connective tissue Flashcards
connective tissue purpose
Binds structure together: provides support, protection, framework, fills space, stores fat, produces blood cells, fights infection
what is connective tissue composed of
scattered cells within a matrix & ground substance and fibers
3 types of connective tissue cells
- mast cells (prevents clots)
- Macrophages (consumers)
- fibroblasts (produce fibers)
what are Collagenous fibers
strong, flexible, but not very elastic
Where are collagenous fibers found
Bone, ligaments, and tendons
what are Elastic Fibers
not as strong, very elastic
Where are elastic fibers found?
ears and vocal chords
where is Loose C.T.
it BINDs skin to organs
where is Adipose tissue
FAT, beneath the skin
where is Fibrous connective tissue
Tendons and ligaments
Loose CT function
forms thin membrane
Adipose function
protects, insulates and stores energy
Fibrous connective tissue function
bone to bone and muscles to bone
Hyaline cartilage location
covers ends of bones
Hylaine cartilage Function
serves as padding
Elastic cartilage location
ears and trachea
Elastic cartilage function
movements and flexibility
Fibrocartilage location
vertebrae (discs)
Osseous location
Skeleton
Fibrocartilage function
shock absorbtion
Osseous function
protection and support
Blood tissue location
circulates through body
Blood tissue function
carries oxygen and nutrients
what does the matrix contain
epithelial cells, macrophage, elastic fibers, mast cell, collagen fibers, ground substances, capillary, fibroblast, basement membrane
what do epithelial cells do?
cover inside and outside surfaces of body (simple squamous, stratified squamous, etc.)
what does the basement membrane do
provides cell and tissue support, thin and sheet like
what does macrophage do
costume bacteria
macrophage shape
round oval shape
fibroblast shape
long, flat, large
function of elastic fiber
provide elasticity and resilience to tissue
capillary function
transport blood, nutrients, and oxygen
capillary shape
very thin
mast cell shape
oval and irregular
ground substance function
active in development and movement of tissues
ground substance shape and description
transparent and colorless, fills space between cells
collagen fibers function
give skin strength and elasticity
loose ct vs fibrous/dense connective tissues
skin to organs and organs to organs vs muscle to bone and bone to bone
3 main types of cartilage
-hyaline, elastic, and fibrocartilage
what is tissue
a collection of cells
