Anatomy- Connective tissue

Connective tissues are different from others because

extracellular matrix

Connective tissues have good blood supply besides

cartilage and dense connective

Strong collagenous fibers are made of what protein?

collagen

Elastic fibers are made of what protein?

elastin

Loose connective forms connections throughout the body that

bind body parts together

Loose connective are found 

under the skin, between muscles and around organs

Loose connective cells are called

fibroblasts

Fibroblasts are separated by a gel-like matrix that contains

collagenous and elastic fibers

Adipose tissue is designed to

store fat

Adipose tissue is found

beneath the skin, around joints, padding the kidneys, behind the eyeballs, and other internal organs

Adipose tissue functions are to

protect organs (kidneys and organs) cushion joints, insulation (under skin) and used for energy storage

Cells in adipose tissue are called

adipocytes

Adipocytes contain

fat droplets that pushes the nucleus to the side

Dense connective tissues consists of 

densely packed collagenous fibers (strong) 

Dense connective is found in

tendons and ligaments

Cartilage forms models for

bones

Cartilage cells are called

chondrocytes and lie within lacunae

most common cartilage type

hyaline

Hyaline cartilage if found at

end of bones, supports respiratory passages, and nose and rib cage

Most bones form

hyaline cartilage

Elastic cartilage is the most flexible and is found in

ears and parts of the larynx

Toughest cartilage is 

fibrocartilage 

Fibrocartilage provides a shock-absorbing function in

intervetebral disks, knees, and pelvic girdle

Bone is the most

rigid connective tissue

Bone supports

the body, protects, forms muscle attachments, stores calcium and is site for blood cell formation

does bone have a good blood supply

an excellent one

Bone matrix is deposited in layers called

llamellae

Llamellae forms circles around the

central canal

The central canal contains a

blood vessel

The canaliculi carries

nutreints from blood vessels to osteocytes

spaces called

lacunae house the osteocytes

the whole unit is called

osteon

blood is composed of

red and white blood cells

blood liquid matrix is called

plasma

blood functions transports

substances throughout the body

luekemia is noticed when there is

abnromal amount of white blood cells
