissue proper irregular

A

made up of collagen fibers
the main cell types is fibroblast

is found under the skin

irregular tissue fibers go in a irregular pattern.
