how vascularized is ct

A

well to poorly vascularized

43
Q

what is ct composed of

A

many cell types

44
Q

what does ct have a large amount of

A

extracellular matrix - non living or amorphis material

45
Q

two main types of ct

A

fibrous and specialized

46
Q

four types of fibrous ct (common ct)

A

loose (areolar and adipose), dense, elastic, reticular

47
Q

what is the purpose of loose ct (areolar and adipose)

A

surrounds the internal organs, muscles, and blood vessels

48
Q

what does dense ct do

A

forms tendons, ligaments, and deeper layers of the skin

49
Q

what is the purpose of elastic ct

A

surrounds hollow organs such as stomach and bladder that change shape or size regularly

50
Q

what is the purpose reticular ct

A

makes up internal framework of soft organs, like the liver, and the lymphatic system

51
Q

what is the main type of cell in fibrous ct

A

fibroblast

52
Q

what is a blast cell

A

the beginning cells for that tissue - they give rise to the other cells over time

53
Q

what are the three main types of fiber in ct

A

collagenic (regular), elastic, reticular

54
Q

what is collagenic (regular) fiber

A

white in color, most abundant, forms bones, dentin, organ capsules, dermis in skin, etc

55
Q

what are elastic fibers

A

very thin fibrils that can stretch like a rubber band

56
Q

what are reticular fibers

A

can combine with other fibers, found in smooth muscles, blood organs, and found in wound repair

57
Q

what are the four main types of specialized ct

A

cartilage, blood, bone, adipose

58
Q

what is cartilage ct

A

the matrix has collagen and a larger amt of water than fibrous tissues, not vascularized, different types

59
Q

what is blood ct

A

plasma is the matrix, has wbcs rbcs and platelets

60
Q

what is bone ct

A

contains few living cells in a matrix that hardens due to calcium and phosphate but is well vascularized

61
Q

what is adipose ct

A

composed of adipocytes little fibers and almost no ground substance

62
Q

what is the purpose of adipose ct

A

to insulate, protect, and reserve energy

63
Q

what are the three main types of muscle tissue

A

skeletal, cardiac, smooth

64
Q

what do all three of the muscle tissues have/are

A

arranged next to each other with minimal extracellular fluid, has many internal fibers which are arranged to shorten the cell, and is composed of a cell called muscle fiber

65
Q

how/what is skeletal muscle attached to

A

attached to the skeleton by tendons (its also well vascularized)

what are neuroglial cells

A

special supporting cells that protect, support, and insulate NEURONS

71
Q

what are neurons

A

specialized cells that recieve stimuli (irritability) and conduct waves of excitation along the axons and dendrites

72
Q

definition of an organ

A

2 or more TISSUES that work together to perform a function

73

A

integumentary

74

what system’s functions are protection and support of body organs, providing muscle attachment for movement, side of blood cell formation, and mineral storage

A

skeletal

75
Q

what system’s functions are production of movement, maintaining of posture, and production of heat

A

muscle

76
Q

what system’s functions are fast acting control system, responding to internal and external change, activation of muscles and glands

A

nervous

77
Q

what system’s functions are secretion of regulatory hormones, growth, reproduction, metabolism

A

endocrine

78
Q

what system’s functions are transportation of materials to and from all cells, body temp maintenance, participation in defense against disease and injury

A

cardiovascular

79
Q

what system’s functions are returning excess tissue fluid to circulatory system, participation in both general and specific immune response

A

lymphatic

80
Q

what system’s functions are gas exchange between air and blood, participation in producution of sound

A

respiratory

81
Q

what system’s functions are maintaining the volume and composition of body fluids, excretion of some waste products

A

urinary

82
Q

what system’s functions are providing body with water and nutrients, synthesize proteins and lipids for body, inactivates many substances like hormones, toxins and drugs

A

digestive

83
Q

what system’s functions are production of egg or sperm, nurture developing embryo until birth, provide sperm

A

reproduction

84
Q

def of homeostasis

A

maintenance of a stable environment

85
Q

what are survival needs of all systems and cells

A

nutrients, water, oxygen, stable body temp, atmospheric pressure

86
Q

how/what does the body communicate through

A

nervous and endocrine systems

87
Q

what is all a part of the control systems

A

receptors (respond to changes and send info), control center (determines normal), effector (provides means for response)

88
