sweat glands, oils, salivary, secrete products into ducts mos numerous

31
Q

unicelluar

A

no ducts mucin production in humans cells in intestines

32
Q

mulitcelluar

A

2 major groups- simple (single and unbranched) compound (branching or divided)

33
Q

tubular

A

ducts from tubes

34
Q

alveolar

A

small and little sacs (lungs)

35
Q

tubuloalveolar

A

both

36
Q

merocrine

A

mostly exocrine done by exocytosis sweat gland and pancrease

37
Q

holocrine

A

cell fills up and then burst sebaceous secretion

38
Q

apocrine

A

apex fills up and pinches off and secretion is released

39
Q

mixed exocrine

A

salivary glands example

40
Q

serous gland

A

secretion that is watery

41
Q

mucous gland

A

thicker mucin secretion

42
Q

connective tissue

A

most abundant functions in binding support protect insulation and transportation. (blood is a connective tissue) arises from the mesoderm embryonic tissue. different degrees of vascularity some have non and some have a lot none to hit matrix composed of non living intercellular material.

43
Q

ground substance

A

fluid fills space between cells contains fibers and functions as a filter

44
Q

fibers

A

protein fibers collagen elastic and reticular fibers.

45
Q

connective tissue proper

A

cell type fibroblast

46
Q

cartilage

A

cell calle chondroblast

47
Q

bone

A

osteoblast cell

48
Q

blood

A

hemocytoblast (cell)

49
Q

4 classes of connective tissue

A

proper, cartilage, bone, blood

50
Q

loose (areolar)

A

semi fluid ground substance 3 fiber types fibroblast are most prominent. functions as a packing around organs providing cushing support epithelia surrounds blood vessels and nervous store lipids

51
Q

loose (adipose)

A

large number of fat cells mostly cellular little matrix almost clear used for protect and insulation. Has slow heas loss but primary function is nutrient storage

52
Q

loose (reticular)

A

many fibers and ground substance found in spleen lymph nodes and bone marrow

53
Q

dense regular

A

closely packed fibers of collagen found in ligaments and tendons

54
Q

dense irregular

A

irregular arrangement of collagen in skin dermis

55
Q

dense elastic

A

elastic fibers and strethces

56
Q

cartilage hyaline

A

see this everywhere gristle, most abundant provides support found in fetal skeleton

57
Q

fibrocartilage

A

thick collagen found in interverable disc in knee cartilages

58
Q

elastic cartilage

A

elastic fiber lie in your ear. epligadis

59
Q

blood

A

a fluid connective tissue where cells are suspended in a watery matrix with dissolved proteins,

60
Q

bone

A

calcified matrix functions support protection

61
Q

mesenchyme

A

mesoderm leads to differentiation meaning go on to become what they are suppose to b.

62
Q

muscle tissue

A

cells are elongated and highly celullar

63
Q

3 types of muscle tissue

A

skeletal cardiac smooth

64
Q

skeletal muscle

A

attached to bones, functions in movements, voluntarily

65
Q

cardiac muscle

A

walls of the heart pumps blood invuluntairy

66
Q

smooth muscle

A

hollow organs stomach bladder propel substance through the organs

67
Q

nervous tissue

A

brain, spinal cord- regulates and controls body functions

68
Q

neurons cells

A

generate and conduct impulses

69
Q

nerogleo

A

not conducted support insulate and protect nuerons

70
Q

tissue repair

A

inflammatory response occurs when tissue are injured

71
Q

regineration

A

proliferate the same type of cell. age is a factor nutrition and health

72
Q

fibrosis

A

proliferation of your fibrous connective tissue in in most tissue repair is going to involve both regeneration and fibrosis
