Connective Tissue (CT)

Question 1

connective tissue (ct)

Answer 1

most diverse, abundant, widely distributed, and structurally varied of the 4 main tissue types (support, protect, and bind organs, “glue”)
mesoderm
blood, tendons, ligaments, bonds, and cartilage
adipose tissue (body fat)

Question 2

what are the 3 protein fibers?

Answer 2

collagen, elastic, reticular
strengthen and support

Question 3

collagen fibers

Answer 3

long, strong, and flexible cables, most abundant protein in human body (white fiber)

Question 4

elastic fiber

Answer 4

needs more movement, thinner than collagen, smaller, stretch easily and go back to resting length (walls of blood vessels)

Question 5

reticular fibers

Answer 5

thin, interwoven mesh, in organs

Question 6

properties of areolar connective tissue

Answer 6

loose CT (mobiliity)
structure: all 3 types of protein
function: loosely attaches things together
papillary layer of dermis

Question 7

properties of adipose connective tissue

Answer 7

loose CT (fat tissue, mobility)
structure: adipocytes (fat cells)
functions: cushion organs, store energy
subcutaneous fat

Question 8

properties of cartilage

Answer 8

supporting ct (helps structure body)
structure: chondrocyte (mature cartilage cell)
3 types: hyaline (glassy, strong, ribs to breast bone), elastic (flexible, ear), fibrocartilage (strongest, in between each vertebrae)

Question 9

properties of bone

Answer 9

supporting ct
osteoblast (make new), osteoclast (break down bone), osteocytes (mature bone cells)
types of bone: compact (dense, strong, durable), spongy (not as strong, lighter, coarse looking)
function: support, protection, nutrient storage

Question 10

properties of fluid connective tissue

Answer 10

fluid ct refers to blood and lymph
blood consists of: plasma (liquid portion, mostly water), erythrocytes (red blood cells, rbc, gas transport), leukocytes (white blood cells, wbc, immune function), platelets (clotting cells)
