Connective Tissues Quiz - Anatomy & Physiology

What type of cartilage makes up the discs in your spine?

What type of cartilage makes up the discs in your spine?

- fibrous cartilage

What type of cartilage can be found in the ear and in the tip of your nose?

- elastic cartilage

Most common tissue in body

- hyaline cartilage

Most common type of connective tissue

- areolar

Areolar tissue

- has cells surrounded by extrecellular matrix

Two parts of extracellular matrix

- ground substance and fibers

Ground substance in bone

- hard as a rock almsot because of the presence of of calcium

Extracellular matrix of blood

- is called plasma

- fluid gruond substance = gives ability to flow

Blood supply of connective tissue + ex

- most have a good blood supply (like bones - why they heal so fast)

Blood supply in tendons and ligaments

- hvae poor blood supply (injuries hear take a lot of time to heal)

What are tendons and ligaments made up of?

- dense connective tissue

Tendons

- connect bone to muscle

Ligaments

- conenct bone to bone

Collagen fibers

- high tensile strength

- most common protein in body

- ex: cartilage / bone tendons / ligaments

Most common protein in body

- Collagen fibers

Elastic fibers

- squishy

- external ear and tip of nose

Reticular fibers

- in reticular tissue

- in lymphatic organs like lymph nodes / spleen / bone marrow (squishy organs - gibers aren't strong like collagen but are strong enought o keep shape)

- does job of collagen fibers but just not as good because they are not as week

Cartilage Blood Supply

- no blood supply (avascular)

- injuried to cartilage take a long time to heal or never heal (beause of bad blood supply)

Fibers in Blood

- does not always have fibers (only when it clots)

- proteins that form those fibers are in blod right now but do not connect until told to do so (during clotting)

Bone

- cells in lucanea just just like in cartilage but dofference (what bone has that cartilage does not have)

- has calium in matrix that cartilage does not want

What would happen if cartilage received calcium?

- it becomes bone

- happened to every one of us (when we are born we are mostly cartilage so birth is easier

(after birth we have to start clarrifying the cartilage and starts to turn thsoe to bone

Hyaline

- most common connective tissue type

- in voice box / skeleton fetus

(guess hyaline if confused)

Dense Connective

- densly packed colalgen fibers (a bunch of collagen fibers packed together)

- pretty strong materials

- makes up tendons and ligaments

Adipose

- cells are filled with the fat and push stuff to side

- need for energy

- cushion organs

- isnulates us (under sking and keeps us warm)

Retiuclar

- has reticular fibers (squishy organs)

What is blood also known as?

- vascular tissue
