Q

pseudo-stratified columnar epithelium located

A

Trachea

26
Q

Why are gap junctions important in the heart

A

allow cells to contract together

27
Q

Functions of tight junctions

A

Seals intracellular spaces and waterproof

28
Q

Whats allows adhering and maintain integrity of epithelia cells

A

Desmosomes Junctions

29
Q

Whats stronger desmosome junctions or tight junctions

A

desmosomes

30
Q

What does every cell make contact with

A

basal laminar

31
Q

what do hemidesmosomes do

A

attach cell to ECM

32
Q

Small bundled up gland closer to the surface

A

Acinar

33
Q

Long gland further away from the surface

A

Tubular

34
Q

Mucus gland more likely to be acinar or tubular

A

acinar

35
Q

myoepithelial cells more likely to be found on cells secreting

A

mucus (thick secretions)

36
Q

Whats stored in vesicles of endocrine glands

A

Proteins

37
Q

Example of endocrine gland and its secretion

A

Pancreatic islets and insulin

38
Q

Endocrines secrete into blood vessels by what process

A

exocytosis

39
Q

Why are epithelia tissues arranged in rows between blood vessels in the Liver

A

Maximise blood flow

40
Q

Epithelium line what is digestive system

A

Bial ducts and Blood vessels

41
Q

Epithelium cells line what in Kidney

A

Blood vessels and renal pelvis

42
Q

Under proliferation and over proliferation of pituitary gland cause what abnormal functions

A

dwarfism and gigantism

43
Q

Over secretion of mucus gland in uterine tube can cause

A

in-fertilisation as eggs can’t move

44
Q

What is connective tissue made up of (2 main components)

A

ECM and proteins

45
Q

Examples of connective tissue

A

Blood, Bone, adipose, cartilage, proper

46
Q

ECM composed of

A

Ground substance and fibre matrix

47
Q

Connective tissue proper is either

A

loose or dense

48
Q

Areolar connective tissue function

A

spongy layer holds intracelular fluid, and protection as where macrophages, mast cells and white blood cells

49
Q

Loose connective tissue 3 types

A

Areolar, reticular and adipose

50
Q

Function of adipose and example

A

required to protect your organs and help maintain your body temperature e.g. fat

51
Q

Function of reticular and example

A

Forms the soft internal skeleton of something e.g. spleen and lymphoid organs

52
Q

Where is areolar connective tissue widely disrupted

A

under epithelia of the body

53
Q

Three Dense connective tissues

A

Regular, Irregular and elastic

54
Q

Dense connective tissue has what more of what compared to loose, and connective tissue has more

A

collagen fibres, ground substance

55
Q

Protein fibres of ECM

A

collagen, reticular and elastic

56
Q

Difference between dense regular (e.g.) and irregular (e.g.)

A

Dense regular only pulls in one direction e.g. tendon where irregular allows movement in different directions e.g. shoulder

57
Q

Dense Regular collagen fibres compared with Dense Irregular

A

Regular colagen fibres arranged parallel,

58
Q

Where do cells in Connective tissue mostly secrete

A

Into ECM

59
Q

Cells in connective tissue

A

Macrophages, WBC, fibroblasts, mast cells, adipose cells, osteoblasts,

60
Q

Best example of loose connective tissue

A

blood

61
Q

Loose compare to dense have

A

less fibres and more ground substance

62
Q

All connective tissue develop from

A

Mesenchyme (undeveloped loose connective tissue)
