Connective Tissue (CT) Flashcards

1
Q

connective tissue (ct)

A

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)

Q

elastic fiber

A

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

Q

properties of areolar connective tissue

A

structure: all 3 types of protein
function: loosely attaches things together
papillary layer of dermis

Q

properties of adipose connective tissue

A

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

Q

properties of cartilage

A

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)

Q

properties of bone

A

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

Q

properties of fluid connective tissue

A

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)
