Q

what does squamous mean ?

A

flattened

17
Q

what does cuboidal mean?

A

cube/round

18
Q

what does columnar mean?

A

taller than wide

19
Q

there are three subtypes to simple epithelia, what are they?

A

simple squamous (squished flat cells), simple cuboidal (cubed shaped) and simple columnar (column shaped cells)

20
Q

what subtypes are the to stratified epithelia??

A 
stratified squamous (flat)
stratified cuboidal (cubed shaped)
stratified columnar (column shaped)
21
Q

what is pseudostratified epithelia?

A

appears stratified but all cells sit on basement membrane= simple

22
Q

what is transitional epithelia?

A

cell shape varies with stretching. (found only on inner layering of urinary system) cuboidal to squamous when stretched.

23
Q

what kind of epithelium has exocrine and endocrine glands?

A

glandular epithelium

24
Q

what do unicellular exocrine glands do?

A

secrete mucus in the digestive urinary, reproductive and respatory tracts

25
Q

what do multicellular exocrine glands consist of?

A

secretory and duct cells

E.G. glands: sudoriferous (sweat), sebaceous (oil), mammary, digestive

26
Q

endocrine glands have ducts, true or false

A

false! they are ductless

27
Q

what are three functions of Epithelia?

A

Protection, secretion, control of permeability.

28
Q

are cells close or far apart in Connective Tissue?

A

far appart, separated by an extracellular matrix

29
Q

what do cell name ending in “blast” do? e.g. osteblast, chondroblast etc.

A

they create matrix

30
Q

what do cell names ending in “cyte” do? e.g. osteocyte, chondrocyte etc

A

they maintain matrix

31
Q

what do cell names ending in clast do?

A

they break down matrix

32
Q

between loose CT and Dense CT which is vascular??

A

loose CT is highly vascular

33
Q

does dense CT have little or many fibres?

A

many

34
Q

is cartilage vascular or avascular?

A

avascular

35
Q

is bone vascular or avascular?

A

Very vascular

36
Q

give me three subtypes of muscle tissue.

A

skeletal, cardiac, smooth

37
Q

what two cell types are in nervous tissue?

A

neurons and glial cells
